SoftBottle Collapsible 1L Water Bottle for Active Lifestyle


I recently picked up the Platypus SoftBottle 1.0L and I’ve been using it extensively for my daily commute and also during my weekend hikes. This bottle has truly lived up to its claims of being lightweight, flexible, and highly packable. When empty, the bottle can easily be rolled up and tucked away in my bag, saving a lot of space that would’ve otherwise been taken up by a rigid water bottle.

The design of the bottle is also quite thoughtful. The narrow middle section makes it comfortable to hold and the Push-Pull Cap ensures that the bottle is leak-proof and easy to open or close. Plus, it’s great to know that the materials used are BPA-free and taste-free, which is a major concern for many users.

However, I did face one issue. The bottle seems to be a bit delicate as I noticed a small leak from one of the seams after a few uses. But, I must admit that I was carrying a lot of heavy gear, so it might have been subjected to more stress than usual.

All in all, the Platypus SoftBottle 1.0L is a fantastic product that truly delivers on its promises of being lightweight, flexible, and easy to use. It’s perfect for anyone who wants a reliable, easy-to-carry water bottle for their daily adventures. Just be mindful of its delicate nature and take care of it accordingly.

High-Capacity Portable Water Purifier Bottle


I’ve been using the Sport Berkey Filter Water Bottle (22oz) for a few weeks now on my daily hikes, and I must say, it’s been a game-changer. The bottle is lightweight and durable, making it perfect for any outdoor activity. I love how I can fill it from any water source, like a stream or lake, and still get clean and safe drinking water.

The highlight of this product for me is its ability to filter out harmful contaminants, leaving me with fresh, great-tasting water whenever I need it. Another positive aspect is how easy it is to use - I just fill it up, twist on the cap, and I’m good to go! Its compact design also makes it super convenient to carry around, whether I’m on the trail or at the office.

However, there are a couple of drawbacks I’ve noticed. The first is that the bottle doesn’t hold as much water as I’d like due to the large filter inside. It’s a little heavier than I prefer too, mainly because I need to refill it constantly.

All in all, I’m really happy with the Sport Berkey Filter Water Bottle. It’s a reliable and portable water filter that has made staying hydrated during my hikes much more convenient. If you’re looking for a high-quality water bottle to take on your outdoor adventures, I’d definitely recommend giving this one a try!

Foldable Water Bottle for Hot & Cold Drinks


I recently got my hands on a Stojo Collapsible Water Bottle, and I must admit, it has been a game-changer in my daily hydration routine. The first thing that stood out to me was its unique, twist-cap design that creates an airtight, leak-proof seal. No more worrying about spills in my bag!

One feature that really impresses me is how easy it is to clean. The bottle comes apart for easy cleaning in the dishwasher, making it a much healthier option compared to other bottles that may build up bacteria in crevices. Its LFGB Certified silicone material ensures that the bottle is safe to use without any harmful chemicals like BPA, phthalates, or glues.

In terms of capacity, this 20 oz bottle provides a generous amount of hydration for any adventurous outing. The best part? It collapses into a compact size after use, making it incredibly convenient to carry around without taking up too much space in my bag.

However, there have been a few minor hiccups in my experience with this bottle. Some users have reported experiencing an unpleasant aftertaste, which may be attributed to the bottle’s silicone material. Additionally, there have been concerns about leakiness and difficulty in opening or closing the twist cap feature. That being said, these issues are subjective and may vary from person to person.

All in all, I believe the Stojo Collapsible Water Bottle offers a promising solution for on-the-go hydration needs. Its unique design, leak-proof seal, and easy-to-clean nature make it a top choice for those looking for a reusable water bottle that can keep up with their active lifestyle. While there may be some drawbacks to consider, such as the bottle’s aftertaste and insulation capabilities, these issues should not overshadow the overall convenience and practicality that the Stojo Collapsible Water Bottle provides.

Soft Cup Speed Foldable Water Bottle 150ml


I recently incorporated the Salomon Soft Cup Speed Water Bottle into my trail running gear and I’m glad I did. This soft, collapsible cup is perfect for cupless races, as it’s foldable and can be stored in my pockets or easily stood up for drinking on the move. Made from BPA-free material, this reusable bottle aligns with the eco-conscious trend in race events.

During my trail runs and hikes, I’ve found the Soft Cup Speed to be incredibly convenient. Its flexible design makes it easy to pack, while its capacity is just right for a quick sip of hydration. Its compatibility with mandatory hydration gear and kits for major races have also saved me time and effort.

However, one downside I’ve noticed is that due to its flexibility, it’s not the best insulator. If you’re carrying a hot drink or need to keep your beverage hot, this might not be the ideal choice. Additionally, the cup may become dirty or muddy during your race, so a cover would be a useful addition.

Overall, the Salomon Soft Cup Speed Water Bottle has made a positive impact on my trail running experience. Its innovative design has made hydration on the go a breeze, and its collapsible nature has saved me valuable space in my equipment. Though it may not be the best choice for warm drinks, it certainly deserves a place in the trail runner’s toolkit.

Insulated Soft Flask for Hiking


I recently got the chance to test out Salomon’s Soft Flask 400 ml/13 oz Insulated, and it has become my go-to bottle for all my adventures. From hiking to running, this lightweight flask has been a game-changer for me. The dual-skin insulation is truly impressive, keeping my water at the ideal temperature even on the hottest or coldest days.

One of the standout features of this flask is its soft, flexible structure. It fits comfortably in my pocket, and as I drink, it shrinks to minimize water bounce. The high-flow bite valve is another favorite feature, allowing me to take quick sips and even clear any ice buildup with a quick squeeze - perfect for those chilly winter hikes!

Another advantage of this flask is its versatility. It’s compatible with all of Salomon’s bags and summer lids, making it a perfect addition to my collection. The only minor drawback I’ve noticed is its 400ml capacity, but it’s a small price to pay for the convenience and performance this bottle offers.

Overall, I’ve been extremely satisfied with the Salomon Soft Flask 400 ml/13 oz Insulated. It’s become an indispensable part of my outdoor gear, and I highly recommend it to anyone looking for a reliable and practical water bottle solution.

Flexible Foldable Portable Soft Water Bottle


I’ve been using the Lixada Soft Bottle for my daily jogs and hikes, and it’s become my go-to water bottle. The flexibility of this TPU-constructed bottle is a game changer - I can easily fold it into a small size and stuff it into my backpack. The BPA-free quality ensures that the water tastes clean and fresh every time.

The soft bite mouthpiece is not just comfortable, but also ensures that I don’t spill a drop while guzzling water, even when I’m on the move. Plus, the leak-proof seal gives me the peace of mind that I won’t end up with a soaked backpack.

However, the softness of the bottle can make it a bit difficult to hold onto when I’m running at full pace. And while the 250ml capacity is enough for a short hike, I could use a bit more water for longer expeditions.

All in all, the Lixada Soft Bottle is a reliable companion for my outdoor adventures, offering convenience and hydration in a compact package.

Salomon Hydration Flask w/ Water Filter


I’ve been using the Salomon Soft Flask XA Filter for several long trail runs, and it’s been a game-changer. Not only does it help me carry less water weight, but its integrated filter ensures that I can safely drink from any water source we come across. The high-flow valve and wide cap make refilling and drinking a breeze. The flask’s compact size and leak-proof performance are extra bonuses.

One thing that really stands out is the absence of any unpleasant aftertaste, making my water taste just like water. It’s really easy to use and clean too. The only downside I’ve noticed is that the cap can be a bit tricky to secure properly at times.

In conclusion, if you’re an avid trail runner or explorer, the Salomon Soft Flask XA Filter is definitely worth considering. It’s light, reliable, and makes staying hydrated on the go a whole lot easier.

UltraFlask Soft Water Bottle for Hiking and Running


I recently tried the Orange Mud UltraFlask for my daily runs and it’s been an absolute game-changer. The soft flask is made from a super comfortable material that contours to any pocket, making it a breeze to stash and access on the go. I love how its size reduces as I drink, effectively minimizing water sloshing and keeping things compact.

What stands out most about this product is its versatility. You have the option of using the bite valve directly with the cap or attaching a tube for hands-free drinking - a feature that really came in handy during my long distance runs when I needed both hands for balance. The UltraFlask is also ice cube friendly, giving me the opportunity to have refreshingly chilled water even on the hottest of days.

On the downside, while the soft flask is compact and easy to stash, it can feel a bit bulky when full. However, as you start drinking, it collapses down, becoming more compact and less intrusive. This could be an issue if you’re trying to fit multiple flasks in your vest or jersey pocket, but for me, the convenience and functionality of the UltraFlask outweighed this minor inconvenience.

Another positive aspect of this product is its ease of use and cleaning. There’s no unpleasant aftertaste, and the bite valve can be disassembled for thorough cleaning. Additionally, it doesn’t leak, which is always a relief when you’re carrying valuable items in the same pocket.

Overall, I’ve been incredibly satisfied with the Orange Mud UltraFlask. Its unique design, versatility, and functionality have made it an essential part of my daily hydration routine. If you’re in the market for a high-quality hydration solution, I highly recommend giving the UltraFlask a try.

Lixada Foldable Silicone Water Bottle with Purifying Filter


I first used the Lixada Portable Bottle Soft Flask on a weekend hiking trip. Needing a lightweight, eco-friendly option, I decided to give this water bottle a try. The bottle’s unique design, with a foldable structure made from silica gel and TPU material, caught my attention right away. Its capacity of 500ml was more than enough to quench my thirst throughout the day.

One of my favorite features was the built-in filter element. This high-precision hollow ultrafiltration membrane effectively removes 99.9% of harmful bacteria in the water, providing a peace of mind when refilling from natural water sources in the wild.

Another pro was its portability. The soft structure made it easy to tuck into my backpack or even my pocket. The reusable filter was also a nice touch, allowing me to wash and reuse it for future trips, reducing waste.

However, there were a few cons. The water bottle’s mechanism required some getting used to. It took a few tries to learn how to bite on the nozzle to release the water. Additionally, the foldable design took up more space than traditional bottles, which could be an issue when packing light.

In conclusion, the Lixada Portable Bottle Soft Flask is a unique, environmentally friendly option for adventurers and eco-conscious people alike. Its large capacity, effective filter, and portability make it perfect for outdoor activities. However, its unique design and mechanics may take some time to adapt to.

I recently got to try out this Kemier Collapsible Water Bottle, and I’ve got to say, it’s been a game-changer for my daily hydration needs. I’ve taken it with me everywhere - from the gym to hiking trails, and it’s truly lived up to the expectation.

First off, this bottle is incredibly light and collapsible. When not in use, it folds down to about a third of its size, making it super easy to fit into my bag without taking up too much space. Plus, the silicone material is not only BPA-free but also odorless and approve by FDA in the U. S. , ensuring that I’m drinking from a safe and clean bottle.

The bottle’s 750ml capacity is perfect for keeping me hydrated throughout the day, and the wide lid makes it really easy to fill up with ice and water. Plus, the leakproof design ensures that I can toss it into my bag without worrying about any spills or mess. And speaking of convenience, I love how the collapsible design allows me to fold it down and clip it onto my bag after use.

However, there are a couple of cons I encountered while using the bottle. One being that it doesn’t keep water cold for too long, so I wouldn’t rely on it for long hikes or outdoor trips. Another issue is that, at times, the collapsible design can be a bit difficult to roll up, especially when it’s filled with water.

Overall, I’m really happy with this Kemier Collapsible Water Bottle. Its lightweight, foldable design makes it the perfect companion for all my outdoor adventures, and the leakproof feature ensures that I can toss it into my bag without any worries. While there are a few cons, the benefits far outweigh them, making this bottle a must-have for anyone in need of a convenient and eco-friendly hydration solution.

Salomon Soft Flask XA Filter 500ml: High-Flow Valve, Thermoplastic Polyurethane Material, Safe Solution for Liquid Storage


As a fan of trail running, I’ve put the Salomon Soft Flask XA Filter 490ml to the test, and I’m happy to report that it’s been a reliable companion on my adventures. The large 42mm diameter cap and high-flow valve make refilling and drinking a breeze, allowing me to focus on tackling the terrain ahead.

One of the standout features of this soft flask is its compatibility with all Salomon caps with a 42mm opening, making it easy to switch out if needed. The bottle’s flexibility and comfort add to its appeal, helping to reduce bounce and ensuring irritation-free contact with my body.

However, there are a few drawbacks to consider. Some users have reported issues with the filter getting jammed after a few uses, which can be frustrating, especially when needing a refill during a run. Additionally, the filter is only compatible with Salomon flasks released from spring 2020 onwards, meaning older models cannot be retrofitted with this filter top, leading to more plastic waste.

Overall, I’ve found the Salomon Soft Flask XA Filter 490ml to be a convenient and efficient way to ensure I have clean water on the go. If you prioritize speed and convenience over sustainability, this might be the perfect addition to your running gear.
