Foldable Collapsible Sports Water Bottle


I recently got the Special Made collapsible water bottle, and it’s a game-changer for me! As an infrequent traveler, I always struggled with finding a water bottle that didn’t take up too much space in my bag. This one, however, is incredibly foldable, making it perfect for travel. I just pop it in my bag, and I’m good to go!

One of the things that really stood out to me is how incredibly safe this bottle is. It’s made of BPA-free food-grade organic silicone that’s free of PVC, latex, and phthalate. This means I can trust its safety for myself as well as my kids. Plus, it’s leak-proof, so I don’t have to worry about any spills in my bag.

The bottle is also really easy to clean, thanks to its wide-mouth design. I can easily reach in and give it a good scrub or add ice or lemon to it. It’s definitely a plus, considering how much of a pain cleaning regular water bottles can be.

One thing that could be improved, however, is the aftertaste that can linger. Overall, though, this water bottle has made hydration while traveling or doing outdoor activities so much easier and more enjoyable.

1.0L Flexible Water Bottle with Push-Pull Cap


There’s this innovative water bottle called the Platypus SoftBottle 1.0L that I got my hands on recently. If you were to ask me what was unique about it, it’s the lightweight and flexible design. This is not your regular bulky bottle; it’s as simple as that.

I have a small apartment with limited storage, and the Platypus SoftBottle’s compact form when empty is gold for me. Besides, the ridged center means I get a better grip when filling it with water. Once I’m done, it flattens effortlessly for easy storage, saving me precious space. Plus, the bottle is made from taste-free, BPA-free materials, so my drinking water remains just that - water!

The bottle comes with a choice between a Closure Cap or a Push-Pull Cap, and they both thread easily onto the bottle. I sometimes use these bottles with my Platypus drink tube, and it works just fine. But that’s the positive side of it.

Now for some downsides. After using this bottle for quite some time, I did encounter a small leakage issue near the top seam. I was pretty disappointed as this was not something I was expecting from such a trusted brand. Additionally, I should mention that the bottle threads are not compatible with a regular Sawyer squeeze filter, which was a minor inconvenience.

Although I had hoped for a leak-free and thread-compatible bottle, I will still recommend this product. I mean, it does make it easier for me to carry water around, especially while traveling or hiking. And let’s not forget, the compact size when empty is perfect for someone like me who’s always tight on space.

Here’s my take on the Platypus SoftBottle 1.0L - it’s an ingenious water bottle that’s perfect for travelers and hikers. Yes, there are minor issues that could be improved, but the benefits far outweigh them. If you’re like me and value the space-saving design and lightweight nature of this bottle, it’s worth giving it 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.

Portable and Flexible Hydrapak Stow Water Bottle


I recently came across the Hydrapak Stow Flexible Bottle, and it has been a game-changer in my daily hydration routine. This soft-sided flask is perfect for anyone on the go who wants the convenience of a lightweight, portable water bottle without sacrificing quality and durability.

One of my favorite features of the Hydrapak Stow is its unique folding construction. When empty, the bottle can be flattened and rolled up, making it easy to stow in your pocket or bag. Additionally, the retractable bail loop makes it a snap to carry when filled, and it securely holds the collapsed bottle in place.

The quality of this water bottle is evident in its BPA-free and PVC-free TPU material, which is highly abrasion-resistant and features RF-welded seams to bolster its overall durability. The screw cap is equipped with an integrated sealing and leak-proof drink nozzle, ensuring your belongings stay dry even if the bottle gets knocked around.

I also appreciate the ease of maintenance with the Hydrapak Stow. Although some users may experience an unpleasant aftertaste in the beginning, washing the bottle thoroughly and allowing it to air out should help eliminate this issue. And with Hydrapak’s incredible Beyond Lifetime Guarantee, you can trust that your investment is protected for years to come.

However, one minor drawback of the Hydrapak Stow is the slightly difficult opening and closing mechanism of the screw cap. While this does contribute to the bottle’s leak-proof design, some users may find this aspect challenging, especially during quick refills on the go.

In conclusion, the Hydrapak Stow Flexible Bottle has become an indispensable part of my daily life, allowing me to stay hydrated and healthy while on the move. With its innovative design, high-quality construction, and exceptional support from the manufacturer, the Hydrapak Stow is a top choice for anyone seeking a practical, portable, and efficient water bottle solution.

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.
