DETAILS Silicone Bite Valve Wide Bottle Opening Soft and Collapsible Pull up the straw to unlock (350ml / 600ml soft flask) Review: Good quality - Easy to fill and no leeks. Fits into running vest really well. Review: Great for hydration on longer runs - I bought these for use in my running vest and they are ideal. Quite difficult to get rid of the chemical smell/taste but I think that is a common thing. Unfortunately after a few months use I got a tear in one of the bottles so I'm down to having only 1 left. Guess that's just a bit of a hazard with these being the softer material ## Features - MATERIAL: Made of food grade TPU, the water bottle is soft and collapsible.

Will this swap work?** A: Probably not. This bottle is completely collapsible, and when the water level gets low, the straws cause the bottle to sag. **Q: Does this start to collapse when you drink? I want to omit hearing the water sloshing sound when I run?** A: Yes, it is. You gonna listen anithing. It is perfect for running **Q: Do all of the sizes and packs of 2 come with the straw?** A: No. The 250ml and 500ml did not come with the straw. **Q: Will this work with osprey enduro 6?** A: Sorry, we can not judge if the bottles can work with the osprey enduro 6. We suggest that you can contact with Osprey to ask about the size of the bottles pocket.. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality *by E***C on 28 May 2026* Easy to fill and no leeks. Fits into running vest really well. ### ⭐⭐⭐⭐ Great for hydration on longer runs *by A***R on 1 November 2024* I bought these for use in my running vest and they are ideal. Quite difficult to get rid of the chemical smell/taste but I think that is a common thing. Unfortunately after a few months use I got a tear in one of the bottles so I'm down to having only 1 left. Guess that's just a bit of a hazard with these being the softer material ### ⭐⭐⭐⭐⭐ Easy Hydration solution *by E***R on 27 March 2025* I have been using these for years now. Never leaked, i keep them in the freeze between uses & there is no taste or smell from them. They are so convenient, i have used them in my hydration pack, waste belt & also put one in my running shorts pocket, for short warm runs. The fact they roll up when empty is good for longer runs, better than hard bottles. ## Frequently Bought Together - TRIWONDER TPU Soft Folding Water Bottles BPA-Free Collapsible Flask for Hydration Pack - Ideal for Running Hiking Cycling Climbing (250ml/8.45oz - Pack of 2) - AONIJIE Hydration Vest Pack Backpack 5L Marathoner Running Race Hydration - Honey Stinger Energy Gel Variety Pack | 5 Packs Each of Gold and Organic Fruit Smoothie | Gluten Free & Caffeine Free | For All Exercises | Sports Nutrition for Home & Gym, Pre and Mid Workout --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/59892924-triwonder-soft-flask-tpu-foldable-running-water-bottle-bpa-free](https://www.desertcart.tn/products/59892924-triwonder-soft-flask-tpu-foldable-running-water-bottle-bpa-free) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-19*
