Our collapsible water bottle is a compact and eco-friendly way to stay hydrated on the move! The soft water bottle is the perfect hydration tool for active individuals. Our soft flasks shrink as you drink, taking up minimal space and won’t slosh around, making it perfect for runners and vigorous activities. - SHRINKS AS YOU DRINK: Our collapsible water bottle is uniquely designed to shrink as you drink. This ensures the water doesn’t slosh around, bounce or rattle. The flexible design shapes to your hand & body, meaning the soft flask is never unwieldy. Our flexible water bottle features an intelligent bite valve & leak-resistant mouthpiece. - STAY LIGHT ON YOUR FEET: FITLY’s collapsible flask is purposely lightweight ensuring your light on your feet and not weighted down by unnecessary bulk. At FITLY, reusability is deeply important to us, and our water bladder is no exception. Enjoy limitless use from our collapsible water bottle that is 100% BPA & PVC-free. - HYDRATION ON THE MOVE: Our soft flask is specially crafted for vigorous activities such as running, hiking, cycling and climbing. The perfect sporting companion, take it everywhere with you! Our soft water bottle can be folded and tucked into your pocket or bag. Our soft flask comes in 5 size variations and are freezable so they can double as an ice pack. - DIRECTIONS FOR USE: We recommend rinsing the flask thoroughly before first use. If you experience taste mix ½ a teaspoon of BAKING SODA with water, shake and rinse. Users have also found the following to be useful: Fill with MILK, shake, and rinse. Add drops of lemon. Let an orange peel or tea bag set in the flask for a couple of hours. To hydrate, simply softly bite the mouthpiece and press the soft flask and enjoy! The harder you press, the faster the liquid will exit. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08NNGYF46 | | Age range | Adult | | Batteries included? | No | | Best Sellers Rank | 19,206 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) 264 in Cycling Bottles | | Brand | FITLY | | Color | Blue | | Customer Reviews | 4.2 4.2 out of 5 stars (144) | | Date First Available | 17 Nov. 2020 | | Features | Freezable, Leak Proof, Lightweight | | Included components | Flask (150ml), Flask (250ml), Flask (400ml) | | Item model number | COMBO | | Manufacturer | FITLY | | Material type | Thermoplastic Polyurethane | | Number of items | 3 | | Number of pieces | 3 | | Product Dimensions | 20 x 10 x 4 cm; 59 g | | Shape | Rectangular | | Size | COMBO | | Sport | Climbing, Cycling, Hiking, Running | | Style | Modern | | Usage | Hiking, Climbing, Cycling, Running | | Volume capacity | 400 Millilitres | ## Product Details - **Bottle type:** Soft Flask - **Brand:** FITLY - **Capacity:** 383 g - **Colour:** Blue - **Material:** Thermoplastic Polyurethane ## Images ![Soft Flask 3 Pack - 5 oz (150 ml), 8.5oz (250ml), & 13.5oz (400ml) - Shrink As You Drink Soft Water Bottle for Hydration Pack - Folding Water Bottle for Running & Hiking - Image 1](https://m.media-amazon.com/images/I/71OezlIgsiL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great *by B***S on 24 September 2025* Great set, whether it’s water or (sorry) alcohol - keeps cold for hours! ### ⭐⭐⭐⭐⭐ Excellent *by L***E on 27 December 2025* Great value for money ### ⭐⭐⭐⭐⭐ Excellent product *by M***N on 14 June 2025* Best running water bottles I’ve used!! ## Frequently Bought Together - FITLY Soft Flask 3 Pack - 5 oz (150 ml), 8.5oz (250ml), & 13.5oz (400ml) - Shrink As You Drink Soft Water Bottle for Hydration Pack - Folding Water Bottle For Running & Hiking - Running Water Bottle - FITLY Minimalist Running Pack - Running Backpack Phone Holder, Storage, Thoracic Belt - Carry Personal Items - Running Gear for Men & Women - Lightweight Running Water Backpack - FITLY Soft Flask - 5 oz (150 ml)- Shrink As You Drink Pocket Soft Water Bottle for Hydration Pack/Running Vest- Folding Water Bottle for Running, Hiking, Cycling - Ski Water Bottles (FLASK150) --- ## 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.com.br/products/524263137-soft-flask-3-pack-5-oz-150-ml-8-5oz](https://www.desertcart.com.br/products/524263137-soft-flask-3-pack-5-oz-150-ml-8-5oz) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-06-12*
