The soft water bottle is the perfect hydration tool for active individuals.

This ensures the water doesn’t slosh around, bounce or rattle. The flexible design of our hydration flask shapes to your hand & body, meaning the soft flask is never unwieldy. Our flexible running flask 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.

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 water bottle 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 | B07KNDT5J7 | | Additional Features | Freezable, Leak Proof, Lightweight | | Age Range Description | Any Age Group | | Best Sellers Rank | #8,765 in Sporting Goods ( See Top 100 in Sporting Goods ) #19 in Camping & Hiking Hydration Flasks | | Bottle Type | Flask | | Brand Name | FITLY | | Capacity | 5 Fluid Ounces | | Color | blue | | Container Type | Flask | | Customer Reviews | 4.1 4.1 out of 5 stars (3,482) | | Finish Types | Standard | | Included Components | FLASK150 | | Item Dimensions W x H | 7W x 14H centimeters | | Item Type Name | Running Accessory | | Item Weight | 0.02 Kilograms | | Manufacturer | FITLY | | Manufacturer Part Number | FLASK | | Material Type | Thermoplastic Polyurethane | | Material Type Free | BPA Free, PVC Free | | Model Name | Borraccia Morbida | | Model Number | FLASK | | Number of Items | 1 | | Number of Packs | 1 | | Product Care Instructions | Hand Wash Only | | Recommended Uses For Product | Running, hiking, cycling, skiing, and other vigorous activities | | Reusability | Reusable | | Shape | Rectangular | | Specific Uses For Product | Running, hiking, cycling, climbing, and other vigorous activities | | Sport Type | Cycling, Hiking, Running | | Style Name | Portable | | Theme | Sport | | UPC | 860164001264 | | Unit Count | 1.0 Count | ## Product Details - **Bottle type:** Flask - **Brand:** FITLY - **Capacity:** 5 Fluid Ounces - **Colour:** blue - **Material:** Thermoplastic Polyurethane ## Images ![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) - Image 1](https://m.media-amazon.com/images/I/61SkjFZCKDL.jpg) ## Frequently Bought Together - FITLY Soft Flask - Shrink As You Drink Soft Water Bottle for Hydration Pack - Folding Water Bottle Ideal for Running, Hiking, Cycling, Climbing & Rigorous Activity - Body Glide For Her Anti Chafe Balm | Chafing stick with added emollients | Great for dry, sensitive skin and/or sensitive areas | Use on chest, bra, butt, groin, arm, and thigh chafing | 1.5oz - Fitgriff® Running Belt for Men & Women - Secure Jogging Pouch for Phone, Keys & Essentials - For All Cell Phones --- ## 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.vu/products/314345868-soft-flask-5-oz-150-ml-shrink-as-you-drink](https://www.desertcart.vu/products/314345868-soft-flask-5-oz-150-ml-shrink-as-you-drink) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-12*
