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 | |---------------|-------| | Brand | FITLY | | Material | Thermoplastic Polyurethane | | Colour | Blue | | Capacity | 8.5 Fluid Ounces | | Special Feature | Folding,Lightweight,Valve | | Age Range (Description) | Any Age Group | | Product Care Instructions | Hand Wash Only | | Model Name | F2B | | Recommended Uses For Product | Cycling, Climbing, Running | | Number of Items | 1 | | Theme | Sport | | Reusability | Reusable | | Sport | Cycling, Climbing, Running, Hiking | | Net Quantity | 8.5 Milliliters | | Manufacturer | FITLY | | Global Trade Identification Number | 07432112145196 | | Item model number | F2B | | Product Dimensions | 7.01 x 7.01 x 19 cm; 20 g | | ASIN | B0BBG66G8T | ## Product Details - **Brand:** FITLY - **Material:** Thermoplastic Polyurethane - **Colour:** Blue - **Capacity:** 8.5 Fluid Ounces - **Special Feature:** Folding,Lightweight,Valve ## Images ![FITLY Soft Flask - 8.5 oz (250 ml) - Shrink As You Drink Pocket Soft Water Bottle for Hydration Pack/Running Vest- Folding Water Bottle for Running, Hiking, Cycling - Ski Water Bottles (FLASK250) - Image 1](https://m.media-amazon.com/images/I/71SeRkWeHeL.jpg) ![FITLY Soft Flask - 8.5 oz (250 ml) - Shrink As You Drink Pocket Soft Water Bottle for Hydration Pack/Running Vest- Folding Water Bottle for Running, Hiking, Cycling - Ski Water Bottles (FLASK250) - Image 2](https://m.media-amazon.com/images/I/81dwcbS4wLL.jpg) ![FITLY Soft Flask - 8.5 oz (250 ml) - Shrink As You Drink Pocket Soft Water Bottle for Hydration Pack/Running Vest- Folding Water Bottle for Running, Hiking, Cycling - Ski Water Bottles (FLASK250) - Image 3](https://m.media-amazon.com/images/I/71gFj31Uu-L.jpg) ![FITLY Soft Flask - 8.5 oz (250 ml) - Shrink As You Drink Pocket Soft Water Bottle for Hydration Pack/Running Vest- Folding Water Bottle for Running, Hiking, Cycling - Ski Water Bottles (FLASK250) - Image 4](https://m.media-amazon.com/images/I/71VLB0CXQzL.jpg) ![FITLY Soft Flask - 8.5 oz (250 ml) - Shrink As You Drink Pocket Soft Water Bottle for Hydration Pack/Running Vest- Folding Water Bottle for Running, Hiking, Cycling - Ski Water Bottles (FLASK250) - Image 5](https://m.media-amazon.com/images/I/71WRTqYekdL.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.co.uk/products/742288024-fitly-soft-flask-8-5-oz-250-ml-shrink-as](https://www.desertcart.co.uk/products/742288024-fitly-soft-flask-8-5-oz-250-ml-shrink-as) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-16*
