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 | B07WYW4LNW | | Additional Features | Collapsable, Freezable, Lightweight | | Best Sellers Rank | #163,694 in Sports, Fitness & Outdoors ( See Top 100 in Sports, Fitness & Outdoors ) #171 in Hydration Packs | | Bottle Type | Reusable running flask | | Brand | FITLY | | Brand Name | FITLY | | Capacity | 250 Milliliters | | Colour | Blue | | Container Type | Bottle | | Country of Publication | USA | | Customer Reviews | 4.1 out of 5 stars 832 Reviews | | Finish Types | glossy or matte | | Global Trade Identification Number | 07432112044048 | | Item Dimensions W x H | 7W x 19H Centimeters | | Item Type Name | water bottle | | Manufacture Year | 2018 | | Manufacturer | 0 | | Material | Thermoplastic Polyurethane | | Material Type | Thermoplastic Polyurethane | | Material Type Free | Rigid Materials Free | | Model Name | F2-Blue | | Number of Items | 1 | | Product Care Instructions | Hand Wash Only | | Recommended Uses For Product | sports | | Reusability | Reusable | | Shape | Rectangular | | Special Feature | Collapsable, Freezable, Lightweight | | Sport Type | Climbing, Cycling, Hiking, Running | | Style Name | Sporty | | Theme | Sport | | Unit Count | 1 Count | ## Product Details - **Bottle Type:** Reusable running flask - **Brand:** FITLY - **Capacity:** 250 Milliliters - **Colour:** Blue - **Material:** Thermoplastic Polyurethane ## Images ![Fitly FLASK250 - Soft Flask for Hydration Pack - Ideal for Running Hiking Cycling Climbing - Collapsible Water Bottle (8.5 oz - 250 ml) - Image 1](https://m.media-amazon.com/images/I/61ZaCXirLuL.jpg) ![Fitly FLASK250 - Soft Flask for Hydration Pack - Ideal for Running Hiking Cycling Climbing - Collapsible Water Bottle (8.5 oz - 250 ml) - Image 2](https://m.media-amazon.com/images/I/713Ew84RavL.jpg) ![Fitly FLASK250 - Soft Flask for Hydration Pack - Ideal for Running Hiking Cycling Climbing - Collapsible Water Bottle (8.5 oz - 250 ml) - Image 3](https://m.media-amazon.com/images/I/717F8rcOq9L.jpg) ![Fitly FLASK250 - Soft Flask for Hydration Pack - Ideal for Running Hiking Cycling Climbing - Collapsible Water Bottle (8.5 oz - 250 ml) - Image 4](https://m.media-amazon.com/images/I/71ttUqFdXfL.jpg) ![Fitly FLASK250 - Soft Flask for Hydration Pack - Ideal for Running Hiking Cycling Climbing - Collapsible Water Bottle (8.5 oz - 250 ml) - Image 5](https://m.media-amazon.com/images/I/71YJUvrKJSL.jpg) ## Questions & Answers **Q: Can a sawyer mini or like be used with this product? would be perfect size for my grandson's outdoor pack.** A: Just tried it on the 150, the sawyer mini and sawyer squeeze don't fit. They're both a hair too small. It looked so promising. If Fitly made the threading a little smaller it would fit. **Q: What are the dimensions?** A: 5 3/4 in tot length (14.5cm). 2.5 in wide (6cm). About 1 in thick at the top, none at the bottom to be easily inserted in pockets. Because it shrinks as you drink, the dimensions are for a filled flask. **Q: What are the dimensions of the 500ml flask?** A: The FLASK500 is 8 inches tall by 6 wide. **Q: How do you clean this? Especially the mouthpiece where I’d assume would harbor germs.** A: If you look at the mouthpiece closely, it is not difficult to take it apart, wash it and put it back together. Call us if you need more guidance. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Cok iyi *by N***T on 9 June 2024* Maraton ve orta mesafe koşulları için çok güzel. ### ⭐⭐⭐⭐⭐ Ottima *by C***N on 4 February 2021* Ottima comodissima per andare a correre o da portare nel marsupio della bici.

Alltså inget lock mer än att skruva av för att fylla den. Funkar. ## 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.pt/products/446481318-fitly-flask250-soft-flask-for-hydration-pack-ideal-for-running](https://www.desertcart.pt/products/446481318-fitly-flask250-soft-flask-for-hydration-pack-ideal-for-running) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-23*
