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.

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 | B0BBQ5T9PM | | ASIN | B0BBQ5T9PM | | Additional Features | Freezable, Leak Proof, Lightweight | | Age Range Description | Adult | | Best Sellers Rank | #45,630 in Sporting Goods ( See Top 100 in Sporting Goods ) #3,449 in Sports Water Bottles | | Bottle Type | Collapsible | | Brand Name | FITLY | | Capacity | 383 g | | Color | Black | | Container Type | Bottle | | Customer Reviews | 4.2 4.2 out of 5 stars (62) | | Customer reviews | 4.2 4.2 out of 5 stars (62) | | Date First Available | 30 August 2023 | | Finish Types | Glossy | | Global Trade Identification Number | 07432112146148 | | Included Components | Flask (150ml), Flask (250ml), Flask (400ml) | | Item Dimensions W x H | 8.9W x 17.7H centimeters | | Item Type Name | Flask | | Item Weight | 0.08 Kilograms | | Item model number | B-COMBO | | Manufacturer | FITLY | | Manufacturer | FITLY | | Material Type | Thermoplastic Polyurethane | | Material Type Free | Polyvinyl Chloride (PVC) Free | | Model Name | B-COMBO | | Number of Items | 3 | | Product Care Instructions | Hand Wash Only | | Product Dimensions | 8.9 x 8.9 x 17.7 cm; 82 g | | Recommended Uses For Product | Sports and Outdoor Activities | | Reusability | Reusable | | Shape | Cylindrical | | Sport Type | running, cycling, hiking, climbing | | Style Name | Sporty | | Theme | Sport | | Unit Count | 3.0 Count | ## Product Details - **Bottle type:** Collapsible - **Brand:** FITLY - **Capacity:** 383 g - **Colour:** Black - **Material:** Thermoplastic Polyurethane ## Images ![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 - Image 1](https://m.media-amazon.com/images/I/71A04c471cL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by G***P on 6 January 2026* L'utilisation de ce produit m'a agréablement surpris.

Wenn sie leer sind, kann man sie leicht verstauen. ### ⭐⭐ Review *by B***C on 30 August 2023* They got the job done, though they made the water taste very strongly of rubber after multiple washes with soap. The top part is a good design to prevent spilling, but horrible for trying to drink from it. It’s better to just unscrew the top altogether unless you want water everywhere. ## 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 - FITLY Minimalist Running Pack - Running Backpack Phone Holder, Storage, Thoracic Belt - Carry Personal Items - Running Gear for Men & Women - Lightweight Running Water Backpack --- ## 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.kr/products/566735584-fitly-soft-flask-3-pack-5-oz-150-ml-8](https://www.desertcart.kr/products/566735584-fitly-soft-flask-3-pack-5-oz-150-ml-8) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-18*
