## Description

desertcart.com : FITLY Soft Flask Running Water Bottle - Collapsible Hydration Flask | Shrink-As-You-Drink Soft Water Bottle with Bite Valve for Running Vests, Belts, Hiking, Cycling, Climbing and Skiing : Sports & Outdoors

Review: Perfect size & delivery for picky runners - A basic balancing act for runners is ensuring a handy source of hydration while avoiding too much bulk/weight. I find this flask is able to provide both for short runs in warmer conditions, longer runs in colder weather, or longer runs interspersed with watering stations. It’s small enough to fit into a pocket without bouncing around, its flexibility means it disappears as you consume the water, and its dispensing spout is very practical to use while running, managing to keep a tight seal without the need for twisting locks or the like.
Review: Hydrate and get thru TSA when empty!! - I’m always on the run and have needed medications that I have to take at different times. Not always a water fountain handy and this works great! Was just in Utah and helped with hydration in their dry climate! Top quality and easy to use and keep clean. By all means, get this! And when empty, it’ll glide through TSA at the airport. Fill it on the other side in one of those fancy water refills!

## Features

- SHRINKS AS YOU DRINK - The flexible FITLY soft flask compresses as liquid is used, helping reduce sloshing, bouncing and wasted space while you move. This running soft flask sits comfortably in a hand, pocket, running belt or compatible vest. Its lightweight shape makes hydration easier during running, hiking, cycling, climbing, skiing and other active days, then folds down for compact storage when empty. The compact format is designed for easy carrying before, during and after exercise.
- BITE VALVE FOR QUICK SIPS - Drink while moving by biting the silicone mouthpiece and gently pressing the flask. The intelligent bite valve and leak-resistant closure are designed for controlled flow without repeatedly unscrewing a rigid cap. Use this hydration flask for water, electrolyte drinks or energy gel during training, racing and outdoor activity. Rinse thoroughly before first use and clean after use. It stores neatly with the rest of your training or outdoor kit.
- LIGHTWEIGHT AND PACKABLE - This flexible water bottle gives runners and hikers a reusable alternative to bulky rigid bottles. It shapes to the hand and body, fits many running vest pockets and packs into a small space after use. The soft water bottle is suitable for short runs, longer sessions, cycling, hiking and travel when low weight and easy storage matter. Capacity and colour are shown in the title for simple variant selection. The reusable design supports regular training and travel.
- BPA AND PVC FREE TPU - FITLY soft water bottles are made from durable thermoplastic polyurethane and are free from BPA and PVC. The material is designed for repeated active use and can be frozen to help keep drinks cool or serve as a compact ice pack. A secure circular locking mechanism supports leak-resistant transport in a running bag, hydration vest, backpack or pocket between training sessions. The reusable design supports regular training and travel.
- BUILT FOR ACTIVE HYDRATION - Carry this running flask in front, side or back pockets and reach it without breaking stride. The collapsible design reduces bulk as you drink and helps keep your load quiet and stable. It is a practical running vest water bottle for runners, cyclists, hikers, skiers and climbers who want portable hydration without the weight of a hard bottle. Select the capacity that suits your distance and route. It stores neatly with the rest of your training or outdoor kit.

### ⭐⭐⭐⭐⭐ Perfect for a sip
*by J***G on January 3, 2025*

I bought this because I run fitness races (Deka/Hyrox) and my mouth gets incredibly dry, but I do not want to stop. I can keep this in the pocket of my shorts and pull it out for a sip - just enough to keep the dry mouth away. I have also frozen it to put in my sports bra on very hot short runs and it worked great. The small size is not ideal for everything, but it is perfect for what I need.
