## Description

The FITLY Soft Flask is a lightweight, reusable hydration bottle for running and active outdoor use. Its flexible body shrinks as you drink to help reduce sloshing, bouncing and unnecessary bulk. Store it in a hand, pocket, running belt, compatible vest or backpack, then fold it down when empty. The silicone bite valve supports quick sips while moving, and the leak-resistant closure is designed for confident transport. Made from BPA-free and PVC-free TPU, the flask can be frozen and used for water, electrolyte drinks or energy gel. Choose the capacity and colour shown in the title for running, hiking, cycling, climbing, skiing and travel.

## 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.
