The 42K ATLAS Evo soft flasks are flexible, compressible bottles for easily extracting liquids or gels. It is an indispensable accessory for correct, comfortable hydration in running and trail running.

These flexible bottles allow you to drink effortlessly and without worrying about spills, since their anti-drip valve only opens when the silicone mouthpiece is bitten.

It features a wide-opening mouth (4cm) so it can be refilled easily and it reduces its volume as you drink to prevent the liquid bouncing around inside it.

It adapts perfectly to trail running backpacks and it is a BPA-free product (Bisphenol A) for storing liquids safely for your health. The ATLAS Evo Soft Flask is available in two sizes (500ml / 17 fl oz and 350ml / 11.8 fl oz ) and also in two colours: red and blue.
