The 42K ATLAS soft flask is a flexible, compressible bottle for easily extracting liquids or gels. It is an indispensable accessory for trail running or road runners who need to hydrate effortlessly and without worrying about spills, since its anti-drip valve only opens when the silicone mouthpiece is bitten. It reduces its volume as you drink, which prevents the liquid from bouncing around inside it. It adapts perfectly to trail running backpacks and it is free of PVC and BPA (Bisphenol A). The 42K ATLAS soft flask bottles are available in two sizes (500ml and 250ml) and also in two colours: red and blue.
