Review on FITLY Soft Flask - 12 Oz (350 Ml) - Shrink As You Drink Soft Water Bottle For Hydration Pack - Folding Water Bottle Ideal For Running, Hiking, Cycling, Climbing & Rigorous Activity (FLASK350) by Nick Childs

This fits perfectly in my ski jacket goggle pocket. The bite valve works well and I like that I don’t have to take off my mittens to use it. I took off one star because of two pesky issues. That the cap seems to loosen easily. I ended up damp a few times. Customer Service suggested that I add a little oil around the threads to make a more water tight seal. Second, I’m an engineer and can’t figure out how to take the valve apart to clean it. I suggest the company give instructions or make a video on how to do it.
