I have not used my soft flasks as of yet. I am making a bike trek in Aug. So I need something to pack light & flat when empty. I am hoping this is the ticket!!

Amazing space saver…

How wonderful to stash this little water wonder,& in a tight space , the more you drink, the smaller it becomes.. I was also happy to see that the silicon leaves no taste in the water. Perhaps, in future…? there could also be white ones, that would no heat as much in the sun. My other comment is that you have to me very careful, when threading the cap ON. It tends to go on crooked, & you don’t wanna strip the threading, so it is tricky to line up, straight. (Perhaps a little refinement on the start of screw on the cap is possible?). But it IS a wonderful water container….
