    The collapsible bottle is a great addition to the Ultraspire line. I’ve been using it since they came out. It fits easily in the front pockets of any of the packs. The bottle weighs close to nothing, so when empty, there is nothing heavy to carry along unnecessarily. And because it is so flexible, it conforms to whatever body shape you have. No annoying hard bottle against the chest.

    The one draw back is that it cannot stand up on your own. Although filling at aid stations is easy, the bottle has to be held until the screw top is back in place.

    I did find that if the straw is down against the bottom of the bottle, the bottle itself will get drawn up against the tub when sucking on it, preventing flow of fluid. The easy solution is to 1) Cut the bottom of the tube at an angle and 2) drill a few small holes along the tube. That way, if the bottom does get wedged against the side or bottom, fluid can still be drawn in through the other holes. This approach is used in cannulaes used in cardiac surgery and proves to be very effective.
