SoftFlask™ Speed 500ml 2-Pack

Bought these to replace the flasks that came with my vest and they fit way better in the front pockets. The pinch-welded bottom really does help them slide in without fighting the fabric. Two for the price is a nice bonus too.

I was a bit skeptical about compatibility with my pack, but these slide into the pockets effortlessly and stay secure even when full. The two-pack is perfect for back-to-back training days or sharing with a buddy.

The pinch-welded bottom on these makes them slide into my vest pockets way easier than my old flasks, no wrestling at all. I've used them on three long runs now and no leaks or weird plastic taste. The 500ml size is perfect for a two-hour effort.
