Water Bottle Foam Roller
Brilliant idea! Lightweight, portable and does a good job rolling out the muscles post activity. Also got more as gifts for my hiking friends.
Sorry the product has not arrived yet I cannot view it.
I've been pretty happy with my bottle roller. I've used it on a few hut-to-hut trips to roll out my quads and calves after long days of hiking/climbing/skiing. It is a little hard to get the roller on and off at the beginning, especially with a hard plastic Nalgene, but it gets easier over time.
I made a video about how to get the Bottle Roller off the Nalgene. It's available on our public Facebook page (you do not need a Facebook account to view). https://www.facebook.com/reel/1539846910110328
