Add more to the arsenal, or replace your aging flasks with a Nathan 3-Pack of 8 oz nutrition flasks with Race Cap; replacement flasks for the Nathan Speed 2R, 3R, and 4R as well as the Swift energy belt.
Comments: These are sold for gels but I LOVE them for water usage! Great that you can just squeeze and don't have to pull out the cap while you're running. I've purchased extras too because when you buy the belt originally it only comes with one bottle with the race cap. Careful though - I had a full one one the counter that fell off onto a wood floor and the top broke & cracked :( From: Lisa, Chicago, IL, USA
