Have been through cheaper bladders that don’t last the distance due to design faults. The Solomon Bladder has and easy to open and clean design + a seal that requires no locking tabs that have broken on other models. The Solomon has an easy slide on top that seals and is also suitable in my Lowe Alpine backpack & UD running vest. Thanks BMRC!
Works well. Just didn’t lubricate the o-ring on my first run with the pack & it leaked down my back, which wasn’t unpleasant on the sweaty run!
