HSA 800 EVO Hydration System

What Our Gearhead® Experts Are Saying:

"The HSA 800 EVO is the most complete BTA hydration system I've used. The magnetic bite valve retention keeps the straw exactly where I need it, the rear cap comes off for easy cleaning, and the removable Garmin mount is a feature I use on every build. The offset mount placement is a genuine improvement for aerobars that would otherwise push the bottle too far forward to reach comfortably."

Staying on top of hydration during a triathlon or time trial means keeping water accessible without breaking position, and the Profile Design HSA 800 EVO Hydration System is built around exactly that. The 800ml BPA-free bottle sits between the arms where it's easiest to reach, with a flexible hose, magnetic bite valve retention, and a secure fill port that prevents splashing on the move. A removable Garmin mount, high-retention cage, and a bottle shape designed to hide the cage from the wind round out a system where every detail has been considered.
