"The HSA 800 Evo Hydration System is an update of the HSF AERO HC 800 with improved Garmin placement and a refined rear cap mechanism." - Profile Design. Allowing better sighting of your cycling computer, and easier refilling of the hydration system.
 
"The HSA 800 EVO has been designed to incorporate all the essential features required of an aerobar bottle system along with a couple of premium add-ons.
Flexible hose with bite valve and magnetic retention.
Direct Garmin mount / removable.
New mounting bracket with greater compatibility than previous models.
New cage with high retention.
Rear cap can be removed for easy cleaning.
Secure fill port lid to avoid splashing.
Additionally, the shape of the bottle has been designed to hide the cage from the wind. We worked to minimize frontal area wherever possible to avoid adding aero drag to your setup.
