Dynamic Comfort
The FreeFloat A3 system allows the hipbelt, shoulder harnesses, and lower backpanel to adapt and conform to your body's unique shape. Patented FreeFloat hipbelt system and auto-rotating shoulder harnesses move and flex with your body's natural walking movements, delivering unrivaled comfort.

Adaptable Fit System
The ultimate in custom pack fit and available in three adjustable torso sizes, with fit ranges that overlap with one another, allowing you to size up or down to accommodate a smaller or larger body shape. The hipbelt padding also fully adjusts on all pack sizes to deliver refreshing, all-day comfort.

Aircushion Backpanel
The AirCushion backpanel is made from proprietary mesh with a 3D structure consisting of over 90% open-air. This next-generation padding provides true on-the-back breathability, eliminates pressure points, and has moisture-wicking cooling benefits.

Designed for women
The Gregory Deva Pro 80 is specifically designed for women to fit better. Women's packs utilize a more subtle curve in the shoulder harness for a better fit around the bust area, and the hip belt is desinged to have a steeper angle to match a women's geometry. Men's packs use a flatter hip belt angle and a more curved shoulder harness to properly fit the male skeletal structure.
