Quick answer
Pack the Full Zip if you run hot, layer often, or want precise temperature control on the move. Choose the Pullover if you want a simpler, lighter layer for steady output and camp warmth.
Ventilation and temperature control on the move
The main difference is the zipper. The Full Zip has a full-length zipper, so you can open it wide during a climb and close it fast when you stop. The Pullover has a half-zip, which offers quick venting but less range. If your pace varies a lot or you switch between sun and shade, the Full Zip is easier to regulate without taking off your pack.
Layering and packability
A full zip lets you put the hoody on over a hat or helmet without pulling anything off, and you can open it while wearing a backpack hipbelt. A pullover usually feels simpler against the skin and has fewer parts to snag. Both use the same Octa fleece, so the warmth-to-weight story is similar; the choice comes down to how you manage heat and how often you adjust layers.
Weight and simplicity
The Pullover has less hardware, so it is the more minimal option if you rarely unzip fully. The Full Zip adds a full-length zipper for more control. Neither is a rain shell, and neither is insulated enough for freezing stops on its own. Think of both as active midlayers that breathe well and dry fast under a shell.
Trade-offs to weigh
- Ventilation range: Full Zip opens fully for maximum airflow; Pullover half-zip gives limited venting. If you overheat quickly on climbs, the Full Zip is easier to manage.
- Layering convenience: Full Zip goes on over hats and helmets without removal; Pullover requires pulling over your head. Choose Full Zip if you often adjust layers while wearing a pack or helmet.
- Simplicity and minimalism: Pullover has fewer parts and a cleaner feel; Full Zip adds zipper hardware. Pick Pullover if you want the simplest possible midlayer.
