Learn how to layer under a hardshell for wet alpine climbs. Build a system that keeps you dry on the approach and warm on the summit with the Sender GTX Performance Jacket.
Quick answer
For wet alpine climbing, wear a thin moisture-wicking base layer, a breathable midlayer you can remove on the climb, and the Sender GTX Performance Jacket as your waterproof outer shell. Adjust layers at transitions before you sweat or chill.
Why the shell is only half the system
A waterproof shell keeps rain and snow out, but it also traps heat and vapor. The layers underneath manage moisture and warmth so the shell can do its job. If your base layer holds sweat or your midlayer is too warm for the approach, you will feel clammy even in a Gore-Tex jacket.
The Sender GTX Performance Jacket uses a Gore-Tex ePE membrane and a thick, robust outer fabric. That combination is built for exposed alpine days, but it still needs a layering plan that matches your output level.
When to choose a different shell
The Sender GTX is designed for ski tours and freeride days, with a focus on deep powder and exposed lines. For fast, dry alpine rock climbs in warm weather, a lighter wind shell may be more comfortable. For wet weather climbing where you expect sustained rain or snow, the Sender GTX's waterproof protection is the right call.
Layering steps for wet weather
- Start with a thin, wicking base layer: Choose a synthetic or merino base layer that fits close to the skin and dries quickly. Avoid cotton, which holds moisture and cools you down when wet. Checkpoint: if your base layer feels damp before you start, change it.
- Add a breathable midlayer you can remove: Pick a fleece or lightweight synthetic puffy that fits under the Sender GTX without compressing. You should be able to take it off and stow it without removing your shell. Checkpoint: test your range of motion with the midlayer on before you leave the trailhead.
- Put on the Sender GTX Performance Jacket as your outer shell: Adjust the hood and cuffs to seal out weather, but don't cinch so tight that you trap sweat. Vent with pit zips if you start to overheat on the climb. Checkpoint: if you feel clammy inside, open vents or remove the midlayer before you get wet from sweat.
- Manage layers at transitions: Before a long belay or a summit push, add your midlayer back if you feel chilled. Before a steep approach, remove it to avoid overheating. Make these changes before you start sweating or shivering. Checkpoint: if you are about to sweat, remove a layer; if you are about to shiver, add one.
