Layer Up

The Smartwool Layer Up System: The Solution


Layering, Made Smarter
It’s pretty simple: when your gear works better, you can stay out longer.


Instead of looking at layers individually, we took a “system” approach–designing pieces that not only work independently, but together as well. Fitting together. Made for each other. Smart Layers that are more efficient, with less bulk. Layered together, Smartwool® products don’t bunch or restrict movement, so you can focus on the trail ahead and not your clothing.

When the weather calls for a second layer, Merino layered together is the best fiber for mountain athletes. In a recent, third party study, athletes who layered in Smartwool garments were cooler and more comfortable that layering in all synthetics.*

All percentages reference layering Smartwool base layers and midlayers versus 100% synthetic base layers and midlayers
