Size Chart

The Thermolator 2.0 Half-Zip Top is the ideal piece for all day warmth and comfort while being out in the elements. This versatile piece features an ultra-soft, midweight fabric utilizing our ClimaSense Thermoregulation Technology that automatically adjusts to your body temperature. It does this by trapping air to maintain warmth when your body starts to cool down. When your aerobic activity increases and your skin temperature rises, the fabric allows moisture vapor to escape to maintain comfort.

Whether skiing, mountaineering, fat biking, snowshoeing or winter running, Thermolator is functional performance at its best! The Men’s Thermolator 2.0 Crew Neck Top goes perfectly with the Men’s Thermolator 2.0 Pant and other pieces from the Thermolator collection.

2.0 Men's Thermolator® Performance Half Zip

Peter Allen
Thermostat or Performance Half Zip... GREAT

Fits perfectly, excellent layer, comfortable, lightweight and warm.
I’d donate away other stuff and buy more if I had not spent so much on them.
These are great!

Outstanding as usual

You guys set the standard in activewear baselayers and this does not disappoint. As usual quality construction and ventilation panels in all the right places. Buying another.

The Best

I purchased my first pair of Terramar base ware maybe five years ago. I've purchased other brands and now I always try to purchase Terramar first. They are very comfortable and efficient. The only thing wtih this Half Zip is I thought it would be a little thicker. So I may exchange it.
