The Terramar Men’s 3.0 Ecolator TR Crew is a heavyweight temperature-regulating base layer designed to move moisture away from your body during intense cold-weather workouts so you stay as comfortable as possible.
The TR stands for thermoregulation, Terramar’s shorthand that means you’ll stay comfortable in a variety of conditions. With dual surface knitting that incorporates high loft grid channels in the textured fleece that is also brushed soft for warmth, the breathability of the 3.0 Ecolator TR Crew is enhanced with layering in mind. Micro polyester fabric with antimicrobial properties and all flat seam construction allow the 3.0 Ecolator TR Crew to serve as an odor-controlling, low-profile base layer in colder weather or a stand-alone layer in cool temperatures. The UPF rating of 50+ offers good sun protection. And the sleeves feature thumbholes to keep hands a bit more protected, as well.

Real Customer Reviews
- Excellent piece of gear!
Likes: Very happy with this, it breathes well and dries quickly. It's warm, and similar to the military waffle tops but softer inside.
Dislikes: None. Happy with this one.
- Lightweight and warm
Likes: I have two of these and they are my go to if I'm going to be in some serious cold weather and want to layer up. For how much insulation they add they are quite lightweight. Used this on summit night on Kilimanjaro.
Dislikes: After washing a few times the material seems to break apart a bit.
- I think this is a well made very heavy base layer. I have long arms and it was a little to short.
Likes: Very heavy and warm.
Dislikes: Arms a little short for me.
