As an ambassador for Terramar Sports, I've been able to get out in the winter months and continue training and racing without issue. This time around, I was fortunate enough to receive their Climasense 2.0 Thermolator Pant, 1/2 zip and mock shirt. Let me tell you, I really love my TXO 2.0 layers and my Terrmar SmartSilk layers, but the Climasense/thermolator set is top notch. Hands down, it's the best baselayer set I have in my repertoire.
I couldn't really tell you how cold this base layer set can withstand, but as a trail runner, this set is absolutely perfect for anything above 25, especially when you couple it together with some Terramar Smart Silk glove liners and a Terramar beanie. This base layer set moves with you and never bunches up. It's like a second skin almost. The sleeves of the mock and 1/2 zip have thumb holes. With these layers on, I've done runs in 30 degree weather without issue. I've yet to make it out in below 30 this season but I can tell you, I wouldn't hesitate to use my Thermolator layers. When I'm cold, these layers provide a warming effect and if I'm hot, they provide a cooling effect.
