Perfect for winter

Originally posted on sweatybetty.com

Worn this constantly over the winter. Love it. Keeps me warm but not too warm. Keeps the wind out. I’ll get another one in a different colour

Soft and warm mid layer. Great fit, true to size. The purple is beautiful. So good I bought two!

I’ve been wearing the Therma Half Zip Midlayer for a few weeks now and it’s quickly become my go-to for cold weather runs. The 76% recycled fabric is soft, warm, and surprisingly breathable - perfect for layering or wearing solo. I love that it’s part of the HeatProtect collection; it keeps me comfortable in all kinds of weather without overheating. The slim fit is super flattering and the mesh back adds a nice touch of ventilation. The thumbholes and watch opening are game-changers, and the reflective details give me peace of mind when I’m out after dark. The length is also just right - not too short, not too long. Highly recommend if you're looking for a recycled, high-performance layer to keep you moving through winter!
