I bought the black size L for running in cold weather. I normally love SW products.. However I was really disappointed with the quality of the material - it is almost 'teflon' like. Yes it is warm - but the material and quality do not feel good. Originally posted on www.sweatybetty.com

Warm and breathable to run in. Agree it's a little on short side (I'm 5'10) but still covers tops of my leggings so I just tucked it in to keep the draft out. Originally posted on www.sweatybetty.com

The Therma Boost Running Half Zip has such a soft warm inner lining! The colour is very flattering on. The item comes fairly short in the body which is perfect for people with petite proportions. I love the thumb holes too! I would definitely recommend this item! Originally posted on www.sweatybetty.com

Great mid layer for skiing and a lovely colour too. Originally posted on www.sweatybetty.com
