"Haven't worn yet as it hasn't been too color but from a fit perspective it's great. Size small works for my 28" waist and broad (typically a size medium in other brands) shoulders."
"I bought this thinking, what the heck, it’s worth a try. I like the mauve color and the quarter zip. My other base layers are either full zip or none. I wasn’t expecting it to become the base layer I reach for every time. Even if I think it might be overkill, it still finds its way into my pack. It’s warm, yet thin and lightweight. I tend to wear a form fitting base layer underneath my removable layers. This quarter zip is the one I reach for the most to go over my next-to-skin layer. Great temp control, comfortable, thumb holes are awesome for adding/removing other layers or messing with gloves. It’s soft too."
"I love this baselayer. It is the perfect thickness and warm! It also fits perfectly."
"I love the fit, technology and color. My favorite base layer for long days snowboarding"
