My new favorite base layer or main layer in warmer weather. Wore for a week straight with over 70 miles of walking, looked great and no smell!

great temp regulation and build quality, could use another color besides grey.............................................................

My new favorite layer for skiing. I have the reactiv base layer that on super cold days I will layer under this full zip. If it gets hot, I take it off and stuff it in my pack.

I was looking to replace my Patagonia R1, and this fleece beats it by a long shot. The fit is flattering and designed for women—not straight or clingy—and the temperature regulation is excellent. It’s thin but warm, perfect for layering under a puffy, and stylish enough to wear on its own. Great color options too (Graphite is a winner). Absolu...

This is a great layering piece. Flattering fit. Breathable and comfy. I’m usually between a S/XS. I chose XS and I wear a base layer underneath comfortably.

The Reactiv Grid Full Zip look great and looks stylish. The material is really soft. Just received as a gift so haven’t had a chance to wear it in action yet.

Nice, slim fit to wear under outer layers. I've used both as a base layer and midlayer. It keeps you warm, not sweaty. Another bonus- it doesn't get stinky smelling. Love that on longer trips. It's a bit pricey, but lives up to all the listed features. It's become one of my go-tos for active travel.

This jacket is a fantastic layering piece or used alone. I mostly wear it under my Kuhl The One Vest or under a leather jacket. It’s thin but warm and breathable. I’m 5’7” and 145 pounds and the medium fits perfectly. Wish there were more colors!

I love this layer. Perfect for chilly mornings and looks good enough to wear into town. I'm going to get another one in a different color.

Perfect for layering under a lighter ski jacket or for other outdoor pursuits that start of cold and end up sweaty!
