My favorite shirt hands down. The most comfortable shirt I've ever had. I'm amazed at how well it regulates my temperature, cool in the summer and warm in the winter. Keeps me comfortable in western WA. Probably the most versatile product First Lite has. I love it.

Awesome base layer. I own both the Fuse Quarter Zip and Fuse Crew and have been extremely impressed with their performance and versatility.

I ordered this after a few colder than expected days in early archery deer season. It has quickly become my new go to piece. It keeps me warm on the colder mornings. Doesn’t over heat me while hiking and even kept me cozy during an unexpected rainstorm with no rain gear. Going to order more soon. Wish this was in a hoody.

So disappointed in the next to skin comfort, will be returning. I have several of the &quote;older&quote; FL 100% merino base layers and LOVE them - both lightweight and mid-weights. Not this one. Maybe I have extra sensitive skin but to me this has an itchier and less comfortable overall feel that made me sad. It would appear the addition of the synthetic blend just doesn't work for me.

Works as advertised, keeps you warm and dry on those mid-morning hikes and cool once the sun is overhead. More fade-proof than previous products.
