Reviews

I love this shirt

"This is a great light weight shirt. Cool enough that you can roll up the sleeves on a nice day and be comfortable and enough coverage that when it cools off at night your not cold. Seems fairly durable. But it is thin Marino wool so I wouldn’t trek through heavy brush."

— Ryan T. (5/5)

Kuiu ultra merino 145 zip-T hunting shirt

"As always an amazing product. Fast shipping"

— Terry G. (5/5)

Nice mid layer for active wear.

"Very nice mid layer, breathes well, good zipper, wish there was thumb holes in sleeve, fit is loos which I like. Imbetween sizing and followed recommendations to size up. Find my xl quite loose on arms other than that it is good. If I was to purchase again I would go with proper sizing I think this shirt fits true loose at proper sizing but then again ni hate a tight restrictive shirt so perhaps I made the right decision."

— Tim C. (4/5)
