Thanks for such a cool shirt

Hope this helps people understand that this shirt is amazingly cool. Somewhere between a jacket and a shirt but way hipper and better looking than any old Jack-shirt that I had in the past. The shirt is so lightweight that I feel that I m in a futuristic world of clothing. No need for a jacket for going to town, but plenty soft and not too hot when sitting inside. Love the light green color.

Great shirt/jacket

I did not realize when i ordered this shirt that the material would be thick and super soft, really digging this different type of snap shirt. Hope you have some more colors coming out because I'd be in for a second!

Unique and cool shirt

Modern. Cool. Comfortable. Warm. Light. Seems to be standard of all the items I have from Beringia. But this shirt is very different as I have never seen or worn anything like it. Huge Fan - J.G. - Toronto.
