AK pride and quick-to-dry!

I love being able to wear an Alaskan-made shirt! I run hot (and sweaty) even in the winter so I really appreciate how quickly this fabric dries. Thanks for a great product!

Great long sleeve shirt

Fit is amazing and it's comfortable too! Highly recommended for any outdoor adventure. Exclusively worn on extended camping trips with no smell because of the silver content : )
