I have 9 of these shirts in most of the colors offered. I started off with one last year, a closeout in Tangerine that I liked enough to get a few more at the time, because as they say "cotton kills". I'm writing this review though on the three that I just got. These are a newer model that differs from the original in that they have a regular pocket flap, not the tapered ones the earlier version of this shirt had.
But what really sets these new versions apart is the fabric. First, Backcountry needs better graphics on their website. The Tank and Trail colors are not done justice by the photos as they are much richer and earthy in person. Next the newer fabric is softer with a nice "hand" and on the inside face is a micro mesh texture that ventilates and keeps the fabric from sticking to your skin. Off and on I've been into nice threads since I was 12, made my living in the "needle trade" for 18 years and have to say these newer made in India, Columbia SilverRidge II shirts blew my mind!I wore one the other day in the sun when the temp was in the 90s and was comfortable. I have not yet worn this new version in the bush to see how they hold up.
I'll report back if they snag or run easily or exhibit any other negative wear characteristics.
