    1. Great shirts at full price Rating

      Posted by Patrick Camp on 26th Apr 2016

      Another well-made product from Allen. I'm not sure why these went on sale? They are comparable to the $40+ base layer shirts Cabela's sells - and the Cabela's shirts don't have the UPF protection. Keep it up, guys.

      The good folks at Allen inadvertly sent two sunivanna shirts instead of one each spectrum and sunivanna. I have not called yet to correct this. The shipping was excellent however.

      Great fit. Quality materials.

    4. Great Mid-weight shirt Rating

      Posted by @North2theFuture on 10th Sep 2015

      This shirt is a great mid-weight piece that is versatile and comfortable. It is a looser fitting shirt, that is thick enough for mid-weight or outwear warmth, but not too heavy as to overheat you as the sun comes out and the day warms up. Perfect for those late-spring, early-fall days when you know you wont wear the shirt all day, but you need to start or end with a layer.

      It is 100% poly, so it feels synthetic - but the cut, color, and stitching are all great. A really versatile top.
