Sunshield Half Zip

I purchased this item for active summer activities based on the first marketing line in the product description: "Pushing through fast-paced, sun-drenched days on the open trail is no sweat in the Sunshield... that will keep you feeling fresh in sweltering conditions". However, I found that this doesn't breathe well at all, traps heat and leads to a steamy/balmy feel, increasing my body temp/heart rate, leading to further sweating. I think if worn at sunny temps below 70 it would be a solid layer, but is way too warm for anything in the 80s+ in my opinion - assuming you're looking for an item that breathes. I wish I would have purchased another crater lake instead. It also rides up on the wrists and doesn't provide the sun protection a garment with thumbholes might. Aside from it not working out for the use I intended, it is a comfortable stretchy material and nice looking shirt. 2 stars because I felt it was marketed too heavily as an active layer for warm conditions and I don't think that's accurate.
