I have a number of 'sun shirts' but none this lightweight and breathable. The blue denim color is lovely. The fit is perfect for me with longish arms--great thumbholes) and longish in the body (I am long in the torso). I can see I will get good use from this as a biking top alone and then under a vest and, later, jackets for biking, running, walking the dog and 'life' in general.

I bought this for spring skiing and I think it will be perfect. Very lightweight and comfortable, not tight. Will be good sun protection while not being hot.

I purchased this a bit large as it was the only size and glad I did. No sunburn in Moab for a week in June. Especially like how it covers the back of the hands. Was comfortable in the heat and did not block sweat evaporation. Much more comfortable than the tighter knit sun protection. Crossing my fingers that it will last as so very light weight. My prior spf shirt is about 2000 vintage REI and relegated to long river or backpack trips now. Bought more for my daughter and a friend.

I wore this hiking the Narrows at Zion National Park a couple weeks ago. It was the perfect layer because it staved off the slightly cool temps when we were starting and kept the sun off me when it hit mid-day. There are a set of zipper pockets in the front which is nice-- since the shirt is so lightweight though, it looked a little funny holding my phone there, but it was one of those hikes you didn't care. Overall I love this shirt and it's quality and kind of everything about it.

I did start to get a just a touch warm when the sun was on me, but I bet the airflow while riding a bike would negate that slight difficulty.

I loved the green/blue color that I ordered-- it's a more muted color compared to some athleticwear these days, but still enough color to not be boring.

This shirt is just so good! Lightweight, versatile, perfect for desert riding or a day at the beach. It’s well made and the blue/green color is so nice. My only gripe (really a tiny gripe!) would be the trim fabric on the thumb hole and wrist. This material is already starting to pill, which kind of detracts from the shirts nice, clean look.
