I'm 5'7", 125lb lean and got the Medium thinking it would be nice and loosey goosey on me. Either this shirt runs small or the gains from the gym are catching up to me (doubtful) but this shirt was surprisingly tight in the shoulders and upper arms. So be warned, if you're busty and broad (I'm not) you might want to skip this shirt altogether, not sure that sizing up will work this time around. The fabric is not your typical polyester sun shirt, it's very much a buttery-soft cotton-esque fabric which will be interesting to see how it actually Performs in the sun and spray (you know, if you actually wear it for Fishing). Arm length is great on my size and the concealed thumb holes are thoughtful. This shirt will actually keep the backs of your hands safe from the sunbeams. Extra points that it's cropped slightly and not overly long.

color is great, fit is great, and I love how they've altered the thumb hole approach most sun hoodies have. On most hoodies, thumb holes are in the seam along the wrist, and that shortens the sleeve length, so the thumb hole strangles my thumb (I have long arms). This shirt has thumb loops along the end of the sleeve. So much more comfortable! I also like the overlapping lower sides of the hood; nice coverage without being too tight around the neck.

Comfortable, looks and fits great. I wear as sun protection and casual sports.

As other reviewers advised this does run small. I am always a size small in Columbia but purchased a medium and it fits like a small. Recommend sizing up. Otherwise great purchase for a versatile piece that I will use as a base layer in cooler weather and a sun shield/primary layer in the summer. Fabric is soft and more like a regular tee in look and feel than most summer PFG shirts. Still Omni-wick.

I've had this for a month. I really like it, but it is tight across the chest, so much so that I sadly have to give it away after only wearing it briefly.

Love the fabric and long length of sleeves but shorter thru torso (dont have lots of extra fabric to tuck in)

Great pattern. Great material. Functional for my trail walks. I wear it when I need a light layer until the day warms up.

Very long sleeves. Nice color. Comfy material
