I love this shirt. I'm 5'9", 32D, ~145lbs, and I wear the small. It's classy enough to wear to work in my office; lightweight and cool enough to wear on trail. I like that it stretches, I like the buttons (I'm not into snaps, too many wardrobe malfunctions), I like that it reaches my wrists (I have a 5'7" wingspan), and I like that I feel good wearing it. The only thing that gets me is that the men's version has lots of color options and the women's is very limited. Maybe a nice sage green? Brick? Light blue? Dark pink? I'll be checking the website

My new favorite top for cool spring mornings or roll up the sleeves for hot afternoons. I have gotten so many compliments too from strangers. I purchased the white titanium one with the nifty pattern. I was worried about the buttons but I just leave the cuffs unbuttoned so it is easy to roll them up when in a hurry. It still smells good after quite a few days of sweating. Comfy loose fit!

More colours please

Not sure what all the griping about snap buttons is about, especially with a fabric so light. I've pulled snaps out on technical fabric like this, which sucks more than the inconvenience of making sure a button is pushed through. This review is left on first impressions, so I haven't tested it in hot or sunny conditions yet. Based on my first impressions, I wouldn't hesitate to wear this regardless of what activities I have planned for the day. Golfing, biking, hiking or hanging out at the beach, you'll look good doing it although you'll probably need a new one after a crash.

Almost perfect

Love the lightweight lose fit, I wear it mountain biking. Only bummer is you switched in this new version from snaps to buttons which is so frustrating when you need to quickly pull up your sleeves and you can't....i wouldn't say it is the most breathable material so not sure even though it is light I would use this material on hot days. Plus, even in a large size, it puckers across my chest (the snap version in the same large size didn't do this). But overall I love this top and the new pattern is cute!

Snaps, please

I love OR clothing but I agree with a previous reviewer that women's shirts should have snaps, not buttons. Large chested women like I am are constantly concerned with buttons coming undone.

Calls itself a sunshirt, barely sun protection

Bought this for thruhikes and travel, but find out it's actually only 30 SPF, which is on the verrrrry low end of any sunshirts.SPF 30 won't protect you for long. Most people looking for lightweight performance gear want items that will let them be outside for more than an hour at a time, especially for such a high cost.. Super disappointing, especially with the mediocre return situation (no stores to drop off at and no free returns). Would I recommend this? Only for people looking for a shirt for looks and coolness, rather than real usability. Think patio drinks with shade, not days out site-seeing or hiking.

Incredible shirt

I got this because I was looking for a lightweight long sleeve outdoor button up. This did not disappoint! It's so smooth, and cooling against your skin, and very lightweight! The fabric is really high quality and I find very flattering for my shape. Also, it's really a nice shirt so you can wear it indoors for other occasions. I haven't used it in super sunny weather yet so I can't attest to its UPF rating but I'm looking forward to trying it!

Why does men's have snaps but buttons for women's?

Why, why, why OR do you not treat women's clothing in a similar functional standard as men's? The Astroman long sleeve has snaps in the men's version but buttons in the women's - WHY??? Women like snaps too. Give me a break. Same with the zipper pocket versus regular open pocket for the women's. Do better for women.

Please don't stop making these!

I am late finding these but never too late! They are magical and beautiful all in the same! I had what I thought was similar from another company - they just went in the trash. Now because I am late finding them I won't know if they are seasonal, I am hoping I can buy them year round, hoping you do other colors but I bought them all in addition to all the colors in the weigh station style. Soft, technical, stretchy, cool, and beautiful. I will wear them on the range, hiking and everywhere else. Please don't stop making them!
