Fits mature, busty figures
My husband swears by his REI Sahara shirts but the women's XL simply didn't fit -- as a woman "of a certain age", my figure is mature. Even though the XL fit was mostly OK, it was waaay too tight across the bustline and the pockets FAR too high (gravity is winning). I was highly dubious about ordering a 2X but it worked, and worked well. The 2X is not as tent-like as photos would suggest. While the pockets could easily be moved an inch lower, they still look OK. Best of all -- no pulling across the chest. I wore it over a short-sleeve top while hiking Zion's Narrows and was very comfortable. It held up to abrasive sandstone when worn as a single piece while canyoneering near Moab. Not only was I perfectly comfortable in the slots, the shirt still looks new. Great skin protection: no sunburn, abrasions, or insect bites. Cute, too. I typically wear an XL in tops -- but NOT in the Sahara shirt. For the reasons noted above, the 2X was a great fit.
Great shirt, poor fit
I bought this based on other reviews that it fit well for larger busts. The fabric, quality, and cut of the shirt are great, it was just a size small for me. I wear a 2X in just about everything and this was tight, didn't button across the chest, and was a bit shorter than I expected in the 2X. The lines of the shirt are great, in the right size it would be a great shirt. I will try sizing up I guess. Just wish plus size clothing was more consistent and didn't require so much trying and exchanging.
And no chest button pucker!
This shirt is great! Nice material against your skin and is a good shirt for fishing, kayaking, hiking. The sleeves can be rolled up. The length of the shirt and sleeves is also nice. I like light blue color too. I was concerned that the buttons would be stretched across the chest but they did a good job of making an plus size shirt and not a small size just bigger. If you know what I mean.
Poor fit...
REI has been shrinking their plus sizes...this shirt would get a five star review if the fit wasn't so off. The fit runs about a size smaller...that's too bad and very disappointing.
Flattering fit
Very comfortable shirt and the fit is very flattering. It has a nice stretch to it without being clingy. It also isn't noisy and dosen't make any weird swooshing sounds like another hiking type shirt I tried on. The peppercorn color is great and will work nicely for my needs of short trail hikes followed up by going into town without having to change clothes.
KEEPS ME COOL
Love the shirt--do not hike without it. I wear it open like a jacket with a tank under. Keeps me 'shaded' (I got the white), and while my hiking partners are slapping at mosquitos, I'm enjoying the view. It also keeps me from getting sunburned (at least so far).
Short
This shirt is short and very fitted. Disappointed and returned.
Excellent shirt
I bought this for field work. I liked the blue and bought the 2x, although I am usually an XL. It's too big in the body but actually looks fine, and the sleeves are long enough. No complaints
Roomy fit, sheer fabric
I bought a 2X, it fit comfortably through the arms and bust but was just a little too snug around the hip. The sleeves were a nice length. The white fabric was a little too sheer, and the chest pockets are unnecessary and unflattering.
Nice shirt for sun blocking comfort
I bought 2 for the sun blocking comfort, and the fit is great. However I can’t stand the synthetic feel on my skin in hot weather. Another issue is that I work in the forest preserves as a steward and the fabric is prone to picking up every thorn, bur, seed, and prickly branch. Not a smooth fabric. Spent an hour and a half pulling out beggars tick seeds the one and only time I wore this. So if you don’t mind synthetics, and you will wear this shirt far away from narrow trails and foliage, it will be comfortable, sweat wicking, and sun blocking.
