A great one! More colors, please!
I'll probably end up with one or two more of these because I like the fit and feel so much. I always need a long-sleeve top that will shield my arm tattoos from the sunlight while I'm out biking, running, and walking in hot temps. This is lightweight and does the job while feeling stylish! I actually own the older version of this top as well, and while I like both, I appreciate that they've stream-lined the design and shortened it a touch (do miss that pocket though!). I also love the color offerings. The Sage green and Amaranth tones are really modern. Why are so many outdoor apparel items either navy/black? For sizing stuff, I'm 5'7", 34B, 130 lbs, and I chose the XS in Amaranth (a maple red color). It's a flattering fit and length for my height, with the sleeves ending just at my wrist and length just below my hip bones but above the widest part of my hip.
Light as a feather weight
I was very impressed with this material - super light and soft. Wish I had chosen a smaller size - was roomier than expected. Quibble: I really wish REI wasn't stamped so prominently on the back lower corner of the t-shirt. For me, this reduced the versatility of this t which I was planning to also wear for general casual wear. Now, it's strictly relegated to 'athletic endeavors only.'
Comfortable and versatile
Great shirt for workouts, as well as running. Excellent for layering as there's not a lot of bulk. Soft and packs well. I was pleased to see a cool, clear color - magenta as an option, as REI's earthy, dusty colors look awful on me. Also glad that it is not tight - is a much more flattering, looser (but not baggy) fit - I am 5'5" and 120 lbs and the medium size is great.
feels good, smells not that good
I like the experience of wearing this shirt (lightweight) though it is a little less "soft" feeling as it is "tech" feeling. It looks pretty good in photos. Overall, I like it enough but the main issue is that it holds on to stink! I don't usually have a ton of BO (genetics), even when I'm backpacking, so it will remain a day-use/running shirt rather than a backpacking staple for me.
LOVE!
These are great fitting, lightweight tops. I now have four different colors and would not hesitate to buy more. I hope to see some bright colors so I can buy more! For reference, I am 5'1 and weigh 110 lbs. The XS fits me perfectly.
Returning Due to Label Visibility
I would 100% keep this if it wasn't for the REI label on the bottom/side of shirt which they conveniently barely show in the pictures (it's much more visible in person). Love the material and fit, but the label is not discreet enough for my taste. So frustrating when companies ruin great products with their labels.
Swiftland long sleeve running shirt. love it!
After reading the reviews, I decided I needed one or more of these shirts. I ordered a 2X as I have gained some weight and the XXL many companies have are just the larger size cut of the regular sized. The 2X is cut a little different, accommodating the 2X body. This was perfect! I love the shirt. I read that one person wore the shirt hiking for 5 days and that’s what I wanted. For hiking and just for every day shirt. One that I could rewear without having to wash after each wear. Well this shirt is it! It wicks moisture well, and I didn’t smell a thing on the shirt when removing it. Still as fresh looking too, after one all day wear. No wrinkles, nothing. The fit is wonderful. Nothing binding or restrictive. I might have gone with a 1X but wasn’t sure so I ordered the 2X. I’m in between the sizes and I think either would work, I do like how the 2X fits loosely. Will be my favorite walking, sprinting and hiking shirt! I like having cool long sleeves in summer to prevent sunburn. Thai shirt fits the bill. I’d say it’s my all time favorite shirt and a good thing it lasts long between washings, because I plan to wear it often!
Great Sun Shirt
Well vented and lightweight. I like this shirt nearly as much as my Patagonia Capilene Cool long sleeved shirts, and I like the price a lot better. It's a perfect sun shirt, washes well, and hasn't snagged or shrunk. I wear on all sorts of hiking and biking adventures.
It fits and is lightweight1
This T-shirt fits me well. I'm 5'4" and the shirt length isn't too long like the other REI long sleeve T-shirts. It skims the body and is not a tight fit. Also, the sleeves are a good length. Other REI long sleeve T-shirts' sleeves are too long.
My favorite running shirt
I was wearing this shirt when I was running and took a fall. All of my weight landed on my elbow. Although my skin needed six stitches, the shirt wasn't damaged in the least. And the blood stain washed out with just water. So in addition to being super comfortable, it can take a beating. Size small fits perfectly for me - 5'8" and 120 pounds. Highly recommend
