Under Armour Women's ColdGear Authentics Compression Mock

I'm 5'3 and 150 lbs. UnderArmour runs notoriously small, so in order to feel like I can wear this without it being skin tight, I got the XL (allows me some "give" in the tummy area!). I adore these shirts. I have a white one in a crew beck that is a size L, but I wear it under my scrubs or under vests/ sweatshirts and it's perfect. They're pretty warm, lightly lined. Good for fall, winter, or spring since they're not heavy. Mock neck is cute. Also, I LOVE that they are a longer length! See photos of me in the XL. Sleeves do run long...that is a plus in my opinion and is easily fixed by rolling up sleeves.

I typically wear a medium but I tend to order a size up for Under Armour. I ordered this in a pinch because the trip I was leaving for in a few days was going to be colder than anticipated. The item was snug on me, to the point it was squeezing my neck. I still packed it (with tags on) thinking I’ll try it again when I get there. I tried it again and it was uncomfortable. I went to Bass Pro and they had Under Armour Cold Gear. For the same price + product, theirs fit perfectly and came with thumb holes. I let a larger friend wear the Under Armour purchased from Amazon hoping it would stretch a little and it didn’t (& it didn’t keep her warm). I love Under Armour but I wouldn’t recommend buying it from here.

I debated if I should write this review - so please consider this a simple warning that may or may NOT be correct. First, I do not have allergies. I do not have sensitive skin. I run daily, and was looking for an updated long sleeve running shirt. I love UA as well. All their stuff. I have UA shoes, their running pants are the BOMB and I run in their shorts in the summer. I am a fan. Ok - so the shirt. I returned it. I tried it on and it was too tight. Not a big deal, I actually assumed I would exchange the medium for a large (I am 5'7" and 140lbs). 10 min later, I broke out in hives on my back and in the creases of arms, my stomach. Not crazy scary hives, but ... blotchy, raised skin in places and it freaked me out. My husband gave me 2 Claritin and they went away about an hour later. The ONLY thing ... the ONLY think we could think of was this shirt. It's the only thing I touched or did differently. Even ate. Nothing was different about my routine. So ... I'm not a doctor and I could be wrong. I love UA, but I felt I should share in my comments. If you do like this shirt and it does fit you - please wash. My guess is that the dye or something in the packing ... or even the fabric. SOMETHING was on there and caused me to have this reaction. It spooked me for sure as I am not allergic and was a bit worried as you can imagine.

We had a cold snap where it was regularly in the teens during the day. As I walk my dog at least a mile every day, I decided that it was time to start taking layering more seriously. I'm 5'4", 116 lbs, 34A bra size xs-small in tops, and I ordered the small. It fits exactly like the picture, fitted but not too tight even the mock neck. It's incredibly soft on the inside and really warm. It's the perfect layering piece and I can really tell the difference when it's cold and I don't wear it. It' a bright navy and hasn't pilled or faded with washing and really frequent use. It's so fitted though that if you have any pudge or anything else it's gonna show, so if that bothers you take note. It doesn't bother me since I use it strictly for layering. I can't recommend this top enough.

I bought this shirt to wear under my work uniform. I work in a pharmacy with a drive-thru, so it can get freezing when at the window, but for security reasons I cannot wear a jacket or coat. This shirt fits well underneath my scrub top. It is not too tight, but I did order a size up on purpose to avoid that. I am 5'5 and 160lbs. I usually wear a Medium in tops, but I got this in a Large. It fits pretty well. I love the long sleeves that come to my thumb knuckle. Not the greatest fan of the collar as it's kind of too loose. But it keeps me warm. I still use a space heater by the window, but I'm much more comfortable wearing this as well. I don't know if I would purchase again because of the price. I might look into cheaper alternatives. But I definitely recommend this product if it's in your price range.

The product is what was expected. It runs a little small apparently and the seller Jiya, has a bad return/exchange policy of charging a re-stocking fee whether you want to return or exchange for a different size. Not flexible at all, given we are ordering clothes that may or may not always be he right fit. I will be sure not to order from this seller in the future.

Purchased for use during cold-weather runs this winter. I was a little warm after wearing it out in low 30s F with no other layers, so I am expecting it to work well when it drops down to the 20s.I'm 5'7" with long arms, and the sleeve length was long enough for me. I thought I would miss thumbholes, but in all likelihood I'll only be wearing this top when it's cold enough to require gloves.The top has a very straight silhouette - it's not cut for a female body. A size L is tight across the chest (32F), but sizing up to an XL would make the waist too loose on me, and I prefer form-fitting tops for running. The material does have a little stretch, but it's not a very flattering fit.Living in Chicago, I have to prioritize cost (bought on sale, I wouldn't pay full MSRP) and function (keeps me warm!) over fashion. If you have similar requirements, I recommend this product.

Read reviews and sized up from my usual XS to a S, very happy with the fit. This shirt is super warm and light, the inside is very soft. The day I got it I just wore it around because it was so cozy. When layered for a long run in cold weather (~10 degrees) stayed breathable and didn’t feel like it clung.

Warm and wicking. Wore for Tough Mudder in early May and was perfect for keeping my elbows for cuts from grit, warm from cold and wicks most moisture, so I don't feel like a soggy, drowned rat. Also wore for other things like hikes, bouldering, running (in the cold).

Love it so much I've ordered another. I wear it for curling when I need some insulation but not too warm when sweeping. I'm tall and a size 10/12, bought a medium and it fits fine. Warning though the sleeves are long and I've got long arms !! Particularly like the long body that stays tucked in and it washes well. Very pleased.

Great quality and very reasonable price. Very pleased with purchase. Not sure what it will be like in depths of winter but certainly keeping me snug on cold autumn mornings. I got a Medium and am a size 12 and it fits fine.

This top arrived promptly, and fits very snuggly. The sleeves are very long for me, and I wish that I had chosen a different neckline, as it is quite high for me, but that was my mistake. The lower neckline is much more comfortable. However, the top is great, very warm when warn with layers, but not too hot when the sun comes out, and wicks sweat well.

It doesn't state on the site that this product is anything other than new. I received the top today which I really like but there are make up marks on the inside neck so this is obviously a returned item. I think this is a bit unfair and the site should state why this is on sale.
