not true to size

terrible fit.. i believed your true to fit feature and i felt and looked like a sausage in this shirt. Returning this plus 2 others.....Absolutely no way i could wear this shirt!!!! So disappointed in UA.....

Good shirt

I'm an active 40 year old so I own alot of similar shirts. I found this to be bigger than I thought it would be but that works for me. I like the way it looks and it's comfortable

Looks Great Feels Great

I would purchase this again!!! Good fit and feel. Only downfall is that it needs more color options.

UA MK-1 Long Sleeve -- Comfortable

I have really enjoyed wearing this since I purchased it a few months ago. Very comfortable when wearing this casually, especially when the summer evenings can get very cool here in the San Francisco / Oakland area.

Great for older dad

About ten years ago he started wearing these when he was playing seniors' baseball. Kept the sun off his arms because of a history of skin cancers. He is now 83 and wears these under his shirts - even polo shirts -- every day. Admittedly it's an interesting fashion statement, but it serves his purposes well. First, he's now cold all the time, and he wears it snug like a second skin, usually in white. Keeps him warm without being too warm. Perfect for him, even in sunny California. Second, he has had many skin cancers on his arms and wants to keep them covered so as not to get more sun exposure. This does the trick. He four of five of these, and rotates through them wearing them everyday, even though he's mostly indoors now. He can't afford the sun exposure even through the windows.

Good Product

I wear these in the summer to protect from the sun. I’ve had skin cancer before and with there being a very high chance of getting it again, I want to protect myself. The vented material keeps you cool like you are wearing a short sleeve shirt. Since it’s a “fit” size you may want to order up one size if you like your clothes loose. My only compliant would be the need of more variety in colors. [This review was collected as part of a promotion.]

Fits great, super comfy.

Love this shirt on its own, or as an undershirt for a short sleeve Tee. Fits great without being too bulky in the body (size XXL). Very comfortable, will likely buy again. [This review was collected as part of a promotion.]

Quality Item

I've been using primarily Men's UA Raid Short Sleeve T-Shirt for my gym workouts. This is in line with the same comfort and quality in long sleeve. Just what I was looking for. [This review was collected as part of a promotion.]

UA long sleeves are really neat & this one is top notch.

Comfortable, stylish, functional, versatile & durable. I am thankful for all my UA sport clothes. [This review was collected as part of a promotion.]

Very happy

Great shirt. Very comfortable on a run or just kicking back. [This review was collected as part of a promotion.]
