If you are between two sizes, go with the larger one. I wish I had. The sleeves are tight with just a tshirt on, def couldn't wear a long sleeve t or thermal under this comfortably. Also the sleeves are not sherpa lined, but I knew that before purchasing so no points lost there

The sleeves were nice and long, I have long arms. The body is really snug. I was hoping for something looser. I usually wear a 2 or 3X. I bought the 3X and am disappointed in the fit. It's fine for under other clothes but I was hoping I could wear it as the outer layer in milder weather.

I bought a size larger than normal, but it didn't help. I have a normal athletic build, but the cuffs are way too small and the biceps are way too loose. I clicked on the "Too small" button Amazon provides, but it would be more fair to describe it as an irregular fit. If you want a long sleeve undershirt to wear under outdoor gear and you know you'll never roll up your sleeves, your normal size might do. With a size too large, I found the upper arms bunching up uncomfortably under sweaters. The material itself is thin, soft and comfortable. I need to be able to roll up my sleeves, so I wouldn't buy again.

Bought this for my GF to go with the rest of her kryptek hunting gear lineup as a base layer. She wears it casually and shooting and likes how warm it is for a long sleeve shirt.

 However the sleeves are incredibly long. Even if I were to add thumb holes it would still be too long for that purpose, as of now she just doubles over the material around her wrist otherwise fitzwell

Really fits too snug and tight. Considering the fabric is a it heavy and thick, it won't be comfortable for warm weather. Also it is very tight around the shoulders and bust area. The cuffs for the arms are also not sized for average bodies. It would look best with flat-chest, slender forms. I did fit into the size I ordered, but it felt like one sneeze and the seams would bust. So the fitted cut does show off the form but also is restrictive in that i can't move comfortably in it.

I was not happy with the fit of this shirt.  It is very snug around the mid section and the sleeves are also quite tight.  For reference, I wear a M or L in Columbia active clothing and a L in Under Armour. I ordered this in an XL based on reviews and the size chart.  I would not feel comfortable wearing this for a run or to the gym.  Sent it back.

long narrow cloth would not even be able to wear it as a arm warmer much less get it over any pets head unless the pet was a miniature giraffe

Fits small through chest and armpits area on sleeves are tight. Shirt is long from neck opening to the bottom of the arm holes too.

I'd hoped for a better fit but the cut wasn't right for me. The sleeve length was good, and I have long arms, but it was too tight for me across the back. I also think the fabric would be a nightmare with pet hair. I'm returning it.

I'm 5'11" and 140 lbs.  I wear a medium in almost everything, but this was way too tight.  It might look cute on somebody shorter than me, but the sleeves weren't anywhere near long enough on me.

Disappointed. Sleeves are too short. Just past the elbows. For pretty big robes ( I wear small, my husband is medium) it looks strange, not warm and cozy

I'm 5'9, 145lbs, am a 36B  and wear a US size 6/8. After reading reviews, I sized up to a large, but it restricts my arm movement quite a bit.  It's very uncomfortable and tight across my chest.  It's long enough in the torso, but the sleeves are much shorter than a standard tee.  The top is cute and looks just as pictured.  I'm going to return and reorder in an XL and see how we do.

It's not a comfortable top. It's thick, the sleeves are really awkward and long. I had to roll them up. i even washed it and the material is still hard. It was too much of a hassle to return it.

The chest and arms fit fine, but mine has a body length that would fit someone 6'8" and I'm only 5'11".  Disappointed in that aspect but I wear it on cold days and keeps my behind warm too.  It was actually thicker Sherpa lining than I expected.

The fit was so disproportionate I have no idea how anyone is supposed to retain body heat in this. Save your money, there is another brand that is much better. I know this because I have a polypropylene top in coyote brown that fits perfectly and is super warm especially when you are active. The brand is called Wind Gap Knitwear. Try them out first. Then if you have tiny arms and a neck three times larger than that of the average human being, maybe this might be a viable option. Although, I've never had anything from Voodoo tactical really last very long without some sort of failing.

The sleeves are too long on these t-shirts. They can't be worn with polo shirts or other short sleeve shirts. I bought these because my other Hanes t-shirts seemed better than most in this regard, but was disappointing to see how this style turned out.

i thought it would be a long undershirt like a t shirt, but the sleeves became really tight towards the wrists.
