Shirt feels a bit snug

This is a very thin shirt but not in a really bad way, it is great for the gym/travel/warm weather. Fits great and feels good on the skin, I am interested to see how it holds up over time, so far I am loving it!

This Smartwool Active Ultralite Short Sleeve is hands-down the most comfortable shirt I've ever worn. It's incredibly lightweight and breathable it legitimately feels like I'm almost not wearing a shirt at all. The fabric is so airy and soft against the skin, yet it wicks moisture perfectly and keeps me cool during any activity in the Phoenix heat. The merino properties are game-changing: anti-microbial so it stays fresh for multiple wears without needing a wash ideal for living in the hot Arizona desert where laundry piles up fast. It keeps you cool when you need it and warm when you need it, making it perfect for variable desert temps. I bought a size up just in case it would shrink (merino wool is known for that), but I've washed it multiple times exactly as the label says (cold wash, hang dry), and it hasn't shrunk, stretched, or lost its shape one bit holds up like a champ. I'm in the process of switching out all my shirts for merino wool ones like this for exactly those reasons. I snagged it on a random sale price, which made it a steal, but at full retail it's a bit steep for me right now, so I'll treasure this one and hopefully grab more when I can. If you're looking for a merino blend tee that disappears on your body while performing flawlessly, this is it. Highly recommend!

Bought this in xl expecting a bit of shrink. I normally wear L. I washed it once now it is way to small. I washed in on cold and dried it on no heat I was expecting a bit of shirk but now it cuts into my armpits and when lift my arms above my head it pulls way up showing my stomach. Not a fan!
