Let me start by saying this Under Armour pullover has become my go-to for transitional weather. The UA Tech fabric truly lives up to its promise - it's incredibly soft against the skin and manages moisture like a champ during my morning runs.

The fit is where things get interesting. I'm 5'4" with an athletic build (130lbs) and the Small fits me like a second skin - in a good way! It's snug without being restrictive, though I can see why some reviewers suggest sizing up if you prefer more room. The raglan sleeves allow for full range of motion, which I appreciate during yoga sessions.

Now about that thinness everyone mentions - yes, it's lightweight (I can literally roll it into my purse), but don't mistake this for being flimsy. Worn alone in air-conditioned spaces or as a base layer under my ski jacket, it provides just enough warmth without overheating me. Though fair warning - the lighter colors might be slightly sheer.

The ½ zip design is brilliant for temperature regulation. I constantly adjust it between my heated gym and chilly walk home. And after dozens of washes? Still looks brand new with zero pilling - that UA durability we all love.

Would I recommend it? Absolutely, if you want a technical, form-fitting layer rather than something cozy. Just size carefully based on your preferred fit!
