You get what you pay for
- Familiarity: I've used it once or twice and have initial impressions
- Fit: True to size
- Size Bought: M
I should preface this by saying that I'm forever stuck between a medium and a large in almost all brands. The Medium size has a good fit in the chest/body, but feels very narrow in the shoulders/armpits, very short in sleeve length (maybe that's so it'll fit under long-sleeve jerseys? I don't know). If I sized up to a Large, I feel like the body would start to get baggy but the shoulder width and sleeve length might be more appropriate. Slim cut, but not fitted, and not very stretchy material.
Fabric is pretty lightweight, and reasonably breathable. Wicks sweat just okay, I would say a good temperature range for this base layer is 60-75*F (16-24*C). Definitely not recommended for properly chilly conditions. My main concern is durability. I have noticed a significant amount of pilling beginning on one sleeve after one use and a gentle (hand) wash. Time will tell.
I wish I could say this was a steal at $35 that works as well as fancy expensive base layers, but alas it isn't so.
