ReebokMen's Long Sleeve Shirt - Performance Base Layer Compression Shirt for Men - Active Lightweight Men's Shirt (S-XL)

Thin , lite weight, comfortable. Helps keep me warm. Worth it.

This would be classified as a "lightweight" base layer. I don't know why base layers are no longer identified as light, mid, or heavy weight anymore but makes it harder to decide what to buy. It fits snugly but has a lot of stretch, doesn't feel uncomfortable and I'm one who doesn't like tight-fitting clothing. Has a satiny fabric, so really works well under something like wool. I really like the pattern, is nice to wear just as an everyday shirt as long as you have a flat belly, otherwise it would look ridiculous so don't do that please we don't want to see that.

These fit really well under regular pants and shirts. Really provide that extra bit of warmth I need after moving to Kansas from Florida.

I use it when weather is a bit chilly, but now I even sleep in it. Not heavy, but warm without getting hot you have to take it off.

Excelente producto. Lo uso como térmico o para correr. El desempeño es espectacular. Muy cálido y comodo cuando se requiere en clima fresco y/o frío. Y además lo uso de manera cotidiana. Se siente suena y cómodo. Una una excepcional.

This is my go to base layer

The fit is good and the quality also seems decent but the material is much thinner than expected and doesn't seem to provide much warmth.

I bought a couple of these shirts a year ago and they are great base layers. The quality is very good. I would certainly purchase this shirt again.
