Good quality close fitting thermal layering
Good quality layering top, serves as a decent baselayer. Comfortable to wear all day, good wicking properties, doesn't snag or catch under the armpit. Washes well and air dries on a hangar same day, no need to tumble dry (although not had any problems tumble drying). Fabric doesn't snag and no loose threads. Usual Pentagon quality. Be aware that this is a CLOSE fitting top - like a compression layer - so go a size up, I initially ordered a Large but had to exchange for an X-Large size (top marks to HH for ease of return and exchange!)
