Our take on the Under Armour Heatgear Mock Long Sleeve Baselayer Men - White/Black

The Under Armour HeatGear Mock is a men's compression baselayer with a high mock collar and long sleeves, built for warm-weather training, running and gym work. Its HeatGear fabric is a polyester-elastane blend with roughly a fifth elastane, so it stretches hard and holds a tight, second-skin fit. The mock neck adds sun and wind coverage that a crew-neck baselayer does not give. Rivals like Nike Pro and 2XU offer similar compression tops, but few combine this stretch level with a high collar at Under Armour's usual build quality.

Pros
  • High elastane content gives strong stretch and a locked-in compression feel
  • HeatGear fabric wicks sweat and dries fast
  • Mock collar covers the neck from sun and chill
  • Flatlock seams reduce chafing under packs and straps
  • Wide size run from S to 3XL
Cons
  • Very tight skinny fit; size up if you dislike compression
  • White color shows sweat and dirt quickly
  • Mock collar can feel warm in peak heat
  • Thin fabric offers little warmth for cold weather

Questions and answers

How tight is the fit?
It is a compression baselayer with a skinny fit, so it sits tight against the skin. If you want a looser feel, go up one size.
Is it good for hot weather?
Yes. HeatGear is Under Armour's warm-weather line, and the fabric wicks sweat and dries fast. The mock collar adds warmth at the neck, so it suits cooler mornings or covered training.
Can I wear it on its own?
Yes, many wear it alone for runs and gym sessions. It is thin and fitted, so some prefer it under a tee or jersey.
How should I wash it?
Machine wash at 30 degrees. Avoid fabric softener and high heat, which break down the elastane and reduce stretch.
Does it come in other colors?
This listing is the white and black version. Under Armour makes the HeatGear Mock in several other colors, so check the range if white is not for you.
What sizes are available?
It runs from S to 3XL. Check the size chart, since the compression fit runs tight.
