Under Armour HeatGear Sleeveless T‑Shirt Men’s Compression Base Layer Vest

The Under Armour HeatGear Sleeveless T‑Shirt is a men’s compression base layer designed to sit next to the skin without weighing you down. Lightweight HeatGear fabric delivers a second‑skin fit that supports key muscle groups while remaining comfortable under work shirts, polos or teamwear. The material wicks sweat and dries quickly to help regulate your temperature in warm conditions.

The sleeveless construction keeps your shoulders free, ideal for overhead work, lifting and high‑intensity training. Flatlock seams and stretchy fabric reduce chafing and allow a full range of motion. Finished with Under Armour branding, it looks sharp worn on its own for training or layered under kit or workwear.

Available in multiple core colours and sizes S–XXL, the HeatGear Sleeveless T‑Shirt is a versatile base layer for work, sport and summer wear.
