Under Armour HeatGear® Short Sleeve Mens - Grey - L

HeatGear® is Under Armour's original performance baselayer fabric. It's designed to be ultra-lightweight, breathable, and to wick sweat away from the body, keeping athletes cool and dry.

While HeatGear® is designed for regulating body temperature, it is primarily a moisture-wicking layer. For very cold weather, it's best used as a base layer beneath warmer insulating garments.

Yes, you can wear it as a standalone shirt, especially for training or workouts. However, its primary design is as a performance baselayer.

Refer to the Under Armour sizing chart for men's tops. Since this is a compression fit, it should feel snug. If you prefer a looser fit, consider sizing up.

This refers to a sleeve design that combines elements of a raglan sleeve (seam runs from underarm to collar) with a traditional set-in sleeve. It's engineered to provide enhanced freedom of movement and comfort, particularly around the shoulder area.

No, it is strongly recommended not to use fabric softeners. Softeners can clog the fabric's fibers, reducing its ability to wick moisture effectively and compromising its performance.

This is a compression fit designed for support. If it feels excessively tight, consider trying a size up. Ensure you are washing and drying according to care instructions, as improper care can affect fabric elasticity.

Check that the garment is clean and free from fabric softener residue, which can impede wicking. Ensure you are not layering too many non-wicking garments over it. Wash with like colors using a mild detergent and avoid fabric softeners.

The ergonomic design aims to minimize irritation. Ensure the garment is oriented correctly and that you are wearing it as intended. If irritation persists, ensure the size is correct and consider if a non-compression fit might be more suitable for your activity.
