Under Armour NEOLAST HeatGear Long Sleeve Top - Black - M - Slim

NEOLAST is an innovative fiber technology used by Under Armour, designed to provide powerful durability and comfort, especially in cold-weather gear.

Machine wash cold with like colors. Tumble dry low. Do not use bleach, iron, or fabric softeners.

This top is specifically designed as a HeatGear baselayer for cold conditions. While it wicks moisture, it may be too warm for very hot weather.

HeatGear is Under Armour's original baselayer technology, designed to keep athletes cool, dry, and light. It's engineered for temperatures ranging from warm to very hot.

While designed as a baselayer, it can be worn on its own in cooler conditions. Its slim fit also makes it ideal for layering under jackets or other athletic wear.

This specific variant has a 'Slim' fit, meaning it's cut close to the body to support active movement without excess fabric.

This top features a mock neck collar, which offers coverage around the neck without being as high as a full turtleneck.

Ensure you have selected the correct size. This is a slim-fit garment; consider sizing up if a looser fit is preferred. Verify that seams are not causing irritation.

Make sure the garment is not excessively layered over other non-wicking materials. Check care instructions to ensure fabric softeners were not used during washing, as they can reduce performance.

The ergonomic seam placement is designed to minimize this. Ensure the garment is worn correctly with the seams aligned as intended. If irritation persists, consider alternative fits or styles.
