Under Armour UA Challenger Midlayer - Grey

The midlayer is made of polyester, featuring a smooth tricot knit exterior and a brushed interior.

While the brushed interior provides warmth, it's designed as a performance layer. For very cold weather, it's best used as a mid-layer over a base layer and under a heavier outer jacket.

Avoid using fabric softeners and excessive detergent when washing. These can reduce the fabric's ability to wick sweat effectively.

Yes, its lightweight, comfortable, and moisture-wicking properties make it suitable for a range of athletic activities like running, training, and general fitness, as well as casual wear.

The thumbholes help to keep the sleeves securely in place during movement and provide a bit of extra coverage and warmth for the hands.

Machine wash cold with like colors, use non-chlorine bleach if needed, tumble dry low, and do not iron or use fabric softeners.

Ensure you are not using fabric softeners during washing, as they can clog the fabric's performance fibers. Wash with a mild detergent and rinse thoroughly.

This is a standard feature for sleeve security. If it feels consistently too tight, consider trying a larger size or a different Under Armour style without thumbholes.

Check for any fabric caught in the zipper track. Gently try to move the zipper back and forth. Avoid forcing it.
