The Under Armour Men's Long Sleeve Shirt is a performance‑focused tee designed for active lifestyles.

The deal

It features moisture‑wicking fabric, a breathable mesh back panel, and a comfortable, tag‑free collar that keeps you cool and dry during workouts or everyday wear. The shirt’s classic cut and durable stitching make it a versatile staple for gym sessions, casual outings, and layered looks.

Why we like it

Right now, Under Armour is offering the shirt for just $13, down from its regular $33 price tag. That translates to a $20 savings, which is a substantial discount for a high‑quality athletic garment. The deal is unlocked by applying two promo codes – CHEATCODE and EXTRA20 – at checkout, ensuring you get the full reduction without any hidden fees.

Key features

This offer is perfect for fitness enthusiasts, runners, and anyone who values comfort and performance in their wardrobe. Whether you’re hitting the gym, going for a jog, or simply need a reliable long‑sleeve option for cooler days, the shirt’s moisture‑management and breathable design will keep you comfortable. Its sleek Under Armour branding also adds a sporty aesthetic that pairs well with shorts, joggers, or casual pants.

Who it's for

To take advantage of this promotion, visit the Under Armour website and add the Men’s Long Sleeve Shirt to your cart. At checkout, enter the promo codes CHEATCODE and EXTRA20 to apply the $20 discount.

Bottom line

Keep in mind that the promotion is limited to online orders and may be subject to inventory constraints. The discount applies only while supplies last, so act quickly to secure the shirt at the reduced price. No additional coupons or cashback tools are required – just the two promo codes provided.
