Under Armour HeatGear Armour Leggings - Lightweight (Style BJTM)

Our review of the Under Armour HeatGear Armour Leggings finds them best suited to athletes who need a true second-skin baselayer for high-movement training and cooler weather runs. The single biggest reason to buy is the super-light HeatGear fabric that balances coverage with minimal weight, giving a snug, ultra-tight compression fit that stays in place during grappling, running, or layered workouts. The leggings wick sweat and dry fast, and the updated gusset and ergonomic seam placement make them comfortable for long sessions.

Key Features

• Super-light HeatGear: Provides substantial coverage without adding bulk so users can layer or wear alone in mild to cool temperatures.
• Strategic mesh panels: Targeted ventilation helps regulate temperature during high-exertion training and reduces trapped heat in key zones.
• Fast wicking material: Fabric moves sweat away from the skin and dries quickly, keeping the wearer more comfortable during long workouts.
• Ergonomic seam placement: Seams are routed away from high-abrasion areas to reduce chafing and extend garment lifespan.
• Wide exposed waistband: The elastic waistband with wordmark detail offers a secure fit and simple pull-on convenience without digging in.
• Updated gusset and pocket: Gusset redesign improves mobility and comfort while a drop-in Strength PocketTM adds practical storage on the right side.

Who It's For

The HeatGear Armour Leggings are ideal for athletes doing high-mobility sports such as jujitsu, wrestling, or functional training who want an ultra-tight compression layer that moves with them. They work well as a baselayer for colder workouts around 40-50 F, and for people who value breathability from mesh panels while still retaining warmth.

Shoppers who need a relaxed fit or prefer looser training pants should look elsewhere, and those who expect heavy-duty, abrasion-proof fabric for constant outdoor use may find mixed durability reports; careful laundering and inspection after intense use are advised.
