Under Armour Tech 6-inch Boxerjock features

The blend of stretchy polyester and elastane is incredibly soft and breathable, and the strategically placed mesh panel and flat-seamed pouch means they don’t chafe – even on hot runs over two hours. That’s helped by the one-piece design with no potentially irritating back or side seams. 

The waistband is soft but stays put without digging in, rolling up or slipping down. The thin material helps with sweat-wicking and quick drying. That’s a big help if you wind up having a coffee before you get the chance to change.

Length-wise, the legs drop to mid-quad level and the elastic cuffs stay in place so your dignity is safe for any high-up work. Durability is excellent, too. A single pair can take heavy usage – and months of trips through the wash – without losing shape or wearing thin.  

They come in five colors and six sizes from XS to XXL. Every bloke could benefit from having a few pairs of these lurking in their gym-gear draw. 

How do they compare to the best moisture-wicking underwear?

When comparing Under Armour’s Boxerjock with our top-rated pair of moisture-wicking underwear, the CXP Endurance XP, both offer excellent moisture-wicking and durability, but they cater to slightly different needs.

Under Armour’s briefs are perfect for versatile workouts like yoga and pilates, with a comfortable and breathable polyester-elastane blend, and a non-chafing design ideal for up to two-hour runs. They come in five colors and six sizes, providing a snug but not restrictive fit.

On the other hand, CXP Endurance XP offers more support and compression with a longer-leg design, ideal for high-intensity endurance sports like running and rugby. Made from a nylon-elastane blend, they’re lighter, provide more muscle support, and feature an ergonomic pouch and bonded seams for zero chafing. The standout feature is their multi-panel waistband, reducing abdominal pressure and offering superior stability with silicone grips during ultra runs. However, they are limited in color and size options.

Both are durable, with CXP enduring multiple marathon tests, but the choice depends on the level of support and activity type you need.
