Camouflage Information: The M81 Urban Camouflage Pattern is a recoloration of the original M81 Woodland design. Though not officially adopted, it was notably used by the US Marine Corps during a 1994 urban operations training at Fort Benning. This pattern was part of a study evaluating various urban camouflage options, including disruptive and monotone designs. However, both the woodland and 3-color urban camo performed poorly in urban night conditions.
The M81 Urban Camo SS Rash Guard is a close-fitting base layer for no-gi BJJ and high-intensity training. Made from a lightweight, quick-drying knit, it provides a secure, supportive fit that tracks the body through grappling, drilling, and conditioning work. Moisture-wicking properties help manage sweat and reduce cling, so the fabric stays close to the skin without feeling heavy over longer sessions.
This version uses an M81 Urban camouflage variant, translating the classic Woodland geometry into a grayscale palette. Broad, leaf-like blocks in black, charcoal, and mid to light grey replace the original greens and browns, creating a pattern tuned to built-up, low-light, and mixed urban environments. On a training layer, the high-contrast shapes break up the torso while reading as a restrained, city-focused field pattern that works cleanly in the gym and outdoors. Short sleeves keep the forearms clear for grip and hand fighting, while the fitted cut is intended to minimize drag, reduce fabric shifting, and limit handholds during no-gi grappling. Flat, soft-feeling seams and a smooth interior help reduce friction against the skin.
Built from recycled performance fibers with UPF 50+ protection and certified to OEKO-TEX 100 and GRS standards, this rash guard functions as a reliable technical base layer for no-gi BJJ and other demanding training environments where mobility, coverage, and fabric performance are priorities.
