TD Base Layer Long Sleeve Top | Merino Bamboo Performance Base Layer

Merino-Bamboo Performance Layer for Every Mission.

The TD Base Layer Long Sleeve Top is built to perform across every season, combining natural fibers with technical construction for a true all-season base layer. Made from a premium Merino wool and bamboo blend, this top regulates temperature, wicks moisture, and resists odor while staying incredibly soft against the skin.

The 200gsm fabric weight strikes the balance between warmth and breathability, making it ideal as a standalone performance shirt or as part of a full layering system. Merino wool manages heat and moisture, while bamboo adds breathability, softness, and natural antimicrobial properties to keep you comfortable during long wear.

Designed for movement, this base layer features underarm gussets, forward side seams, and wrapped shoulder seams to eliminate friction and allow unrestricted mobility under packs or kit. Thumbhole cuffs and stretch finishes keep everything in place when layering, while low-bulk flatlock seams prevent irritation.

If you are searching for a merino wool base layer, bamboo performance shirt, tactical base layer top, or moisture wicking long sleeve, this is built to perform in any environment.
