TD Base Layer Long Underwear | Merino Bamboo Tactical Base Layer Bottom Second Skin Performance. Built for Every Condition. The TD Base Layer Long Underwear is built to handle cold mornings, long missions, and everything in between. Designed as a true tactical base layer bottom, it combines the natural performance of merino wool with the breathability and softness of bamboo for all-season adaptability. Constructed from a 200gsm merino bamboo blend, this layer regulates temperature, wicks moisture, and resists odor while staying comfortable against the skin. It keeps you warm when it is cold, cool when it heats up, and dry through high-output movement. Built for movement, it features a gusseted crotch, ergonomic front panel, and wrap-around leg construction to eliminate restriction and reduce friction. The plush elastic waistband and flatlock seams ensure all-day comfort under kit, while the flip-top fly provides quick access when needed.
