Product Overview
A warmer cold-weather outfit starts with the layer beneath your trousers. Rothco Extra Heavyweight Thermal Knit Bottoms use 9 oz, 100% cotton construction to add a substantial thermal layer, with soft fabric against the skin and cuffed ankles that help keep the legs in place.
Heavyweight Cotton for Cold-Weather Layering
These thermal underwear bottoms are intended to provide extra warmth under your regular clothing. The heavyweight knit makes them worth considering for chilly airsoft days, outdoor work, or time around camp when lightweight underwear is not enough. Cotton's soft, breathable feel also makes them comfortable for relaxed wear indoors, without needing to add an outer pair of trousers.
The cotton is preshrunk, which helps reduce the fabric's tendency to shrink after washing. That is useful for a garment you will wear beneath other layers, where maintaining a comfortable fit matters. Preshrinking is not a substitute for choosing the right size: consider how the bottoms will fit beneath your usual field trousers or everyday pants, particularly if those outer garments already fit closely.
Cuffed Ankles Keep the Lower Legs Contained
The ankle cuffs give the bottoms a snug finish at the lower leg, helping limit movement as you walk, bend, or pull on an outer layer. For an airsoft loadout, that means a thermal layer that stays more neatly contained beneath your trousers rather than leaving loose fabric around the ankles.
