As with so many things in life, the inspiration for Choctaw Ridge came from an underwear box from the 1930s, an item that "represented an era when men put considerably more effort into their appearance", apparently going so far as to wear underwear. Helping bring things back to those halcyon days, Choc's initial undergarments are all hand-made, seriously detailed & seriously-er expensive, and include everything from v-neck tees, to long johns, to boxer-briefs, boxer-debriefs usually just being "Obviously you didn't complete the mission, because you're a pair of boxers". Here's how you'll be swaddled:
Uppers: Slim-fit v-/crew-necks are made from "buttery-soft featherweight Pima cotton" and modal jersey, while a "burly waffle-knit" and a cotton chambray are used in making Thermal Henleys, which would probably overheat the Boys of Summer.
Lowers: Also slim-fit and outfitted with Corozo buttons, briefs're made from a "sag-free fine rib Pima cotton/modal/lycra blend", while boxers are cut from lightweight Japanese linen & cotton and have a short inseam to prevent bunching, sure to distress Mr Tallywhacker Man.
Even Lowers: Those with chilly calves can opt for long johns made from the same material as the Henleys, or "lounge pants" built from a "tough yet soft" cotton chambray, and given an elastic waist in recognition of the fact they're for an era when men put considerable effort into expanding their appearance.
