Underwear/Underpants — Litbuy Spreadsheet

Underwear and base layers are often overlooked in buying guides, but they are a steady category in the Litbuy spreadsheet. Boxers, briefs, and thermal base layers are included here. The buying criteria are different from outerwear: you want fabric breathability, waistband elasticity that holds shape, and tag placement that does not irritate. Because these items are worn directly against skin, material quality matters more than visual branding. The full catalog has options for daily wear and athletic use.
