Innerwear sits against the skin all day, so the yarn has to be soft, breathable and clean. Here is what to source.
Softness and cleanliness first
Fine combed cotton in the 30s–40s range is the mainstay — smooth, low-nep and gentle. Bamboo and modal add a silky, breathable, premium hand.
Comfort and fit
Innerwear is knit — soft single jersey, rib and interlock, usually with a little elastane for stretch. Even yarn knits cleanly with elastane and holds shape wash after wash.
Choosing yarn
Lead with combed cotton for value and comfort, bamboo/modal for premium ranges, and CVC where a little added durability helps. See hosiery yarn and size the order with our requirement calculator.
