CEDR 100% Natural Fiber Boxers
A range of 100% natural-fiber boxers - organic cotton, merino wool, mulberry silk, or linen - with natural-rubber waistbands and no synthetics. The go-to for non-cotton, zero-synthetic options. Natural rubber is a latex.
The verdict: Plastic-free
Every CEDR style is a single natural fiber or natural-fiber blend - GOTS organic cotton, RWS merino wool, mulberry silk, or European flax linen - with a waistband whose stretch comes from certified natural rubber knitted into cotton, not elastane. There's no polyester or spandex in the fabric or the band, which is what makes it the community pick when the requirement is zero synthetics beyond just cotton. Natural rubber is a latex, the one caveat.

A range of underwear built around a single natural fiber per style - organic cotton, merino wool, mulberry silk, or cotton/linen - with a knit waistband rather than a stiff elastic band. The merino styles give the odor-resistant, multi-day-wear performance people buy "performance" underwear for. Undyed organic cotton is offered.
