Unbound Merino Merino Boxer Briefs
Merino-dominant boxer briefs for odor resistance and travel, blended with nylon and elastane. Natural-fiber-forward but meaningfully synthetic - minimal-contact.
The verdict: Minimal plastic contact
Merino wool is the main fiber and does the real work here - it's naturally odor-resistant, so this is a natural-fiber alternative to synthetic moisture-wicking underwear. But the blend carries a meaningful share of nylon and elastane for durability and stretch (commonly around 84% merino / 12% nylon / 4% elastane, though the exact mix varies by batch and color, and some variants add TENCEL). That ~16% synthetic content makes it minimal-contact, not plastic-free.
What it's made of

| body knit & band (elastane) ~4% elastane for stretch - plastic | Elastane Spandex / Lycra | Yes primary |
A merino boxer brief built for travel: because merino naturally resists odor, they can be worn for days between washes, which is the whole appeal. Temperature-regulating and comfortable. Buy it for the merino performance.
