Best Plastic-Free Men's Underwear
Last reviewed August 2026
Boxers, briefs, boxer-briefs, and undershirts made from natural fibers instead of polyester, nylon, and elastane.
The short answer
Unusually for this site, the fully plastic-free options here are also the ones most people should buy. Kent's briefs are 100% GOTS organic cotton including the waistband - no elastane anywhere, compostable at end of life - and the trade is a softer, less snappy band. MARO reaches the same rating with a natural-rubber-and-cotton waistband that holds better, but natural rubber is a latex. If latex is the problem, Cottonique goes further still and drops elastic entirely for a cotton drawstring. CEDR is the pick if you want merino, silk, or linen rather than cotton. Pact is the widely available compromise at 5% elastane - not plastic-free, just cleaner than most.
Why plastic matters in men's undergarments
Most men's underwear sold today is a polyester or nylon knit with a slug of elastane for stretch - and the entire "performance" category (moisture-wicking boxer-briefs) is essentially all plastic by design. Worn all day against warm, sweaty skin, these synthetics shed microplastics and can carry anti-odor and moisture-wicking finishes right where you least want them. The plastic-free route is organic cotton, merino wool, or a natural blend, with attention to the waistband - the one part most likely to still contain elastane even on an otherwise "100% cotton" pair.
What to look for in men's undergarments
- Skip "performance"/moisture-wicking boxer-briefs - they're synthetic by definition
- Organic cotton and merino wool are the natural-fiber mainstays for men's underwear
- Check the waistband fiber separately - the band is usually where the elastane hides
- A little elastane (2-5%) gives stretch but isn't plastic-free; some brands offer natural-rubber or 100%-cotton-band options
- Merino resists odor naturally, so it's a natural-fiber alternative to synthetic "anti-odor" pairs
- Undyed/unbleached is increasingly preferred over merely organic - the fewest processing inputs against the skin
- TENCEL/lyocell is a wood-based, petroleum-free cellulose fiber that most treat as plastic-free, though a vocal minority still counts any regenerated fiber as synthetic
Recommended men's undergarments
Every product here we'd actually suggest — best-in-class picks first, then the rest by how plastic-free they are.
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.
100% Plastic-Free Organic Cotton Boxers
100% GOTS organic cotton body with a natural-rubber-and-cotton waistband instead of elastane - the men's answer to a genuinely plastic-free waistband. Natural rubber is a latex.
Latex-Free Drawstring Boxer Shorts
100% organic cotton down to the drawstring, thread, and label - no elastic at all. Built for latex/spandex-sensitive skin; the purest plastic-free option here.
Organic Cotton Brief
100% GOTS organic cotton including the waistband - no polyester, nylon, or elastane anywhere. The rare genuinely plastic-free pair, and compostable at end of life.
Everyday Boxer Brief
95% GOTS organic cotton / 5% elastane, widely available and affordable. The accessible organic-cotton pick - minimal-contact, not plastic-free.
Hemp Boxer Briefs
53% hemp / 44% organic cotton with 3% spandex - a naturally odor-resistant, mostly-natural boxer brief. Not fully plastic-free because of the elastane woven throughout.
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.

Men's undergarments to avoid
Popular options that look plastic-free but aren't — and whole categories worth skipping.
Hanes ComfortSoft Cotton Brief (Tagless Multipack)
Often a '100% cotton' body, but the ComfortSoft covered waistband is a polyester/elastane band riding against the skin.
NADS
GOTS-certified organic cotton and marketed hard on being non-toxic, which is real - but it doesn't clear the bar for a pick. The everyday styles carry 5% elastane, and the plastic-free community has repeatedly flagged durability (reports of pairs ripping within a year) and called the eco-forward positioning greenwashing given the synthetic band. A fine organic option; just not one we'll rank over the natural-rubber-band picks.
Boody Everyday Boxer Briefs
Soft and popular, but built from bamboo viscose (95%) with 5% elastane - and bamboo viscose is a semi-synthetic regenerated fiber made with harsh chemistry, not a natural fiber in the cotton/hemp/wool sense. Between the processed viscose and the elastane band, it doesn't belong with the natural-fiber picks; the Seamfree style adds nylon on top.
Saxx (Vibe, Daytripper, Quest, etc.)
Comfortable and well-designed, but effectively all plastic: the lines run 95% viscose/5% spandex, 97% polyester/3% elastane, or 77% nylon blends depending on the style. This is the synthetic "performance" underwear the plastic-free picks are meant to replace.
ExOfficio Give-N-Go (and similar "moisture-wicking" boxer briefs)
The classic travel/quick-dry boxer brief - and a textbook all-synthetic construction, commonly around 94% nylon / 6% spandex. Marketed on quick-dry performance, which is exactly the polyester/nylon story; not plastic-free in any sense.
