Organic Signatures Men's Boxers 100% Organic Cotton, Soft Boxers for Men, 3-Pack (Size Large, Black)

Why we love it

Softer, cooler, organic cotton.
Moisture-wicking and odor-resistant.
Durable and ethically-sourced materials.

Main Highlights

These men’s boxers are not only softer, cooler, and more breathable than non-organic cotton boxers, they are made with more durable, longer-lasting fibers. Unlike traditional cotton underwear, these naturally moisture-wicking (no PFA's), odor-resistant boxers are naturally hypoallergenic, safer for sensitive skin, and have not been sprayed with pesticides, chemicals or fertilizers.
Move freely with the perfect amount of snug, stretch and support, soft-stretch waistband, and smooth seams. Don’t spend another minute in those itchy, scratchy boxers made with latex and chemicals that slide down and ride up. Switch to these safer, softer, roomier all organic 100% cotton boxers 3-pack if you want better-fitting tag-free underwear with a functional classic button fly and spot-on sizing for premium comfort.
Because these men’s boxer shorts are made with natural organically-grown cotton fibers that are longer and stronger, they won’t lose their shape wear after wear, or wash after wash. Unlike other cotton boxers that are weaker and broken down from chemicals, these pure cotton mens boxer underwear are high quality and made to last to keep you feeling fresh, dry, comfortable and confident.
Our fabrics are always formaldehyde-free, ammonia-free, phthalate-free, pesticide-free, latex-free, and safe for sensitive skin. The cotton used to make our men’s boxers is clean, sustainable, and ethically-sourced because it’s rain-fed, requires up to 11X less water to manufacture, produces 46% less CO2e, and uses earth-friendly methods that have the lowest impact on the environment to give you healthy, high quality, hypoallergenic underwear.
We try to be transparent in everything we do—from how we make our 100% Certified Organic Men’s Boxers, Tank Tops, Tees, and Henleys, to the Children’s Charities we support with 10% of every purchase. Currently 10% of every Organic Signatures order goes to The Neshama Foundation, a non-profit organization that funds educational, developmental, and recreational programs, and provides resources and guidance for disadvantaged and at-risk youth.

PRIMALS 100% Organic Cotton Boxers - Improves Testosterone & Fertility - Soft & Breathable - Midnight Black (3 Pack) (US, Alpha, Large, Regular, Regular, Midnight Black)

Why we love it

Boosts testosterone naturally.
100% organic and pesticide-free.
Ultra-comfortable and breathable material.

Main Highlights

TESTOSTERONE BOOSTING: The fact is toxic, modern polyester blend underwears have been scientfically proven to harm men's physical, reproductive and hormone health - and the only true solution is PRIMALS 100% organic cotton boxers. Once you make the switch, prepare to experience increased testosterone, improved fertility and boosted masculinity.
100% ORGANIC COTTON: Made with only the finest 100% GOTS certified organic cotton. Unlike other leading "cotton boxer" brands that mix in polyester and elastane, PRIMALS only uses the purest materials to craft these boxers. Plus, since its organic, it's never sprayed with pesticides unlike most other mens boxers.
NEVER SUPERWASHED: Most "organic cotton" boxer brands put their fabric through a superwash process that coats fibers in synthetic polymers and chemicals - taking away the natural benefits you're paying a premium for. PRIMALS skips the superwash entirely, preserving the pure, raw feel of real organic cotton the way it was meant to be worn.
100% NON TOXIC DYES: While other underwear brands use azo dyes to color their underwear which is proven to be endocrine disrupting, skin irritating and even carcinogenic - PRIMALS only uses 100% non toxic dye to give our boxers that sleek all black look.
BETTER FOR THE PLANET: Every 3-pack of PRIMALS 100% Organic Cotton Boxers you purchase saves 40 gallons of water and offsets 15 pounds of carbon emissions since cotton is a renewable, natural resource unlike polyester. Not to mention our underwear packaging is 100% biodegradable.
NEXT LEVEL COMFORT: When it comes to comfort, PRIMALS Organic Cotton Boxers are unmatched. Thanks to the natural properties of cotton, our boxers are soft, breathable and moisture wicking, while keeping your package cool and comfortable. We recommend sizing up a size for that elite, comfortable & spacious feel. SIZE CHART (by waist size in inches): S 29-31, M 32-34, L 35-38, XL 39-43, and XXL 44-48

Main Highlights

SIZE UP FOR A PERFECT FIT: Our organic cotton is not finished with synthetic, shrink-resistant chemicals. For the best fit, we recommend buying one size larger than you typically do. See our sizing chart for details.
DITCH THE TOXINS: Did you know? Conventional underwear is often made with toxic synthetic fabrics like polyester or inorganic cotton that are treated with chemicals and pesticides–almost like putting your boys into a bath of toxins every day. NADS underwear is made without health-damaging, endocrine-disrupting chemicals and substances. We’ve done the research. We care about your nads. You should, too.
PESTICIDES VS. YOUR PRECIOUS PARTS: Pesticides and toxins that can be found in most conventional underwear have been linked to erectile dysfunction, infertility, cancer, skin issues, and more. Polyester underwear traps heat, can mess with your hormones, and might even shrink your boys. If you’re already making the switch to healthier choices, don’t forget about the fabric that covers your most prized possessions.
UNDERWEAR FOR HEALTH & COMFORT: NADS organic cotton briefs are made with 95% GOTS certified organic cotton with 5% BPA-free elastane to enable a form fitting garment, and a 100% certified organic cotton crotch liner. We feature a no-roll waistband and performance-quality design that’s not only healthier for your boys, but nice and soft against your skin. From sofa to sauna, we’ve got you feeling comfortable and protected all day.
ORGANIC COTTON TO PROTECT YOUR PACKAGE: At NADS, we don’t just say our cotton is organic: We prove it. Our certifications guarantee that every step from farm to fabric meets strict organic and ethical standards. When we say sustainable, we mean it in every way: for the environment, for the supply chain, and for your present and future health.
BECAUSE YOUR BOYS DESERVE BETTER: You’ve cleaned up your diet. Switched to glass. Cut seed oils. But you’re still wearing toxic plastic on your most important parts? If you care about your boys, your health, and your comfort, this non-toxic underwear is worth every penny.
SIZING AND CARE: We like our parts nice and protected, and our underwear reflects that. If you’re between sizes, we suggest sizing up–check our custom sizing chart for specific fit information. As far as care goes? Cold wash and tumble dry low. Can’t get any easier than that.
