The QUOR Sauna Boxer is a dual-layer boxer short engineered specifically for heat exposure. The body is made from a 95% bamboo / 5% elastane blend for breathability and comfort, while the groin area features 100% organic cotton for targeted protection. Each boxer includes an integrated pocket designed to hold our custom cooling insert, keeping your core temperature regulated where it matters most.

We chose this hybrid approach for a reason. Bamboo offers superior thermoregulation, natural antimicrobial properties, and a soft hand feel that performs beautifully in high-heat environments. The 100% cotton groin panel provides a gentle, chemical-free barrier right where temperature sensitivity is highest. It's function-first material selection, not marketing—every fabric choice serves a specific purpose.

The cooling insert is a slim, flexible pack that slides into the integrated pocket in the groin area of your boxer. It absorbs and disperses excess heat during sauna sessions, keeping scrotal temperature lower than your overall body temperature. Simply store it at room temperature or cool it briefly before your session, then slip it in and go.

You'll notice a comfortable, subtle cooling effect—not an ice-cold shock. The insert is designed to work with your body, not against it. Most men report that after the first minute, it simply feels like a natural, comfortable temperature difference. You won't be distracted from the meditative benefits of your sauna session.

Yes. We use OEKO-TEX and GOTS certified materials, which means our fabrics have been independently tested and verified to be free from harmful substances. We believe premium products should also be clean products—no shortcuts.

The research is clear: sustained testicular heat exposure can temporarily reduce sperm quality, count, and motility. Sperm production (spermatogenesis) is optimally performed at 2–4°F below core body temperature, which is why the body naturally positions the testes externally. Saunas, hot tubs, and other heat therapies can elevate scrotal temperature well above this optimal range.

Reproductive health is a long game. Sperm take roughly 74 days to fully develop, and cumulative heat exposure can impact that cycle. Protecting your baseline now means better outcomes when the time comes—whether that's next year or five years from now. Think of it as future-proofing your health.

In addition, our boxers are made for daily wear and use regardless of if you sauna, or plan to. We wear them every day!

No. QUOR is a wellness product designed to support your thermal therapy routine, not a medical device. If you have specific fertility concerns, we always recommend consulting with a urologist or reproductive endocrinologist. Our products complement—not replace—professional medical guidance.

The boxer should feel snug but not restrictive—similar to performance athletic underwear. You want the cooling insert pocket to sit securely in the right position without shifting during movement. If you're between sizes, we recommend sizing up for a more relaxed fit.

Machine wash cold with like colors. Tumble dry low or hang dry for maximum longevity. Avoid bleach and fabric softeners, which can break down the bamboo fibers and reduce the fabric's natural antimicrobial properties over time. The cooling insert should be wiped clean with a damp cloth—do not machine wash or submerge it.

With proper care, our boxers are built to last 12–18 months of regular use. The bamboo blend is naturally durable and maintains its softness wash after wash. If you rotate between multiple pairs (which we recommend), you'll extend the life of each one significantly.

Absolutely. A single QUOR Sauna Boxer is $48 and includes one cooling insert. We're confident you'll be back for more, but we understand wanting to experience the product firsthand before committing to the full system.

We currently ship throughout the United States and Internationally.

It's pronounced "core"—as in your core health, your core strength, the core of who you are. We chose the name because everything we build starts from the inside out.

QUOR was born from a real problem. Our founder experienced the incredible recovery and mental clarity benefits of daily sauna use, but when he and his wife began planning for a family, he faced a frustrating trade-off: give up the practice that was transforming his health, or risk his reproductive future. That shouldn't be a choice any man has to make. QUOR exists so you don't have to choose.

Our boxers are manufactured by a premium textile partner in Turkey, known globally for producing some of the finest fabrics and garments in the world. Every piece is crafted with the same attention to quality you'd expect from high-end apparel.
