A note from our founder

You didn't wait for the reviews. You didn't wait for the press. You found QUOR before anyone else did, and you believed in what we were building before you ever held it in your hands. That means something to us. Every brand has a beginning, and the people who show up at the start are the ones we will always remember. This is the first production run. Limited quantity. Ships June 20th. Thank you for being here. We won't forget it.

Andrew, Co-Founder & CEO, Los Angeles

1 Performance Boxer in your selected size and colorway

Tip: pair with the Vault and a 2-pack of CryoInserts for the full sauna-ready setup.

Any man that is looking for the healthiest, highest quality boxer money can buy.

Daily wear with the structure to hold a CryoInsert when you need it
Sauna sessions, contrast therapy, and recovery work
Travel — folds flat, dries fast, and cleans up easily
Anyone who has paid attention to what synthetic fabrics do at high temperatures

Body
95% Tencel Lyocell · 5% elastane. Plant-based fiber from sustainably managed forests, produced through a closed-loop solvent process. Engineered for breathability, recovery, and softness that improves with wash.

Inner Pouch
100% Tencel Lyocell. The most sensitive contact point gets the cleanest material in the garment.

Certifications
OEKO-TEX Standard 100 certified. Independently tested against more than 1,000 regulated and harmful substances at every stage of production.

CryoInsert Pocket
Integrated into the boxer for use with the BPA-free CryoInsert (sold separately).

The Performance Boxer is designed around peer-reviewed research on heat exposure, scrotal thermoregulation, and synthetic-textile contact at elevated temperatures.
