Boxer Trunk

Why SDEPP? Most underwear is an afterthought. Grabbed in a multipack, worn until it falls apart, replaced without a second thought. We think that's worth changing. SDEPP was built on a simple belief: the most intimate piece of clothing you wear deserves the same consideration you give everything else. No pinching. No scratching. No compromises — and no cost to the planet. The most comfortable underwear you've ever worn. Our boxer briefs are made from Tencel™ Modal fibre — a naturally derived material from sustainably managed Austrian beech forests. The result is a fabric that's 5× softer than cotton, temperature-regulating, and incredibly kind to sensitive skin. Paired with ROICA™ bio-based elastane for a precise 4-way stretch that moves with you, not against you. Made better, from the start. The beechwood used to make Tencel™ Modal grows without irrigation or pesticides. The production process is closed-loop — meaning 90% of water and solvents are recovered and reused. Compared to conventional cotton, the environmental impact is reduced by multiples: less water, less CO₂, less waste. The underwear feels better. And it leaves the world better too. That's not a trade-off. That's just SDEPP. Sold on SDEPP (https://sdepp.com/products/boxer-trunk).
