The Original 3D Pouch, Reimagined in Luxury Modal
The BN3TH Classic Icon Boxer Brief SD is the brief that put three-dimensional support on the map. Built from 95% TENCEL™ Modal and 5% spandex, it delivers a cloud-like feel that stays smooth against skin all day, whether you are in the water, on the trail, or at a desk. TENCEL™ Modal is sustainably sourced, making this the rare brief that earns its premium price tag on both performance and principle.
BN3TH MyPakage 3D Pouch Technology
The defining feature of the Classic Icon is BN3TH's original 3D contour pouch. Rather than laying flat like a conventional brief, the pouch is shaped to provide natural lift and separation, eliminating the bunching and friction that standard underwear creates during movement. The fit is supportive without being constrictive -- exactly what active days demand.
Construction That Earns All-Day Confidence
- Chafe-free flatlock stitching: seams lie flat against skin so there is no rubbing, even during extended wear or high-output activity.
- Premium no-roll waistband: the branded elastic band stays put through every movement without folding, digging, or creeping.
- Cloud-like breathability: TENCEL™ Modal's open fiber structure allows airflow to move through the fabric, keeping temperature regulated naturally.
- Ultra-soft, smooth feel: the 95/5 Modal-spandex blend is notably silkier than cotton and retains that feel wash after wash, guaranteed to stay smooth.
Fabric and Sustainability
TENCEL™ Modal is produced from sustainably harvested beechwood using a closed-loop process that recaptures the solvents used in fiber production. The result is a fabric that is measurably softer than conventional cotton, inherently moisture-wicking, and significantly more environmentally responsible. The 5% spandex addition gives the brief the two-way stretch needed to move with the body without losing shape over time.
Care
Machine wash cold, tumble dry low. Avoid fabric softeners -- they coat Modal fibers and reduce the natural softness over time. Do not bleach or iron the waistband.

Frequently Asked Questions
- What is the BN3TH 3D pouch and why does it matter?
- The 3D pouch is BN3TH's original contoured support system. Instead of the flat panels found in standard briefs, the pouch is shaped three-dimensionally to provide natural lift and separation. This eliminates friction and bunching during movement, making it significantly more comfortable for all-day and active wear.
- What is TENCEL Modal and how is it different from cotton?
- TENCEL™ Modal is a plant-based fiber produced from sustainably harvested beechwood. It is notably softer and smoother than cotton, more breathable, and has better moisture-wicking properties. It also holds its softness through repeated washing where cotton can stiffen over time.
- Is the BN3TH Classic Icon Boxer Brief good for working out or surfing?
- Yes. The flatlock stitching eliminates chafe during high-movement activity, the no-roll waistband stays in place, and the Modal-spandex blend moves with the body and manages moisture. It performs well across everyday wear and active use.
- How should I care for the BN3TH Classic Icon Boxer Brief to keep it soft?
- Machine wash cold and tumble dry low. Avoid fabric softeners as they coat Modal fibers and reduce their natural softness. Do not bleach or iron the waistband. These steps preserve the TENCEL™ Modal feel wash after wash.

- Is the BN3TH Classic Icon Boxer Brief sustainably made?
