The Kirkland Signature Men's Tencel Boxer Brief comes in a 4-pack and is crafted from TENCEL lyocell, a sustainably sourced fiber derived from wood pulp that is renowned for its exceptional softness, breathability, and natural moisture management. The fabric feels smooth against the skin and is notably cooler than cotton, making it a comfortable choice for everyday wear.

Each boxer brief is designed with a contoured, supportive fit that moves naturally with the body. The no-fly design offers a clean, streamlined silhouette, and flatlock seams help minimize friction and chafing. The waistband features the Kirkland Signature branding and is engineered to lay flat and hold its shape through repeated washing.

TENCEL lyocell is produced through a closed-loop process that recovers and reuses solvents, making it one of the more environmentally responsible textile choices available. The 4-pack provides excellent value for a premium fabric at Costco pricing.
