This item is online only, one-of-one, and GONE when it's gone.

Intraknit construction zones ventilation and support into a single seamless base layer, offered here as a brand-new Smartwool sample never sold at retail.

The Smartwool Men's Intraknit Boxer Brief uses a slim fit built from a Merino-TENCEL blend that manages moisture, regulates temperature, and resists odor. Intraknit technology integrates insulation, articulation, and ventilation directly into the knit, and minimal seams are designed to reduce chafing during movement. This pair comes in Nightfall Blue, a deep blue heather tone. As a brand sample, it arrives new with its original tags still attached, sourced directly from Smartwool rather than through retail.

Size: M
Color: Nightfall Blue
Condition: Sample. New with original tags. Procured directly from a brand or brand sales representative in new condition. Tags may state 'sample' or 'sales sample'.
Original Retail: $55.00

Key Features:

  • Slim Fit: Follows the contours of the body for a close, unrestrictive feel.
  • Merino-TENCEL Blend: Combines moisture management, temperature regulation, and odor resistance.
  • Intraknit Technology: Integrates insulation, articulation, and ventilation into the fabric.
  • Minimal Seams: Designed to help reduce chafing during movement.
  • 4.5-Inch Inseam: Sits at a shorter length for unrestricted movement.

Ideal For: Anyone who wants a breathable, chafe-resistant base layer for training or everyday wear. As a brand sample, this pair comes new with tags directly from Smartwool, never sold at retail, which is why it's priced below its original retail value.
