Intraknit Precision, Knee-Level Support — Smartwool at a Sample Price

The Smartwool Intraknit Active Knee Sleeve brings the same zone-specific knit engineering found in Smartwool's premium apparel to targeted knee support. Intraknit construction places compression, stretch, and warmth exactly where your knee needs them — delivering a fit and feel that standard sleeves simply can't match. Whether you’re skiing, hiking, running, or recovering, this sleeve keeps your knee warm, supported, and moving freely. This Grey colorway is a brand sample — never sold at retail — arriving in new condition with original tags.
