Our featherweight work pant just got warmer. The Costello Lined Tech Pant pairs a lightweight polyester brushed tricot lining with a breathable 5 oz fabric, so you stay comfortable working in cooler weather without the extra weight. 4-way stretch and articulated knees deliver full range of motion - whether you're climbing, crouching, or kneeling - while durable mini ripstop nylon prevents snags and tears. A Durable Water Repellent (DWR) finish sheds water and stains, and a multi-pocket system keeps your gear organized and within reach.
