"What Our Gearhead® Experts Are Saying:""The Tista Sweater Pullover Hoodie has earned a permanent spot in my ski bag because the activated charcoal fiber construction keeps it fresh through back-to-back sessions without any extra effort on my part. It packs down small enough that I throw it in without thinking, and the tall collar handles the cold starts on Nordic mornings better than almost anything else I own.""The Swix Tista Sweater Pullover Hoodie is built from technical fibers made from activated charcoal derived from coconut husks, a construction that brings natural odor resistance, moisture wicking, and UV protection to a slim, packable mid-layer that works across every cold-weather discipline in your rotation. The touch of stretch moves freely through every stride on the Nordic trail or step on the skintrack, and the tall collar keeps cold breezes off your neck when the effort drops and the temperature settles back in."
