The Tectonic is very simply warmer than your average softshell. Rich, buttery-soft fabric is reinforced on the interior with Omni-Heat thermal reflective, which boosts heat retention by an average of 20 percent. Omni-Shield advanced repellency keeps out rain and stains. Super-stretching, highly breathable panels run from side to underarm area, making this piece great for high-octane activities. Adjustable cuffs and waist provide supreme customization. Zip-closed pockets and an internal key clip keep valuables secure while comfort cuffs with thumbholes ensure your sleeves stay locked in place.
