New size, fit and fabric information in the size chart tab

If you're looking for a baselayer to stand up to the coldest winter days Mother Nature throws your way - and we've had customers wear Comet on expeditions in Antarctica and Alaska - then you've come to the right place. Duckworth's proprietary Comet fabric is natural-technical mash-up, combining a Montana-grown Merino Wool outer layer and a recycled polyester inner layer. Why the combo? Polyester is hydrophobic, meaning it will wick sweat and moisture right off your skin and into the hydrophilic wool layer; wool atomically becomes even warmer when introduced to water and water vapor, thus explaining why the slim-fitted Comet Leggings will have your legs feeling dry and toasty even in the nastiest conditions. Soft to the touch, durable, anti-odor, moisture-wicking, quick-drying, and versatile: your one-stop-shop baselayer legging.

Why Duckworth Comet Fabric?

Composition: 94% Montana Merino Wool and 6% nylon outer layer, 100% recycled polyester inner layer

Weight: 315 gsm

NEW SIZING, FIT & FABRIC INFORMATION: You spoke and we listened - following ample customer feedback, we've increased the inseams on these top-performing Merino Wool long johns. Additionally, we've slightly increased the grade of our X-Large and XX-Large fits for a better match to our size chart. You will notice more room in these fits compared to previous years' models. We've slightly adjusted the outer-layer material to include 6% nylon for the purpose of adding extra strength to the wool yarn, following feedback from our ranching team the outer layer would occasionally develop holes after rigorous use. The fabric also features a 315 GSM construction vs 275 GSM in year's past, for optimal warmth and weight in the colds of the American backcountry.
