The Detour 8301 is made of durable top grain buffalo leather and features polished silver colored hardware with leather pull tabs for easy use with gloves. It’s available in sizes small thru three X and fits very accurate per the size chart on the listing. So, if you’d like a little extra room for layering, be sure to go one size larger. Jessica is 5’8’ 145 and fits wonderfully in the medium. The main closure features an all metal YKK zipper and the neckline has a single snap euro style collar. Adjustability equals comfort. So, the waist features snap and zipper combination gussets for adjustability, as do the cuffs of the sleeves for easy on and off. The front of the 8301 features two zippered vents and two hand warmer pockets for breathability and storage. The back of the jacket has some nice detail with two zippered vents for extracting warm air and a multiple panel construction. If you open the jacket up you can see the removable full sleeve thermal liner that is flanked on each side by a zippered pocket. On warmer days, you can remove this liner by unzipping it from the shell and unsnapping it from the cuffs of the sleeves.
