Size Recommender
Sherpa jackets make for an ideal winter layer, designed to provide warmth and comfort. Sherpa material is thick and has soft, fuzzy looping, which helps to trap heat near the wearer’s body. The Mammoth Sherpa Jacket also features a windproof inner polyester lining, making it a barrier for cold, wet weather.
Sherpa material also offers superior breathability, allowing moisture to escape and keeping you warm and dry, while also regulating internal temperature. The Mammoth Sherpa Jacket was also designed to be lightweight enough to be layered with other pieces of clothing, making it the perfect piece no matter the season.

"Great jacket. Sizing is a little strange but not horrible. Very baggy with a short length. Very warm jacket for colder weather. Bought this before the hooded version came out. Kinda wish i waited for that. Still, it's a nice warm cozy jacket."
"As it is with every Iron & Resin piece, it’s just so thoughtfully constructed. The materials, the bottom hem design, three inner pockets, a spare button bag built into the jacket! Quality is unreal for the price. It’s a handsome and highly functional piece."
"I absolutely love this jacket. It's super warm relative to how light it is and fits great (5'10", 185). The three inside pockets are great."
"True to size loads of internal pockets. Super warm, quality zips. Overall another fantastic garment from I&R."
"I seriously want to wear it everyday. It’s warm and comfortable and very well made"
"TOP!"
"Warm and good sized practical pockets."
"Warm, has lots of pockets, feels like great material and very stylish. Fits great everywhere but does look short on the body, at 6'2 200 lbs. The elastic lining that pulls the bottom in can exaggerate your rear so if you aint hitting leg day this probably aint for you."
"Awesome sherpa jacket, great color. I like the zippers on all the pockets. I'm 6'1' 178 and size Large fits great."
"This is gonna be warm as hell this winter."
