Reviews

Softer and a bit more casual than the Shak

"I bought this in black and was wearing daily so I purchased the blue color as well. I debated between this and the Shak Hoodo Hoodie. It has a slightly more buttery feel than the Shak, and warmer in the wind. However, it does look a little sportier and less formal. I only have to dress Montana business casual for work so I wear this both in the office and on the trail."

— Erica L. (5/5)

Mammoth Hoodie

"I thought the Shak jacket was the best ever. But now I can't take off the Mamoth Hoodie. Definitely, for sure, buy 1-2 sizes bigger. I'm a Large in Ibex and the XL is perfect for the Mammoth. I'm 5'6", 160 lbs. This is my favorite piece of clothing."

— Rebecca L. (5/5)

comfortable, yet stylish and a perfect fit

"I love this hoodie, which is well constructed as fits well and the color is great!"

— Bo H. (5/5)

Fantastic hoodie but already has a hole in the pocket

"The warmth and coziness is wonderful. I really love this jacket and wear it all the time. Unfortunately, one of the pockets developed a hole before I had even washed the hoodie once."

— Shalini S. (5/5)

Fabulous ski gear; disappointed about color

"This jacket keeps you warm while moving without the sweat! Comfortable all day. I ordered one that looked white/gray but is really a bit of a sweatshirt gray and not flattering. So the sweater is great but the color is not so great. I was headed out on a trip so not time to exchange the color. My bad!"

— Fritz B. (5/5)

Way too small

"Really disappointing that they are made too small."

— Kimberley d. (1/5)

Love it!

"Well made, softer than I imagined, true fit. Love the two-way zipper. Had to get one for her too."

— Kevin B. (5/5)

Great jacket

"Love this jacket! Warm and durable, great over my base layer skiing backcountry."

— Valerie M. (5/5)

Runs too small

"Elbows are too tight and so is waistband in a size large"

— Jessica C. (1/5)

Mammoth warmth

"❤️❤️❤️ this product. More purchases to come!"

— Pamela L. (5/5)
