The Ibex Promise
The Shak Classic is the holy grail of training partners: reliable, tough, and guaranteed not to spill the beans about that time you forgot to pack the white gas for a three day trip. Made of 100% Merino, this jacket is top-notch insulation for all your wilderness endeavors. Bonus: its modern cut will perform just as well in the boardroom as it does in the backcountry.

We start with the best New Zealand Merino wool to make a range of insulative yet breathable midlayers that outdoor enthusiasts swear by. This exclusive knit is square and dense, creating a rugged yet soft fabric with inherent stretch and long-wearing durability. Our Shak fabric is best used as a midlayer but is soft enough to wear as an expedition-weight baselayer and substantial enough to be used as an outerlayer in some conditions. No matter how you wear it, the performance is unbeatable. Machine washable.

My North Face merino sweater was beginning to show signs of wear and this seemed like a good replacement. Plus, I got it at a price that was fair.

Love my old shak hoody and it was time for a refresh.

I wear the vest version of this jacket everyday during the dry season at my home in DRC, and on cool mornings while traveling.

This sweater wears like iron! My husband wears it everywhere . It works in cold and cold climates. Great product!

Found this on sale and love it. Mid layer or light outer layer...does it all! Good fit and luxurious feel.

On sale and wanted to try out the Shak Classic. All of the my other Ibex purchases have lasted and been very comfortable, and I wanted to upgrade from fleece.

Coolest gift for my serious athlete young adult son.
Wendy G on May 4, 2015
I chose this for my 91 yr old father as a birthday gift. He needs something fitting to stay warm. A zip opening is important with neck coverage that can breathe. Layering is ideal for seniors. Only disadvantage is isn't machine washable - a real must.

My husband and four sons find this the most useful item of clothing they own. It can be worn under a suit jacket and look smart.

My husband is 6' and 170 lbs. Should I order him a Large or a Medium?
Roberta S on Jul 5, 2015
BEST ANSWER: Hey Roberta, I'm 6 ft and about 180(ish) lbs....while I have three shak classics in large, I regret not buying mediums instead. But depending on your husbands build, I'm sure a large would be fine. I'm an avid cyclist and don't work out as much on my upper body so I'm much skinnier in the shoulders and across the chest prior to me buying it a couple of years ago....if he likes a "slim" fit, I would go with a medium...if he likes a bit more room for layering, etc..large is the way to go....hope that helps! John
I am 5'10" and 150 lb. What size shake do you recommend?
A shopper on May 25, 2015
BEST ANSWER: I'm 5'9" and 190 lbs. I wear a 43 regular suit and I have a large Shak Classic. The arms and shoulders should fit you fine but you could probably get away with a medium too. It's soft and has a bit of stretch to it. Perfect on top of any crew neck or polo.
when are other colors than black available?
John F on May 28, 2015
BEST ANSWER: The Men's Shak Classic is our heavier weighted Shak and is more prominently offered in our fall/winter line. During the summer we only offer it in the Black but when the fall line is launched in September it will be available in four colors: Black, Pewter Heather, Red Ant and Blueprint. Thank you for your question.

two things. . .
I try to buy a couple of Shaks a year and until this batch they have been just terrific - the most brilliant things I have ever worn - but the two I have just bought flap around my middle and look just ordinary. Have you changed the dimensions? If so why?

And why no XL in the triathlon red, can I just ask? It is a beautiful colour and I'd still buy one and have it taken in if you have changed the

Love shak but it seems Ibex changed fit
I agree with Toby that past Shak jackets had a better fit. Just bought this one a few months ago and there is a flap on the sides in the middle. I usually take an Xl and it fits great - now its too big and not form fitting at all. [...]

SHAK Jackets -
I bought one of these jackets for every member of my family for CHristmas this year. We go from an XXL son in law to a S daughter in sizes - and no one was disappointed in color, fit, size of feel. I have already seen my kids wearing their jackets everywhere, and my husband, who is never easy to please and has more outdoor gear than most catalogs, is loving his Shak. All in all, one of the best

Men's full zip is a great garment
I'm very happy with the men's full zip shak classic. The fabric weight is very versatile and the fit is excellent. I have worn it in a variety of indoor and outdoor conditions and I love the combination of "just right" warmth and breathability. It works well for a casual day in the office as well as a hike with the dog. I don't normally carry my cell phone in a shirt but the chest pocket is useful for that when needed.

Want my old shak back
I have an older full zip shak that I've worn so often I've worn holes in the sleeves. It's been by far the best technical wool piece I've owned. This new shak just doesn't have the same fit. The body is now constructed out of fewer peices, making it much more boxy and less amenable to layering. I know it probably kept costs down, but I'd rather pay a bit more and keep the fit.

Great material poor fit
Great idea and good weight for shirt, but very poor fit for a shirt that was supposed to be semi fitted. I am 6'1 175lbs and the size medium shirt was to short in the sleeves and torso. The fit was ok in chest but to baggy at the waist.

Favorite Jersey
I bought one of these as a cycling/hiking outer layer. It became my favorite piece of clothing the moment I tried it on. I'm 5'11 and about 170 pounds and the medium fits well. Snug, but not too tight.

It's soft, warm, breathes, and doesn't stink. Very warm even when soaked through with sweat and rain. This should provide all-day temperature regulation down into the low 40s or below with proper l

Great all-around sweater
I use Shak almost daily in the fall and winter. It fits well and offers the right amount of warmth for Northern California. I have two Shaks, one small and one medium. I am 5'7 and 147 lbs; I use the small when using one thin layer and the medium when using more substantial baselayers.

Awsome Shak Full Zip
I love this jacket!!!! I've bought this jacket a year ago & got more use out of this for all three seasons. I mostly hand wash it & air dry it out w/o any problems. I just bought one for my sister.

A must...
I must say I find myself grabbing for this everytime I leave the house. Sometimes I wear under neath a shell and sometimes on its own. I am extremely impressed with the warmth this has. I like the look so I have worn it in formal occasions as well. I really like the benefits of Merino. IBEX makes awesome products... keep up the good work!
