Shak:

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.

How Do I Determine My Size?

We recommend a general body measurement guide to determine your size in Ibex clothing. This sizing chart is not garment specific, but in fact a body measurement chart. Here are some helpful hints when measuring:

Bust/Chest: relax arms at sides, keeping the tape parallel to the floor, measure the fullest part of your bust/chest
Waist: keeping the measuring tape comfortably loose, measure around your natural waistline
Hips: standing with heels together, keep the tape straight and parallel to the floor, measure around the fullest part of hips
Sleeve Length: a 3-point measurement, standing with arms relaxed and slightly bent at sides, measure from the base of the neck to the shoulder and then from the shoulder to the wrist bone, add together measurements
Form-fit: garment designed to fit snug to the body throughout
Semi-fit: garment will be contoured to the body
Regular-fit: garment will not be slim, but also not oversized
Relaxed-fit: garment drapes loosely on body

Still need help determining your size? Call 800.773.9647 or email us at info@ibex.com for specific garment measurements.

This is simply a really good looking piece of clothing. I can wear as a top or as a layer underneath. It is relatively close fitting so you wouldn't want to wear anything bulky or loose fitting underneath.
Paul R on Aug 20, 2016
I bought this for my partner for day-to-day use and cycling. It's a nice lightweight top that's holding up well to frequent use.

Classic! Easy layering allows use in wide range of temperatures. I always have my Shak Jersey within reach.

Chris J on May 25, 2016
I'm very fond of my Shak Lite 1/2 Zip and wanted a similar sweater in a heavier weight.
Charlie on May 4, 2016
we buy several every year, almost a base layer for our cold Colorado winters. heavy enough wool to keep my husband warm whether indoors or outdoors.
dog lover on May 3, 2016
Because of the quality, and finally something in red!
Can you make the Arlberg Jacket in RED? I would buy it immediately!

By the way did you inquire about being a supporter of the NSP? National Ski Patrol? Other patrollers saw my ibex stuff and asked about it and were not aware of it!!!
Marc G on Apr 27, 2016
I like the density of the fabric, the classic, clean lines, and the color.
Sensei the cycl on Apr 7, 2016
I recently purchased an IBEX Hooded Indie. I have liked it so much I decided to experiment with other layering systems for the cold and wet trails or for my Search and Rescue missions. This layer is a little thicker than my Hooded Indie. We shall see if it performs as expected on cold days on the trails or as a mid layer on snow and ice trainings with my search and rescue team.
John B on Mar 28, 2016
Like quarter zip front and weight of shirt. Perfect for layering
Charlotte J on Mar 20, 2016
I love and live in this shirt. In summer, it's my outer layer, in winter it's my inner layer. Warm, durable, good-looking.
Ben K on Mar 9, 2016
High quality, long wear and great fit, would highly recommend.
Richard P on Mar 8, 2016
Replace aging zip-neck sweaters for business casual wear, plus cold-weather sports mid-layer. Have had my eye on Ibext for a while, tried a demo at the Mount Washington Ice Fest and it was great, so taking advantage of this sale to to buy my first two articles. Thanks!

i have owned this model before
Tracy B on Feb 3, 2016
Wanted wool. Saw your item for sale in a retail store in Victoria Canada, but they didn't have it in black. Well made, overall, but I'll take this opportunity to tell you the stitching around the wrists (sleeves) is fraying. Still like the product (wool,obviously) but perhaps the stitching could be improved? Thanks
Robert S on Feb 3, 2016
You do not have a womens half zip in this shak weight fabric. So I am trying a mens small

similar to previous purchase as part of layer system

Guest S on Jan 18, 2016
Bought one several years ago and its warm, durable and retains no odor. Regular washer dryer cycles and still holding up over years of use. Now I have black and red to go along with the blue. Great product.

Will wear it skiing
marilyn m on Dec 4, 2015
Great reviews!
Maritza R on Dec 1, 2015
It will always be a favorite and always in the Ibex medal round. PLEASE RELOCATE IBEX LOGO. It is annoying and I talk up Ibex so much AND it is no longer necessary for continued booming success. I like the location on the T-shirt's sleeve much much better. Friends and family have the same "complaint."
Kevin E on Nov 30, 2015
This looks like a great option to wear by itself, as well as under another article of clothing. I like the versatility!
Guest S on Nov 30, 2015
The "go to" top.
Mark G on Nov 25, 2015
I have been wearing shaks for years. I have several. it is the one piece of clothing that works well in the office and out climbing all from the same perfect weight shirt.
Dallen W on Nov 18, 2015
My husband loves your stuff! We visited your store in Seattle and he tried it on and loved it. I got it for him for a Christmas present. We love Merino wool and love that you are an American company making great quality clothes.
Guest S on Nov 8, 2015
I bought one for my son about 8 years ago (it's still in perfect condition, btw) and he requested another one for Christmas this year.

He loved it
Weekend wear. Could also cycle in it. Love the longer length.
November 13, 2010
incredible jersey
I love this jersey. It's one of those magic garments. It fits beautifully, athletic but flattering fit. I'm 5'11" and weigh 150 lbs. and long limbed, the medium fits me perfectly. I commute by bike and wish I could wear this every day. It has a broad comfort / temperature range and can be layered to suit very cold temps. I'm a huge fan of wool and this is the best, most versatile single wool garme

My favorite all-purpose piece...
It's the one piece that I take everywhere...dresses up nice with a pair of khakis. Mine has been snowshoeing with me and the next day at the office. Just get one.

5x a week
I own three black Shaks. I wear them probably 5x a week. To work, out for dinner, working in the yard, playing golf in spring and fall, biking, everywhere. I travel a bunch and this thing is great in lieu of a blazer. Wad it up, stuff it in your backpack, it still looks great. I'm thinking I need some new colors, then I can wear it 7x a week.

This is my 2nd one.
The first one is still going strong after three years of daily wear.

Very Nice Jersey
This is a good all around jersey just like it is supposed to do. I like the blue a lot and the sales price is great. I ordered a small and this is perfect for me - 5'10" 155 lbs to have a contour fit If I ordered a Medium it would be too baggy. 38" chest.
October 25, 2010
Still a great top, but very short
I ordered this year's Shak for my husband. He's 6'0" 150 lbs, and wears size M. It's the same good quality Shak as previous years. The raglan sleeves are great, they allow unimpeded range of motion. But, compared to previous years, the fit is boxy and the torso length is too short in front. For what it's worth, even I used to wear mens' Shaks (size S), back when they were cut longer and slimmer.

Nice Quality Jersey
This was my first IBEX jersey and I'm very happy with the Shak. I am between a S and M and since I don't like garments that are baggy I took the S (also to get the great Outlet price) The Small is a good fit except I'm 5'11" have long arms and would like another inch in the arms and even two more inches in the torso. But all and all I like this jersey a lot and love the Blue! Hopefully it will wea

Incredible Product!
I bought this for my husband for his birthday and he hasn't taken it off since he opened it! He absolutely loves it!

Gift made mother-in-law look smart.
My son-in-law has several Ibex products, so I was sure he would like the sweater and he did.
