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

I cannot say enough about the warmth of Merino wool.
This will be a perfect added layer when I need it.

My son has this vest; looks great and is exactly the right weight for my husband. He has another Ibex vest which he loves but this is a better weight for our up-coming travel.

Stephen C on Oct 31, 2015
Have the black version of this and I love it. I'm 6'4" and 185. The XL is needed because of the trim fit. The length is great for us tall guys.

Spencer H on Jun 2, 2015
I purchased as a gift for my husband. M was a bit tight so exchanged it for L. Fits well for doing chores (chopping wood, plowing, etc)
KD on May 29, 2015
Very good, just short of great.

The right added warmth in the Bay Area. Cut, color and quality of wool are perfect for trails, pitch meetings and first dates.

My only gripe: Why no slim zip pockets at the hips?!? While the breast pocket bulges with anything besides a few bills, and/or cards, hip pockets would have hid keys/phone and retained the svelte lines.

Previous experience with Ibex products and quality control.

Nothing beats wool for warmth.
THOMAS O on Apr 29, 2015
Sorry, I sent this one back: too small and it wasn't me! Really, just felt like a Medium for some odd reason. The ones with the sleeves were great, but this one was sized too small.
Steven A on Apr 27, 2015
Item allows for versatile layering at a wide range of temperatures. Also, it's durable, packable, and washable.

does this item run large, small or true to size?
A shopper on Aug 1, 2015
BEST ANSWER: Hello the Shak Vest is a Semi-Fit so a little snug. This item does fit true to size. Thank you.
Is the collar lined with some material that does not itch?
THOMAS O on Apr 29, 2015
BEST ANSWER: The collar does not itch at all - I did not wear this with a t-shirt though - i always seemed to have a shirt with a collar - even though these items are made of wool, the material is so fine that there is no itch or even a hint of itch - not quite but like a pair of 150's wool trousers that feel like they are made of silk....

worthwhile in-vest-ment
This vest is a nice weight, and at 6' and 185 lbs, a L fits perfectly, close to the body as a vest should but not to the point of being tight. There's enough stretch in the fabric to alleviate that, anyway. Haven't used it yet for anything other than insulation while relatively sedentary indoors, and for commuting by train, driving, and walking in the city. Great as a layer under heavier layers
January 31, 2013
a beautiful garment
I appreciate the chest pocket, perfect for cell phone. I'm 6'1" 170lbs 40" chest, 34" waist,and the medium fits perfectly over a lightweight wool medium size zip T-neck. Could be indispensible. I bought a color that is not now listed-Pewter Heather. Ibex should make this color a staple IMO.
November 27, 2014
Doesn't fit as well as I'd like it to
The material of this vest is top-notch, soft, comfortable and durable. Workmanship is great. The vest is too long in the body however and not close fitting enough especially in the lower portion, given the stretch of the material. I was hoping for a more tapered, close fitting garment. This is too loose, I feel.

Great for work, play and travel
This vest is the ideal three-season layer for under a jacket or parka. It goes with me around town on cool evenings. It's perfect for travel. My dark gray one is suitable on it's own around the office. I agree with the description that this is Ibex's most versatile piece. I love it!

The most versatile article of clothing I own?
This is a terrific garment. I'm 6'0" and 185 lbs. and got the L which fits me perfectly. It adds just the right amount of warmth and wind resistance in a wide range of temperatures, and it looks as good as it is comfortable. Bravo!

The Perfect Vest
Initially I thought the vest might be too tight but the stretchy fabric is so comfortable and the trim fit looks great. I ordered my usual size. It's perfect for a mid-layer, not bulky but warm for its light weight. A great Ibex product.
December 2, 2012
Fantastic Vest
Shak Vest is the perfect mid-layer. Warmth without any bulk. The trim, close fit is very attractive. I ordered my usual size and the fit is just right.
December 9, 2012
Great product
I have several ibex products. They are first rate. Service is the best. I wear them all the time. I wear a size 42 suit coat. Depending on fit I order medium or large.

Great Vest
This vest is awesome. I have it in the blue and have the medium and it is form fitting, I am 5'-9" 165lbs. I wear it over a light weight long sleeve shirt when I run and over a dress shirt for work when I need a little extra warmth. The vest is not thick or bulky and is a nice light weight vest that is very versatile.
January 30, 2016
Nice but small
I really like my vest - looks nice, very useful. But the sizing is perplexing - I am 6 feet tall and weight 185 - the XL fits me well. If you weigh 200+ lbs you probably should NOT buy this - even the XL will make it hard for you to breathe.
