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 for specific garment measurements.

Already own 2 other Shak Vests and they're the best. Red should provide high visibiliy in the shoulder seasons on the golf course and on the trail. Known quality of Ibex items makes it easy at this price!

I have an Ibex vest that's three years old and in perfect condition. The problem? I've lost 40 lbs so it fits like a tent. Time for a new one

For a couple of years we'd been looking for a red vest - my husband likes red, and of course it's a great color around Christmas.

Wanted to try a wool vest for cycling/hiking.
Charles T on Apr 27, 2016
Have worked at REI Denver for almost five years and always wanted one of these vests. Great design, unique and appealing texture, American made; what's not to like? Looking forward to years of using this vest!
Theo C on Apr 15, 2016
I like vests; saw a man wearing one - in a medium blue color - who said he'd had it for several years and was very happy with it esp in our climate. and it had not shown any wear. I hope it looks as good on ME.
Victior M on Mar 31, 2016
I recently purchased an IBEX Hooded Indie. I have liked it so much I decided to experiement with other layering systems for the trails or for my Search and Rescue missions. I have taken a liking to vests recently, so this seemed a worthwhile test.
John B on Mar 28, 2016
Have purchased this same item before gifts to faculty members who have been employed with the school for 20 years. Everyone always loves them!
Rebecca B on Mar 23, 2016
I bought on-line, site unseen. I need a replacement for my worn out fleece. I like Ibex products so thought I would give this a try

I wanted a little brighter vest for bicycling in cool weather.
Brian B on Feb 27, 2016
Great experience with Ibex, recently moved from Boston, where your Newbury St store was a delight!
Seems as if in this part of CO, such a garment will be a near perfect wear!
John S on Feb 24, 2016
my husband loves his vest!
Tammy R on Feb 22, 2016
it was an excellent opportunity to try a quality merino vest at a great price! I like the vests to increase core warmth without over-layering the sleeves, causing binding at the bend in the arms. Ideal for biking in cold weather!

Needed a new red vest and I've always loved Ibex gear.
Guest S on Feb 17, 2016
I have the same in black and love it. Looking forward to having the red vest too.
Paul W on Feb 15, 2016
I had one before and I left it in a hotel room closet.

My old IBEX merino wool vest is now frayed and I catch the bottom edge of it on things in my studio so it's looking pretty ratty. But I wear it all winter and it's great.

So I want a new one.

Classic wool vest for casual attire
Peter H on Feb 10, 2016
I cannot say enough about the warmth of Merino wool.
This will be a perfect added layer when I need it.
Mark L on Feb 4, 2016
Nice light weigh with warmth. Also a dressy option for mountain living for my husband.
Kathleen M on Feb 3, 2016
I like the fit on my husband and the blue color

Replacing a lost Shak vest. Worn at least 3x/week and a go-to item for both work and pleasure.

My husband loves vests, but wanted something sporty in wool. It's warm and looks great on him.
Melanie T on Jan 13, 2016
I own one, as does my husband. Great travel pieces - both warm and dressy. Bought one for my son for Christmas.
Robin S on Dec 21, 2015
It's a potential Christmas gift.
VTUltrachick on Dec 17, 2015
multi purpose, liked the red color
Kathleen P on Dec 17, 2015
Looks well made and is quite sharp looking. It is for my 26 yr. old grandson who is a snappy dresser, I think he will like it.
Guest S on Dec 17, 2015
My son sent me the link - site looks great!

I have owned two Ibex vests for years. Wear one them at least three days each week during the fall/winter. Great product
Rodes H on Nov 28, 2015
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.
Guest S on Nov 28, 2015
100% wool. Heavy weight.
mark b on Nov 27, 2015
So practical and versatile.

a gift that my son requested

purchased similar item in past, and loved it.
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.

Charles T on Apr 27, 2016
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....
Does this Scout Jura Vest fit looser than the Shak Vest?

BEST ANSWER: The Scout Jura vest was a gift to my son. He loves it. I sent an XL which looks a little loose,
but gives room for a heavy sweater. He is 6ft tall and weighs 198 pounds.

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.

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
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 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.

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
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.

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.
