Wool Type +


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

That Collar! That Pocket!
I think I get it. The pocket on the side, the range-of-use. After a well thought out mis-start, I also think Ibex got it, too.

I was one of no doubt many who fell in love with the versatility, the durability, the outright comfort of the Shak Jersey, and lobbied Ibex to make a vest version. Their first attempt�the Kilometer�was not well received. I liked mine as a mid-layer for hiking/back

Flattering and Warm - win win
The gift recipient loved his new vest. Beautiful color and fit. He had a hard time taking it off but his new ibex hoody sweatshirt also beckoned him.

love shak baby
Just in time for fall. This vest has moved to the top of the do everything list. The shak material is light enough to comfortably layer under a jacket for the ride to work and strikes a great balance between added warmth and breathability to keep you from overheating. No need to take it off once at work, it is casual/ stylish enough to wear the rest of the day. I am looking forward to using backco

Excellent Vest
This vest is perfect to use in conjunction with a leather jacket, and the neck collar keeps my neck warm especially on a cold, windy day!

It's one of my favorites
This is one of my favorite Ibex items. The design is superb. Meets my expectations on form, fit and function.

Excellent all around warmth and comfort
Excellent Ibex quality and service. I easily get hot but this vest is great, perfect warmth and very breathable. Just wished the price was a little lower but sure I will get plenty of use out of it.

Very sharp
This is a great piece. I have it in red--it's just on the edge of too loud, but it's extremely well fitted (I have the medium, I'm 5'10" 155 lbs), and I wear it with office wear and it's very very sharp. I have strongly considered a second one in another color because of it's look and versatility. One of my favorites of my several Shaks.

two thumbs up
This is one of the best pieces I have ever owned.
Works well for everything: cool/cold weather MTB, climbing, skitouring, nordic skiing, beer drinking, sleeping under a tree, even under the trenchcoat if you have to spend a cold day in the city.
