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

WOW, I'm hooked
It's products like this that are making my IBEX addiction a real problem. This jacket arrived a few days ago and I can't take it off. The fabric's incredible: flexible, form fitting, zero bulk, flattering accent lines/seams. A small fits perfectly (5'5", 115lbs). I'm trying to expand beyond grey and black in my winter wardrobe: the navy is almost black really but softer, warm and very flatterin

Work or play in style
I own five of the Energy full zip tops. I mostly wear them over a blouse at work while I am teaching. I get many compliments when I wear them. The most common comments are the lines drape beautifully, it looks great and it is really dressy. I am middle aged and love the relaxed fit (I am an XL size). It is super comfortable and I wish Ibex made more colors. I would like to suggest a beautiful gree

More colors for spring please!
I love this top! I wear it for hiking and climbing, yet it's stylish enough to wear over a top at the office and out to dinner. Ibex, please please please bring this back in the spring in lighter shades--it would be the perfect spring cardigan! I would love to have this in off-white or rusty red or pretty much any color...

Like it more everyday!
I've worn this nearly everyday since I got it and like it more and more. At first I wasn't sure I liked the look of the pockets and the looser fit, but it's super comfortable and good for layering. I also like the merino/nylon/spandex blend--very comfortable material. I haven't washed it yet, however, but other Ibex products that I have launder well, so I don't expect problems.

Wonderful sweater
I really love this sweater. I have all four colors. They are perfect for layering. They were great while traveling in Europe for wearing during the cool mornings, stuffing in a backpack during the day, and pulling out wrinkle-free for the cooler evenings. I've worn them hiking in the Alps, out to nice dinners, on long plane rides, to church, to the gym, and everywhere in between.

Great Layer
Bought this as a layer for hiking, but used it just as much for every day wear, receiving no end of compliments. Flattering lines; comfortable pockets; sturdy feel.

my favorite full zip!
I purchased this as one of a whole bunch of full zip tops, as I was looking for the perfect one. Immediately I knew this was it- clean lines, a little strech, great weight. It was great for my larger frame.
I ordered another one!

I wish I was wearing it right now.
I've been wearing this both around the house for warmth and in lieu of a sweatshirt at the gym. It's comfortable and more flattering than a sweatshirt. Would also be excellent under a ski shell for colder days instead of a fleece jacket. I also ride a motorcycle and I plan to wear this in the spring/fall for cold or rainy rides.

Color better in person
I wanted another Energy Full Zip but the one available in my size was the Burnt Rose color which I didn't like so much, too bright for me. Since I was ordering other items I thought I would order this color anyway hoping it would not be as bright as it appears on my computer monitor. This color is not bright and is gorgeous on me, dark hair olive skin. My initial hate for this color turned into
