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've worn these for several winter runs and cross country skis now and absolutely love them. The most recent run was on New Year's Eve and even standing around before and after the run (20 degrees F) my legs were warm, and yet did not get overly warm during the run, which is something i really notice. These will make my winter even more enjoyable!

Ibex's Best Idea Yet!
I live at 10,400 feet in Colorado and I have worn these pants everyday since they arrived! Performance is top notch for power walking to computer work and everything in between. Never get too hot even when in the house with radiant floor heat on...can go in & out all day and not have to change pants! Pet hair (dog, cat, horse) does not cling and if you get a bunch of fur on them it brushes off q

the best!
I wear these with a cashmere tunic and boots everwhere - I would like them in brown and dark grey, too.

Tights that go the distance!
It's hard to find a product that can truly go the distance when training for a marathon- but the Energy Tight seems primed for the job! They are formfitting, yet somewhat forgiving with their woolly texture. The wide waist band rests comfortably above the waist, and the legs stay in position regardless of the hills ahead! A definite gem, sure to be a part of all my future runs!

Worth every penny!
I love these! I've worn these several times for cold morning runs and my legs stay nice and warm without the bulk. If you are active outdoors during the winter- ski, run, cycle - you must have a pair of these. Already recommended these to my runner/cyclist sister!

Perfect running tight
The energy tight is my new favorite thing to wear running. In fact, now that I have them, I can't imagine running in anything else during the cold winter months. They are the perfect weight for running when it's 30 degrees or below. They are not constricting like some other running tights I've had in the past, yet also keep their shape and don't end up sagging or slipping. I can't recommend this e

Completely awesome
I live in interior Alaska and have a hard time finding a mostly wool base layer that is sufficiently thick and durable. These tights are great and flattering for regular everyday wear, but also are an excellent base layer for x-c skiing, snowshoeing, and running in cold temps. I've only had them about a month but am pretty sure these tights will last a lot longer than most of the thinner base lay

I absolutely love these! I bought them for outdoor walking/jogging. Great winter weight fabric, comfortable, washable. Just awesome!

Oh yeah, wool running tights!
Ibex's Energy Tight is awesome! I've only had them for about a week, but I'm in love... The fit is great and the fabric (unsurprisingly) amazing. I was especially impressed when it was covered in snow and I didn't feel wetness or clinginess (a result when wearing tights made of other fabrics) at all (neither during nor after working out).

The only thing I have to criticize is the same as others h

All-time Favorite tights
I have been running for years and am so glad to have found these IBEX tights. They are perfectly snug, even after daily wear and numerous washes. The Energy Tight has made winter running, hiking and x-country skiing so much more pleasurable.
I've recommended these to all of my friends!

Thank you IBEX for wonderful design!
