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

Worlds best underwear
Elisa M on Nov 27, 2015
I tried a pair of these out in some gnarly back-country winter climbs and they performed well. I was dry, warm and very comfortable. I liked them so much, I ordered two more pairs for an upcoming adventure in Iceland.

Fast-drying--perfect for travel--much better than synthetics--and (we hope) long-lasting!
Janice M on Nov 9, 2015
Been wanting to try a pair for a while.
penny on Nov 5, 2015
This is my favorite underwear for travel. Very comfortable in cold and hot weather. I wash at night and it's dry in the morning
Sandra M on Nov 4, 2015
Great fit. Comfortable. Anti microbial.

Want to have a boy short style undie with flat lock seam
Kwok Kin C on Oct 25, 2015
I have a skirt that is short enough that I have to wear tennis undershorts with it. Ends up that it was really comfortable & I want to try these!
Carol C on Oct 21, 2015
Love boy shorts for hiking and biking- great reviews- can't wait to try them!
Guest S on Oct 19, 2015
Looks interesting and winter is coming.
Megan P on Oct 18, 2015
I have ordered there and they are great for wicking sweat and odor, highly recommend!
teresa a on Oct 12, 2015
I'm hoping I can wear these under dresses and not have panty lines.
Hannah K on Oct 11, 2015
Very comfortable. You just don't have to think about these. I always choose them first so I always run out and have to keep washing them. I just bought more.
Teresa E on Sep 24, 2015
I need something substantial that will breathe. Hope this is the garment for me!
ELAINE O on Sep 20, 2015
They are so comfy: nothing tight around the legs!
Donna T on Sep 19, 2015
For comfort and use when hiking in a kilt.
Roger D on Sep 15, 2015
Wanted to try the boy shorts , liked the style and color.
Robin M on Sep 13, 2015
Hiking the AT in March, need to get my base layer.
Lisa H on Aug 30, 2015
I bought these to replace another pair that wore out. Took a lot of years to destroy the first pair. They do ride up a bit with a lot of walking: just not long enough for my shape. I like them under jeans or skirts in the summer. Prefer the briefs for longer hikes.
Anne C on Aug 30, 2015
I ride horses a lot and the comfort of this underwear is unparalleled for no chaffing and overall comfort.
DuLane C on Aug 27, 2015
great fit, comfortable, cool in summer, warm in winter
Stephanie W on Aug 25, 2015
have loved my several years old Ibex undies - need new ones
Elaine S on Aug 19, 2015
Interested in seeing if this will keep my thighs from rubbing together under a skirt. TMI? Also intersted in wool as underwear.
Kirsten L on Aug 15, 2015
always looking for a natural underwear. Trying these out to see if these might be what I'm finally looking for!
Lauren W on Aug 13, 2015
I have something from athleta that is just like this but all synthetic. It's hot. I am hoping that this would be cooler. I wear these kinds of shorts under short skirts. Also nice to wear as summer sleeping bottoms.
Yuko U on Aug 8, 2015
I wanted to try your wool undies and need a skin color pair for wearing under white pants. I hope I love them!
Tammy R on Aug 4, 2015
I wanted a short to wear under my favorite Ibex active dress while hiking.
Laurel R on Aug 3, 2015
I think it would be nice to have wicking shorts. I really like my sport bra and want to try out the bottoms too!
Kristen J on Jul 29, 2015
Looked fun to try with the sale. I've been wanting to try merino underwear.
Julie S on Jul 26, 2015
to wear under skirts, and to try it
beanie on Jul 23, 2015
I have been looking for a natural-fiber underlayer for shorts (for running and tennis) that does not show panty lines.
Jessica H on Jul 22, 2015
So comfortable, fits like skin. Nice for hiking to a lake, swimming and for anytime under s skirt.
Virginia H on Jul 14, 2015
I have one pair already and LOVE them. For me, these are best under snug jeans, as I have large thighs which causes the boy shorts to roll unless they're held in place by jeans. Comfy, soft, awesome.
Elizabeth B on Jul 14, 2015
Good fit. Soft. Helps flatten the tummy a bit :)
Mariana S on Jul 13, 2015
Simple light weight shirt to layer or wear on its own.
Susanna H on May 10, 2015
I like the bra so much I had to try the bottoms
Holly H on May 9, 2015

My Wife loves these
William B on Apr 21, 2015
I've never tried the boy short and I wanted to give it a try
Marie B on Apr 21, 2015
I'm hoping for a boyshort for hiking/backpacking/cycling that has a long enough inseam that it doesn't ride up or create unsightly lines under tight fitting clothing (cycling shorts, running tights, tight fitting baselayers).

why don't you make granny panties?
Nancy R on May 30, 2015
BEST ANSWER: Hello I will pass this suggestion on to our Designers. Thanks
Why no XS offered? Do they run small? I have the same question for balance briefs
A shopper on Aug 3, 2015
BEST ANSWER: Hello the Balance Shorts to run small we suggest sizing up. As for having them in XS we can pass this along to the Designers. Thanks
I am a true size 4 but prefer a Medium in Ibex Bras and Briefs. Should I size up in the Boy Shorts as well?
A shopper on May 8, 2015
BEST ANSWER: I wouldn't size up unless your upper thighs are very large in proportion to your waist, in which case instead of ordering according to your waist size, you might want to go up one size. I hate underwear that binds, but I find these Ibex boy shorts very comfortalbe, and they're true to the measurements on the Ibex size chart. They don't give me a panty line, even with slim jeans.
Does it shrink after washing? Is this compressive?

BEST ANSWER: It does constrict some after washing, but since I don't put them in the dryer, I don't know if I can fully answer the question about shrinking. I have accidentally put other merino pieces in the dryer without any shrinking, so even though I wouldn't suggest doing it regularly, I doubt you'll do any serious damage either. The material isn't compressive, so even though they fit true to size, if you want them to be super tight I would suggest buying a size smaller than what you normally wear.
I bought these - nice but the seam is
too thick to wear under leggings. Please make boy shorts without that thick seam or if you have to have a seam, finish it with lace or something that does not show, please?
K E on Nov 1, 2015
BEST ANSWER: Hello thank you for your suggestion we will pass this along for you.
When will this be back in stock?
A shopper on Jun 18, 2015
BEST ANSWER: Hello we will have the W's Balance Boy short back in stock on our Fall/Winter line which we will launch the first week of September. Thanks

Couldn't be happier
I love these and the briefs! They are attractive, but comfortable in every circumstance. I ordered a few pairs and have been hiking, bike-riding, and climbing in them. I've never had such a comfortable pair of underwear. They are almost life changing.

Cute base layer
These shorts are really cute and super comfortable. Great to wear as base layer to stop chafe and add warmth under river shorts. Fun to wear with every day clothes too. Black color is not transparent so you can wear them as shorts or a swimsuit if you like.
April 18, 2015
typical boy short problems
These do ride/roll up, just like other boy shorts. They are also thick. Too hot to wear in the summer or under thin/ light clothes.

perfect for warm weather
I bought these shorts to wear under dresses during the warm months. I wanted something that would make me feel more comfortable when, well, for lack of better words, sweaty! These wick away moisture and are smooth under a skirt. I will definitely be buying more.

I like these a lot! Read a review that said they worked well as a swimsuit in a pinch (would work well with one of the ibex bras on top too) which sold me. They're definitely a thick enough material to pass I'm public. I think most underwear sold to women today is uncomfortably tiny and these are much more to my taste. Boyfriend says they're his new favorite too! These boy shorts don't have the same sizing issues as the bra. I'm an XS in ibex pants and the S in these fits perfectly. The M is ok, but a bit loose.

I gave these to my 24 year old daughter who wears them constantly. She wears them under skirts to provide coverage like a skort and under pants/shorts for comfort and if they were cheaper I'd buy her a dozen.

Comfy, soft, but bottom edges roll
I love these and have 2 pairs. They're wonderful, but with my curvy thighs, the bottom edges roll up. It's no big deal under jeans that keep them in place, but I couldn't wear them under knits or thinner fabric.

Where have you been all my life?
Finally!! Underpants that actually cover the important bits! Extremely comfortable; no riding up - or down. I bought a few pair for working out- wicking moisture, breatability and all that, but they are so comfortable, I have searched for more wool underwear to wear all the time! So why three stars and not five? The price is steep and one can find comparable garments for 40% less on sale..... Just sayin'.

not enough room in the rear
These are okay but by the end of the day they are riding up in the back. I have a fairly muscular behind but not that big so I'm surprised these shorts fit me so poorly there.

I love this underwear. Does all the good things wool does.
