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.

Hoping that I will enjoy these as much as I enjoy the balance briefs...
Helene g on Aug 20, 2016
I want underwear with full coverage and the balance natural materials. I want underwear that fits and meets my needs, not the needs of men looking at lingerie catalogs.

I ordered these because I'm looking for something higher than a bikini brief that will be easy to dry while traveling for several weeks. I've never tried boy shorts and have my doubts about whether they will work for someone like me but it's worth a try.
Sharon R on Aug 8, 2016
Comfy, no panty lines! Next best thing to a thong but warmer in the winter! These are also my go-to underwear when biking. Now if only Ibex would make these longer (say mid-thigh) they would really be the best thing ever for biking underwear as I prefer no padding and don't like spandex.
Carol H on Jul 23, 2016
Because they will look hawt on my girlfriend
Anson C on Jul 22, 2016
Because I have at least six pair of the briefs and thought I'd try these... Might help with unsightly panty line

nude color, trying different cut. other style underwear did not hold well.
kristina p on Mar 5, 2016
Want to compare these to my Icebreaker boy shorts; love the style, very warm and comfy.
Elaine S on Feb 19, 2016
Going for 8 days backpacking trip. Another reviewer said it dips at the back which is a nice design detail in my book. So thought I'd try it.
Guest S on Feb 17, 2016
I am a cyclist and these shorts have always seemed attractive to me.
Sierra R on Feb 11, 2016
Love the durability and breath ability of wool. May be worn for several outtings before washing.
Lyndal H on Feb 11, 2016
I was looking for a some underwear for underneath a pretty short dress. This will keep my butt cheeks off the chair!!
Lisa U on Feb 7, 2016
I love these for wearing to bed. I really relied on these and the old style spaghetti string camisoles for when I was having hot flashes at night and I found they were great for sleeping in tropical climates. I don't wear them under clothes that much but i did wear the camis under everything. Please bring back the old style camis!!!
Holly H on Feb 6, 2016
I Have heard awesome things from coworkers
Megan R on Feb 2, 2016

Comfortable, good for travel (feel cleaner while wearing them than polyester.)

SCVT on Jan 22, 2016
To wear while paddleboarding. More breathable than bathing suit bottom under my wet suit.
ski girl on Jan 16, 2016
I love wool underwear and wanted to try a pair of yours. So far I've only found one brand that I like, so I'm keeping my fingers crossed...
Jean the hiker on Jan 15, 2016
Very warm and comfortable.
Alexis S on Jan 15, 2016
My wife owns other colours of these and prefers the fit to other outdoor base layer options.
JamesC on Jan 15, 2016
great addition layer
Tatiana E on Jan 14, 2016
decided to give them a try - the most comfortable underwear i own!
emma s on Dec 15, 2015
I love wool underwear! If you haven't tried it, consider it. Wears well, not itchy like you might fear, warm against the body. Haven't tried Ibex underwear yet but have tried all the other wool brands. Consider it a taste test.
Susan M on Dec 8, 2015
possibly good for my disabled sister whose undies tend to ride up
Lisa M on Dec 4, 2015
Worlds best underwear
Elisa M on Nov 27, 2015
Same as above
Marcia B on Nov 25, 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.
Linda W on Nov 24, 2015
I wanted to try the wool underwear from Ibex
Cago on Nov 16, 2015
Fast-drying--perfect for travel--much better than synthetics--and (we hope) long-lasting!
Janice M on Nov 9, 2015
Took two pair to Paris for a week with other briefs and just kept washing these out and drying them overnight on the radiator. Warm, soft, very comfortable.
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.

I have ordered there and they are great for wicking sweat and odor, highly recommend!

Sharon R on Aug 8, 2016
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
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.
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?
JaneA on Oct 12, 2015
W's Balance Boy Short

W's Balance Sport Bra

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.
Are these low rise? I tried the Balance Brief and it was way, way too low rise for me. Do these have a higher rise than the Balance Brief?
Gwen J on Aug 21, 2016
BEST ANSWER: Hi there, the rise for the Boy Shorts is 6" for small, 6 1/2" for medium and 7" for large. This measurement is from the top of the waist band to the crotch seam and is the same for front and back.
I hope this is helpful.
I will be hiking the Appalachian trail, want to know if these would be the best type of underwear to use under hiking pants?
Linda S on Jun 22, 2016
BEST ANSWER: I wouldn't say that they are the best underwear. It depends on what time of year you're doing the hike. These are nice for colder climates to keep your bum warm. But I found that the synthetic/spandex type of undies is the best for serious hiking because they dry faster than wool.
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.

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.

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.

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
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'.

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.

They should dry fast.
The material is okay, but they lack structure in the waist and leg openings. The waistband in back seems to dip down too low, giving them a "plumber" feeling. I like the idea, but it needs a little work. Still, I will keep them for backpacking and kayak trips. Very lightweight, and they should dry fast.

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.

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.
