It seems like I’ve had a lot of people ask me lately about breech sizing, especially in regard to Aztec Diamond. I decided to pull out all of my breeches (sadly my collection has dwindled since last fall, but I still have 11 pairs across several different brands. Caveat – a couple were given to me and either I don’t know the brand or I haven’t really worn or looked closely at them yet, so I did not include those here) to measure, compare, and photograph. I’ve tried to put as much information in here as I can think of regarding each brand, how they fit, how they wear, and main features. If there’s something I didn’t cover, please feel free to ask and I’ll add it in. Hopefully this helps someone out there! I took pictures of one pair of each brand so you can see what they look like on a real person vs a model. It’s very interesting to see pictures next to each other like this… you can really tell which ones are most flattering to me vs which ones are not!


2 pairs of low rise Trophy Hunter front zips, one knee patch euro seat (size 30R) one full seat (size 30L)

Fabric: 73% cotton 20% polyamide 7% lycra
Measurements (knee patch pair):
Waist: 15.5″
Hips: 19″
Rise: 11″
Inseam to bottom: 24″
Compared to 30L Trophy Hunter full seats: the full seats are 1/4″ smaller in the waist, hips 1″ smaller, inseam 2″ longer, rise is the same.
Features:
Velcro bottom
Two pockets
Belt loop size – 2 1/8″
no euro seat lining
Stain resistant (on a scale of 1 – 5, with 1 being least resistant and 5 being most resistant): 2
Do they stretch out with wear: Yes
Are they stiff or soft out of the wash: Stiff, I usually toss in the dryer on no or low heat for a minute after they’re dry to soften them back up.
Do they dry quickly: Meh. Average.
Are they thick or thin: on the thinner side but not particularly thin
# of wears (approx): My knee patch pair I bought new last spring and have worn approx once a week since. The full seats I bought used and have worn twice myself.
Is there any fading? Yes. It’s not very noticeable with the tan obviously, but the green have already faded a good bit.
Is there any pilling? Not on the knee patch. There is a little pilling on the full seat material of the tan pair.
How well do they hide thigh cheese: Pretty well.
Any fit issues: The waist is a bit gappy on me, I have to wear a belt or they constantly slide down my hips. Especially since the more I wear them, the more they stretch and the worse they sag. Really a size 28 fits me best in the waist, but then the thighs are obscenely tight, so I buy to fit my thighs and deal with the gappy waist. Also – they always do that weird pointy thing to my butt. Always.

one pair of size I-42 and one pair of size I-44

Somehow I have two different sizes of these. The smaller ones were purchased when I was thinner, and although they’re tight now, they still fit. I know they’re two different models but they’re so old I don’t remember the names of them. If I’m able to find out I’ll come back and update.
Navy size I-42
Fabric: 90% polyamide 10% elastane, Euro seat lining 90% polyester 10% elastane.
Measurements:
Waist: 15″
Hips: 18″
Rise: 10″
Inseam to bottom: 27″
Inseam to start of sock bottom: 21″
Tan size I-44
Fabric: 90% polyamide 10% elastane, Euro seat lining 90% polyester 10% elastane.
Measurements:
Waist: 15.5″
Hips: 19″
Rise: 10″
Inseam to bottom: 27″
Inseam to start of sock bottom: 21″
Features:
4 pockets on the navy, 2 pockets on the tan
sock bottoms
lined euro seat for comfort/anti-chafing
belt loop size – 1 3/4″
silicone knee patches
Stain resistant (scale of 1-5): 4
Do they stretch out with wear: No
Do they dry quickly: Fairly quickly
Are they thick or thin: somewhere between average and a little bit thick
# of wears (approx): On the navy pair – a lot. I’ve had those for years and worn the heck out of them. On the tan pair – probably a dozen wears.
Is there any fading? The navy pair has just finally started to get the first beginning signs of fading.
Is there any pilling? At the back of the knee on both pair.
How well do they hide thigh cheese: Pretty well. The navy more than the tan, obviously. The fabric has an almost elastic feel to it that kind of helps to smooth out your more unfortunate areas.
Any fit issues: With the navy pair, no. The tan pair are just a hair big in the waist, so they can slide down a little without a belt. I’m really kind of in between an I-42 and I-44 right now.

Stain resistant (scale of 1-5): 4
Do they stretch out with wear: No
Are they stiff or soft out of the wash: Soft
Do they dry quickly: Very quickly

# of wears (approx): The Houndstooth I got in the summer and have worn a lot since. They’re probably my favorite pair. The Flight I just got and have worn twice.
Is there any fading? No.
Is there any pilling? No.
How well do they hide thigh cheese: Pretty darn well.
Any fit issues: None, honestly. They fit like they were made for me and I find these to be the most comfortable.

Fabric: main body 65% cotton, 30% poly, 5% elastane. Seat – 88% poly, 12% polyurethane.

Are they thick or thin: on the thin side
# of wears (approx): Probably about equal on both pairs, around a dozen times each.
Is there any fading? Not yet.

How well do they hide thigh cheese: Not that well.
Any fit issues: I don’t think they’re very flattering around the tummy area, but they’re comfortable to wear.

one pair of Sit Tight Supreme full seat size Large

We have dubbed these “The Unfortunate Crotch Pants”. Luckily the crotch looks normal when you’re in a riding position, it’s just not so cute when you’re standing around. I was in between the size measurements of a Medium and a Large so I sized up rather than possibly end up with a gross thigh situation. That makes them a bit big for me in the tummy area.
Fabric: body 90% nylon 10% spandex, seat 82% PU 18% poly
Measurements:
Waist: elastic. 14.5″ unstretched, 16.5″ stretched
Hips: 19″ unstretched, 20″ stretched
Rise: 11.5″
Inseam to bottom: 29″
No other pair in this brand for sizing comparison
Features:
Neither velcro nor sock bottom – breeches taper to ankle
No pockets
Full seat is lined with Coolmax material
Belt loops: 2.25″
Stain resistant (scale of 1-5): I have not worn them yet so can’t comment on that. Will update after I wear them.
Do they stretch out with wear: see above
Are they stiff or soft out of the wash: see above again
Do they dry quickly: keep seeing above
Are they thick or thin: Thin. Like I don’t think I would wear these without an underlayer , but maybe I’m being paranoid. I’m not wearing an underlayer in the photo.
# of wears (approx): None.
Is there any fading? See first response.
Is there any pilling? Keep seeing it.
How well do they hide thigh cheese: Actually, for a thin white breech – better than you’d think. They are decently flattering on me (aside from the crotch), for what they are. I wouldn’t go so far as to say they’re actually all-out flattering, but they aren’t bad.
Any fit issues: The big hips/tummy in comparison to thighs. Wish they were a little smaller up top. Also, they’re quite long. I’m 5’6″ and they work ok for me but I’d imagine a short person would have a lot of extra fabric to deal with.
