June in South Carolina means you are drenched before your second horse. You are making clothing decisions at 5:45 in the morning based purely on survival instinct, and “do these breeches breathe” suddenly becomes the most important question in your life. I have ridden through enough brutal summers to have strong opinions about this, and one question I keep getting asked is whether leggings — specifically the FRE Define Leggings — are a legitimate flatwork option or just wishful thinking dressed up in technical fabric.
The honest answer is: it depends on what you are asking them to do. Here is the full breakdown.

What the Define Leggings Actually Are (And Are Not)
Let me be precise here because I think people get confused when they see leggings listed under a breeches category.
The Define Leggings are a legging-cut riding pant. They do not have a knee-patch silicone grip. They do not have the same structured waistband as the Lux line. They are slimmer through the hip and thigh than anything else in the FRE breeches range, and they are cut for movement rather than grip. FRE is upfront about this in their own product notes: these are best for flatwork, schooling, and barn-to-saddle days.
At $85, they sit between the sale-priced Heavyweight Winter Breeches and the Lux line, and they come in six colors — Black, Navy, Charcoal, Raspberry, Ocean, and Periwinkle. The color range is more limited than the Lux, but the options are clean and versatile.
What they give you that traditional breeches do not: a waistband that sits flat without digging in, zero bulk through the inner leg, and a fabric weight that feels genuinely appropriate for a ninety-degree morning. You are not fighting your pants while you ride. For flatwork, that is not nothing.
Who these suit:
- Riders doing dressage-focused flatwork or quiet schooling
- Anyone doing ground work, longeing, or in-hand work where you need free movement
- Riders who run hot and hate the feeling of structured waistbands
- Barn days that involve riding but not jumping or hard cross-country
Who should look elsewhere:
- Jumpers who need the knee-patch grip on course
- Riders doing serious lateral work where inner-leg adhesion matters
- Anyone showing in a sanctioned ring (not show-appropriate)
- Riders who need a structured seat for sitting trot collections or deep dressage work
That last one is worth expanding on. If you are working on a sitting trot or anything that requires your seat to stay anchored and sticky in the saddle, the Define Leggings will feel noticeably more slippery than a full-seat or knee-patch breech. They are not dangerous — you are not going to slide off — but you will work harder to maintain your position than you would in a grippy seat. For relaxed flatwork or posting trot, it is a non-issue. For a serious dressage school with extended sitting work, you will notice the difference.
How They Compare to the Lux Line for Summer Flatwork
This is the real question, so let me put it plainly.
The Lux Zip Breeches at $95 are FRE’s everyday workhorse. They are lightweight enough that in previous posts (and in the saddle) I have called them close to a legging feel. So why would you spend $85 on the Define Leggings instead of $95 on the Lux Zip?
The difference is real even if it is subtle. The Lux Zip has a defined waistband, a zip-front closure, and a knee-patch grip panel. It holds its shape through a full day of riding. The Define Leggings have a pull-on waistband that is genuinely softer and flatter — no zip pressing against your lower belly when you fold at the hip, no structured panel around your waist when you are trying to breathe in heat.
For some riders, that difference is significant. For others, the Lux Zip already feels comfortable enough that there is no reason to switch.
Here is a quick comparison:
| Feature | Define Leggings | Lux Zip Breeches | Lux Hybrid Full Seat |
|---|---|---|---|
| Price | $85 | $95 | $95 |
| Waistband | Pull-on, soft | Structured + zip | Pull-on |
| Grip | None | Knee-patch silicone | Full-seat silicone |
| Best use | Hot-weather flatwork, schooling | All-day everyday riding | Dressage, deep-seat work |
| Show-appropriate | No | Yes | Yes |
| Fabric bulk | Minimal | Light | Light |
The Lux Hybrid Full Seat is worth mentioning here too. It has a pull-on waistband like the Define Leggings, but it adds full-seat silicone grip — making it the better choice if you want a pull-on feel but need grip for more technical work. At $95, it is only $10 more than the Define Leggings and gives you more versatility across riding types. If you are on the fence and you jump or do serious dressage, I would lean toward the Hybrid Full Seat.
But if your focus is flatwork in heat and you do not need the grip? The Define Leggings earn their place.

What I Actually Use Them For (Real-World Notes)
I have been wearing the Define Leggings for flatwork schools and in-hand sessions, specifically on my horse’s hotter days when I want to keep the work quiet and deliberate. A few specific observations:
The inner-leg feel is the biggest win. No bulk means your leg sits closer to the horse, which I notice most in dressage-style work where subtlety matters. There is less fabric between your calf and your horse’s side, and for light lateral aids that is genuinely useful.
The waistband does not move. Despite being a pull-on style, it stays put through posting trot, two-point, and transitions. It does not roll down or creep up. This is not a given in leggings — plenty of athletic leggings fail this test on a horse — so it is worth calling out.
They are not for arena footing days. The day I wore them for a longer lateral-heavy school in collected work, I felt the absence of grip. Not unsafe, but effortful. On an easy hack or a light conditioning school, they are perfect. For a serious flatwork session that demands a steady, planted seat, I reach for the Lux Hybrid Full Seat instead.
Sizing: The Define Leggings run true to size in my experience. Unlike the Lux breeches, which run slightly long (relevant for shorter riders), the legging cut with its hemmed ankle sits clean without needing adjustment. If you are between sizes, I would size up for comfort through the hip; the fabric has good stretch but these are not a compression fit.
The color options are conservative but smart. Black and Navy are the obvious everyday picks. Raspberry and Ocean are good if you want some personality without going loud. I have the Charcoal, which photographs dark enough to read as black in low light but is slightly softer in person — a good choice if you already have black and want something that works with the same belt and boots.
Speaking of belts — the Define Leggings have a clean waistband that works with the FRE Bit Belt or Surcingle Belt if you want a finished look for client-facing barn days. It is a small detail but it matters when you are trying to look put-together while also surviving the heat.
The Verdict: Leggings for Flatwork — Yes, With Clear Conditions
Can leggings replace breeches for hot-weather flatwork? Yes — if you are clear-eyed about what flatwork means in this context. Quiet schooling, light lateral work, in-hand sessions, conditioning hacks, barn-to-saddle days: the Define Leggings handle all of that well and handle it more comfortably than a structured breech on a brutal summer morning.
They are not a replacement for your Lux breeches across the board. They are a heat-specific tool for a specific kind of riding. If you understand that going in, you will not be disappointed.
If you are newer to thinking about this kind of gear decision and want to dig deeper into how I structure my summer riding and training approach, I talk through a lot of this on the podcast — including how I adapt flatwork expectations in extreme heat.
For riders who do most of their summer work on the flat and want to stop dreading putting on breeches at 6 a.m., these are worth the $85.
