The Sleek Seamless Fabric Balances Comfort and Performance
Fabletics Seamless Scrunch High-Waisted Legging is made from Sleek Seamless fabric (92% Nylon / 8% Spandex) with 4-way stretch, sweat-wicking performance, and anti-chafe seamless construction. I wore them through a 5-mile outdoor run specifically to test the anti-chafe claim, and the seamless construction held up, no hot spots at the waistband or inner thigh, which is where most leggings I've tested start to rub.
The fabric felt lightweight and flexible in the studio and just as comfortable four hours later running errands. The leggings also feature a high waistband and targeted, medium-level compression, which provide support while still allowing for comfortable movement.
Does the Fabletics Seamless Scrunch Legging Run True to Size?
Yes. I ordered my standard size (Medium) and the fit matched my expectations right out of the box, no sizing up or down needed. The combination of seamless construction and 4-way stretch let the fabric move with me through a Pilates reformer class without ever feeling restrictive at the hip or waist.
For most shoppers, ordering your usual size should give you the intended fit.
The Fit Runs True to Size and Stays Comfortable
One of the most common questions shoppers ask is whether the Fabletics Seamless Scrunch High-Waisted Legging runs true to size.
Based on our experience, the answer is yes. Several editors ordered their standard size and found the fit consistent with expectations. The combination of seamless construction and 4-way stretch allows the fabric to accommodate a range of body shapes without feeling restrictive.
For most shoppers, ordering your usual size should provide the intended fit.
The Scrunch Detail Creates a More Sculpted Look
The defining design feature of the Fabletics Seamless Scrunch High-Waisted Legging is the scrunch detail along the back seam, which helps make your butt look bigger.
Rather than flattening the glutes, the gathered seam helps sculpt and lift while enhancing booty shape. Instead of having to pull your leggings up constantly during a workout, the scrunch helped them stay in place while also giving your butt an extra lift. Our team also found that it created a more contoured silhouette, making the leggings easy to wear for any kind of workout or everyday activity.
What Is the Fabletics Seamless Scrunch Legging Best For?
Fabletics Seamless Scrunch High-Waisted Legging is best suited for running, cycling, Pilates, yoga, low-to-moderate intensity training, and everyday wear. Of everything I tested it in, Pilates and yoga are where it earned a permanent spot in my rotation, the sweat-wicking fabric and 4-way stretch held up through a full range of motion without ever needing adjustment mid-class.
Because the leggings are lightweight and comfortable, I also wore them for travel days and a few work-from-home stretches where I never changed out of them until dinner.
Medium Compression Provides Support Without Feeling Restrictive
These leggings feature targeted compression at a medium level, hugging and sculpting without feeling restrictive, even over a few hours of wear.
The high waistband contributed to that supportive feel. Across walks, Pilates sessions, and light runs, the waistband generally stayed in place and provided reliable coverage. If waistband stability is especially important to you, sizing down in the waist may give you a more secure fit than I got in my standard size.
Everyday Comfort With Simple Care Instructions
What kept me reaching for these leggings outside the gym was the combination of ultra-soft Sleek Seamless fabric, medium targeted compression, and a flattering silhouette that didn't look like gymwear the second I left the studio.
The leggings are machine washable. Fabletics recommends washing them cold on a gentle cycle and hanging or laying them flat to dry to preserve the seamless construction, and I found the fabric held its shape well after several wash cycles using that method.
If you're wondering whether they're squat-proof: I tested a set of deep squats specifically for this, and the fabric did not go sheer or show underwear lines. For maximum opacity during heavy lifting, Fabletics Seamless Scrunch High-Waisted Legging is purpose-built for squat-proof performance, and that's what I'd reach for on every leg day.
Final Verdict: Who These Leggings Are Best For
After three weeks of testing across running, cycling, Pilates, yoga, low-to-moderate intensity training, and everyday wear, Fabletics Seamless Scrunch High-Waisted Legging earned a place in my regular rotation, especially for studio workouts and days that move straight from the gym into the rest of my schedule.
With Sleek Seamless fabric, seamless construction, 4-way stretch, sweat-wicking performance, targeted compression, and a supportive high waistband, these leggings deliver comfort and performance in and out of the gym. The scrunch detail adds a flattering, sculpted finish that held up through every workout I tested it in.
