Features

The waistband stays flat when you bend
Thin top elastic flips over the moment you hinge forward. The 4.5-inch contoured panel spreads compression evenly across your midsection, so there's no edge to roll and nothing pinching your ribs.

The fabric stays solid at full stretch
At 280 GSM, the double-knit interlock has enough yarn density to stay opaque at the bottom of a deep squat, even in bright gym lighting.

The pocket locks your phone to your thigh
A tension hem across the top of each 7.5-inch pocket holds your phone flat against your leg, so its weight doesn't drag the waistband down while you move.
Snaps Back, Wash After Wash
High-recovery elastane keeps the knees from bagging and the waistband from stretching out, even after repeated washes.
Resists Pilling & Pet Hair
The tight, smooth micro-nylon knit resists inner-thigh pilling and lets dog and cat hair brush right off.
Non-Roll 4.5-Inch Waistband
A wide, dual-layer contoured panel with no thin elastic at the top edge. It stays flat above your navel through squats, hinges and burpees.
280 GSM Squat-Proof Fabric
A dense double-knit interlock that stays fully opaque at full stretch and hides texture. Ultra-matte, never shiny.
Two Deep Phone Pockets
7.5-inch side pockets with a tension hem keep a large phone flat against your thigh while you run, with almost no bounce.
Seamless Front & Flatlock Seams
No vertical front seam means no camel toe. Flat, 6-thread seams lie smooth against skin to reduce inner-thigh chafing.
How to use it
- 1
Pull them up
Grip the wide waistband and pull them up over your hips. Give it a firm tug; the compression is real.
- 2
Smooth and load up
Smooth the waistband flat above your navel and drop your phone and keys into the side pockets.
- 3
Move all day
Squat, run, lift or head out for coffee. No pulling up, no phone bounce, no mirror checks.

Care & safety
- Machine wash cold, inside out, with similar colors. Skip fabric softener, which coats the fibers and weakens stretch recovery.
- Hang or lay flat to dry. Avoid tumble drying on high heat and ironing to keep the elastane snapping back like new.

Questions
Is there a seam down the front?
No. The SculptLock 280 has a smooth seamless front panel with a diamond gusset, so there's no vertical front seam and no camel toe.
Will a large phone fit in the pocket?
Yes. Each side pocket is 7.5 inches deep and fits a 6.7-inch Pro Max-size phone, including in a rugged case, with a tension hem that keeps it flat against your thigh.
What's the inseam length?
The inseam is 25.5 inches with an ankle taper. On most wearers it hits at the ankle bone. On shorter wearers it may sit slightly longer without heavy bunching.
