How the Sculpt Scrunch Bum Bike Short Fits
The Sculpt Scrunch Bum Bike Short is designed to be true to size with medium compression. That means it holds you in without feeling restrictive, making it a solid choice for weightlifting, cardio, or everyday wear.
The fabric is super stretchy with 4-way stretch, so it moves with you during squats and lunges. The body-hugging fit accentuates your curves, while the scrunch bum detail adds a subtle lift. There is no front seam, which reduces visible lines and improves comfort.

Choosing Your Size
The brand recommends going true to size based on the medium compression level. The model Lea wears a size M; she is 5'9" with a 30.5" waist. Use that as a reference point for your own measurements.
Available sizes are S, M, L, and XL in the color Grey. If you are between sizes or prefer a less compressive fit, you may want to size up. The fabric has enough stretch to accommodate a range of body shapes, but the medium compression is designed to stay put during movement.
Fabric and Care Considerations
The shorts are made from 80% Nylon and 20% Spandex, which gives them a sweat-wicking, soft feel. They also come in sustainable 100% compostable packaging.
To keep the fabric and compression lasting, wash in cold water and hang dry. Avoid fabric softeners, as they can break down the spandex over time. The squat-proof and 4-way stretch properties hold up well with proper care.
When This Short Works Best
The Sculpt Scrunch Bum Bike Short is ideal for high-movement workouts like weightlifting, HIIT, and cycling. The medium compression and squat-proof fabric give you confidence during deep bends. The scrunch bum detail adds a flattering touch without sacrificing function.
It also works well for casual wear or meal prepping, as the fabric is soft and the no-front-seam design reduces bulk. If you need a short that transitions from gym to errands, this is a practical choice.
