Find your perfect fit in the Women's AeroPro 3 Split Shorts. This guide explains how to measure, what to expect from the 3-inch inseam and split design, and who this style works best for.
Quick answer
For the Women's AeroPro 3 Split Shorts, order your usual running short size based on hip measurement, but expect a closer fit through the waist and thigh due to the 3-inch inseam and half-side split design.
Why the 3-inch inseam changes how you size
A 3-inch inseam is shorter than a typical 4- or 5-inch running short. The half-side split adds extra freedom of movement, but it also means the shorts sit higher on the thigh. If you prefer more coverage or have larger thighs, you might want to size up for a slightly looser fit, especially if you are between sizes.
The waistband fit matters more than the number
The AeroPro 3 Split Shorts use a low-profile 2-inch perforated waistband with a flat drawcord. This design stays put without digging in, but the waistband is not adjustable beyond the drawcord. If your waist and hip measurements fall into different size categories, choose the size that matches your hip measurement and rely on the drawcord to snug the waist.
How to choose your size in the AeroPro 3 Split Shorts
- Measure your hip at the widest point: Stand with feet together and wrap a tape measure around the fullest part of your hips and butt. This is the primary measurement for these shorts.
- Compare to the size chart's hip range: If your hip measurement falls in the middle of a size range, choose that size. If you are at the top end of a range, consider sizing up for a looser fit through the leg opening. The 3-inch inseam and half-side split mean less fabric; going up one size gives more coverage without affecting waist hold.
- Check your natural waist measurement: Measure around your natural waist (the narrowest part). The 2-inch waistband sits at or just below this point. If your waist is one size smaller than your hip, the flat drawcord will handle the difference. Use the drawcord to fine-tune; do not size down for a smaller waist.
- Consider your preferred thigh fit: The 4-way stretch fabric gives, but the 3-inch inseam leaves less room for adjustment. If you prefer a looser feel around the upper thigh or have muscular thighs, choose the larger of your two possible sizes. A size up still stays secure thanks to the drawcord and stretch waistband.
Product details that affect fit
- Women's AeroPro 3" Split Shorts - They're Here: The outer shell is Accelerator Micro Mesh (83% polyester/17% spandex) with 4-way stretch. The stretch allows the shorts to move with you, so a snug fit through the hip and thigh still feels comfortable during high-knee motions.
