Knox sizing & how to measure

Measure yourself once, then match it to Knox's chart on any product page. Here is exactly what to measure for each kind of Knox gear.

Bust
Measure around the fullest part of the bust, keeping the tape parallel to the ground.
Waist
Measure around your natural waistline, around the top of the hip bones, inline with the navel while keeping the measuring tape parallel to the ground.
Hips
Measure the circumference, from pelvic bone to pelvic bone, at the widest part of your hips below the waist.
Arm (Neck to Wrist)
Standing up straight with your arms at your sides, measure from the base of your neck at the center of your spine, along the top of your shoulder and down to your wrist bone, along the outside of the arm.

What riders praise

Compressive, second-skin fit that feels secure on the bike
Body and sleeve length praised by taller riders (5'9" rode comfortably in a medium)
Works as a warm-weather layer and can be worn under a hoodie in the cold
Pockets and feminine silhouette are recurring highlights
Darts and seams designed for a genuine women's silhouette, flattering for hourglass builds
Armor placement feels better-positioned than typical riding jackets

Watch-outs

All six reviewers rated fit as slightly small, measure carefully and consider sizing up
Very compressive material can be difficult to put on, especially with armor installed
Sleeve cut is very slim, riders with muscular arms or broader upper bodies will find movement restricted
Sizing is slim overall; most riders rate Small or Slightly Small
Sleeve armor makes layering a regular jacket over the top difficult
Cut assumes a tall build with large hips and thighs and a narrow waist, a very specific body proportion that does not match most riders
