Size Guide

Sizing

Jerryco uses UK Women's sizing unless otherwise stated. Our Size 4 is designed to fit young riders aged 10+ and is a great starting point for juniors transitioning into adult sizing.

Our pieces are tailored from technical, high-stretch performance fabrics, making them flattering on all body shapes and sizes, and adaptable to both petite and tall lengths.

Riding Leggings

Jerryco garments are cut true to size, and the innovative 4-way stretch performance fabric creates a sleek, sculpted fit that adapts beautifully to your shape. If you are between sizes, we recommend sizing down for the most flattering silhouette.  The 4-way stretch fabric stretches lengthways too, so they are perfect for every leg length, petite, regular and tall. 

Breeches

Equestrian breeches are tailored to have an ankle length fit to prevent bulk under riding boots. Jerryco breeches are true to size, and the technical 4-way stretch performance fabric creates a sleek, sculpted fit that adapts beautifully to your shape. If you are between sizes we recommend sizing down for the most flattering silhouette. The 4-way stretch fabric stretches lengthways too, so they are perfect for every leg length, petite, regular and tall. 

Young Riders / Teens

We have introduced many of our ranges in young rider / teen sizes. Please refer to our size guide table as we recognise children and teens grow at different rates.  If your child is in-between sizes or prefers a larger fit, you may wish to size up.

The measurements in the table below are taken from our competition shirt and leggings laid flat.

How to measure

 

1. Chest:

Measure under the arms at the fullest part around the chest.

2. Waist:

Most of our garments are designed to be high-waisted for sports performance comfort, therefore measure the narrowest part of the waistline.

3. Inside leg:

Equestrian riding leggings and breeches are designed to sit on/above the ankle to avoid chaffing under riding boots, therefore measure from the top of the inside leg to above the ankle bone.

Helite Airbag Sizing

Helite airbag vests and accessories use their own sizing system to ensure optimal safety and fit. Sizes are based on your height and chest measurements, with options for standard and tall fits. Please refer to the Helite-specific size chart and measure carefully, as proper fit is essential for the airbag to deploy correctly and provide maximum protection. Our Helite Cannister sizes (50cc, 60cc, 85cc) correspond to specific vest sizes, so always check compatibility when ordering replacement canisters.
