    How To Pick the Correct Size Cycology Jersey

Everybody wants their cycling jersey to fit well and feel good! We offer a variety of different cuts that range from the most form-fitting to the loosest fit, allowing you to choose the style that makes you comfortable.

Below we explain the differences in our jersey fits and give you detailed garment measurements so you can compare to a favourite fitting jersey you may have. There is no standard sizing fit between cycling brands so please take the time to use a measuring tape, get an idea of what you need, then consider these fits before you make your size decision.

How it Works

Knowing how a jersey fits can help with selecting the right size. We've designed three different fits.

1.Performance Fit -close fitting using performance stretch fabrics that hug the body.

2.Relaxed Fit - a looser fit that sits slightly away from the body.

3.Race Fit – tight aerodynamic fit, sits extremely close to the body.

    Our most popular jersey style is the performance fit. This is best described as a close fitting garment. If you prefer a looser fit, then a Relaxed Fit jersey is the way to go. The Race Fit is for the serious rider who wants to be as aerodynamic as possible and have no "flappy" bits of fabric. It is meant to be worn tight on the body.

    How to know your size

    Here is a great tip - lay your favourite fitting cycling jersey flat, then measure the crucial areas:

    • across the chest just under the armhole
    • the zipper length for the front
    • the back length from under the collar to the bottom of the hem.

    Compare these to our size guides below for the garments you are interested in! You can then duplicate the magic of your favourite jersey.

    Remember we have 3 road jersey fits.

    PERFORMANCE FIT

    These are made with superb thermal regulating, very fine high-stretch fabrics. They're light-as-air, meant to be worn close to the body. Beautifully cut and supremely comfortable to wear, designed to fit firm so they breathe and move with the body.

    These have:

    • raglan sleeves
    • a collar
    • YKK zipper
    • grippers on sleeves
    • the front panel has laser cut gripper
    • the sides and back panel have silicone gripper elastic.

    In our men’s jersey, 4 way stretch fabric is used on the core body of the jersey whilst 2 way stretch fabric is used on the back panel to minimise sagging.

    There is a zippered safety pocket on the rear with 3 more pockets. We added 2 reflective tapes on the back pockets for safety.

    This is a close fitting jersey. If you are in doubt on sizing or prefer a slightly looser fit, it may be worth sizing up. We get more returns due to customers finding the jerseys smaller than they expect so that may be worth considering in your size selection. We do however have a very useful sizing tool on each product page and if you update this to your actual body dimensions the recommended fit should prove very helpful.

    RELAXED FIT

    This jersey style is for those people who prefer a looser fitting garment without the high stretch body fit of our current Performance range. It is designed with a more generous cut, made from 2 way stretch fabric with loose cuffs on the sleeves for full freedom of movement. The relaxed fit is more like a comfy tee, with a zipper. NOT firm on the body. Very tough fabric and 3 rear pockets, plus a zippered safety pocket. This cut is often referred to as a Club Fit.

    RACE FIT

    Designed for speed and efficiency. Lightweight, smooth, air permeable fabrics wick sweat away fast. It has an aerodynamic cut with longer length inset sleeves with a laser cut finish (no sewn-on gripper). It is meant to be worn skin tight and is a small fit. The best quality YKK zipper and a low cut race neckline. The 3 rear pockets are cut flat & close to the body for another aerodynamic advantage with bonded tape at the top of the pockets to provide support for bare necessities. Silicon gripper on side and rear panels, the front panel has bonded elastic for a smooth and seamless look.

    Race fit in the wild!

    Two other options to consider for those not into road racing of KOM is a MTB Jersey or our recently released gravel shirt - this is great for a ride where you are going to stop in cafes (or pubs!) and want a more relaxed day on the bike. These different categories of garments are made with beautiful sweat wicking fabrics so they offer excellent performance characteristics but with a more relaxed and casual feel.

    What is a gravel bike and why is gravel riding becoming so popular?

    Many of the bikes shops we talk to report that gravel bikes are hugely more popular than road bikes these days and this interest keeps on growing.The key reason, as road bikes have progressed to be lighter, stiffer and more aero, they have become less practical for most roads and almost all gravel/dirt.
