MTB Jersey Buying Guide

DH vs Trail vs XC Jerseys

Downhill jerseys are the loosest — designed to fit over body armour with mesh panels for airflow. They're typically long-sleeve with minimal features beyond a basic crew neck. Trail jerseys sit in the middle: semi-fitted, often with a dropped rear hem and zip neck for ventilation on climbs. XC jerseys are tighter and more technical, similar to road jerseys but with slightly more relaxed cuts and pockets positioned differently for pack-wearing riders.

Fabric and Construction

Most MTB jerseys use polyester mesh or blends for moisture wicking. Weight matters: sub-150g/m² fabrics breathe well for summer, while 200g/m²+ fabrics offer warmth for autumn riding. Merino wool blends (Mons Royale, Rapha) regulate temperature naturally and resist odour but cost more and dry slower. Flat-lock seams prevent chafing under pack straps. Reinforced elbows on trail jerseys add crash durability.

Fit Considerations

MTB jersey sizing is less standardised than road. Fox and Troy Lee run large — most riders size down one from their t-shirt size. Endura and 100% run more true. The jersey needs to be long enough in the torso that it doesn't ride up when you're in an attack position, but not so long it bunches at the waist. If you wear a hydration pack, check the jersey doesn't bunch under the straps — mesh-back jerseys specifically address this.

Long Sleeve vs Short Sleeve

Long sleeve is the default for UK trail riding. It protects against brambles, nettles, and UV, and adds a layer of crash protection. Short sleeve works for peak summer when temperatures and pace are high. Some riders run long-sleeve year-round and adjust layering underneath. Convertible zip-off sleeves exist but add bulk and rarely fit well.

Features Worth Having

A zip neck lets you dump heat on climbs — half-zip or quarter-zip both work. Goggle wipe panels on the hem or sleeve are genuinely useful for wiping lenses mid-ride. Some trail jerseys include a small rear pocket for a phone or gel, though most MTB riders carry a pack. Reflective elements help if you ride on roads to reach trails.

Buying Used Jerseys

Jerseys are one of the safest used kit purchases — they're essentially just shirts. Check for pulls or holes from crashes, and inspect the collar and cuffs for stretched-out elastic. Polyester jerseys wash well and last years if they haven't been tumble-dried excessively. Fading from UV is cosmetic only. Merino jerseys may have developed thin spots or small holes — hold them up to light to check.
