The short version
- Check compatibility before buying
- Prefer simple, durable fittings
- Do not obstruct lights or moving parts
- Inspect after the first few rides
Waterproofing, ventilation and fit
A shell needs to cover the rider in the riding position without pulling across the shoulders or exposing the lower back. Check sleeve length while reaching the bars and make sure the hood, collar and cuffs do not restrict vision or control movement.
Waterproof fabrics still have limits when effort is high. Front zips, vents and adjustable cuffs can make moisture easier to manage than choosing by a headline waterproof rating alone.
Visibility is a complete-system check
Colour and reflective trim can help a rider stand out in some conditions, but they do not replace correctly aimed lights, observation or road position. Check that a backpack does not cover the jacket's main reflective area or the bicycle's rear light.
Wash and dry the jacket as directed by its maker; fabric softener and inappropriate heat can harm some waterproof or water-repellent finishes.
