Gonso Gilets
Gonso cycling gilets solve one of UK riding's most persistent problems: the morning that starts at six degrees and ends in a sweaty grind up a shadeless climb. That means you need a layer that earns its place on cold descents but disappears quietly into a back pocket when the road tilts upward. Gonso's gilet range does exactly that - windproof protection across the chest, serious breathability through the back, and a packable construction that won't add bulk when you're already carrying a tube, a bar, and your optimism about the weather.
The core idea is simple. Block the wind where it matters most - your chest and core - and let heat out where it builds fastest, through the rear panels. Gonso executes this with lightweight fabrics, DWR-treated front sections, and mesh or perforated backs that prevent the boil-in-the-bag feeling you get from a full jacket on a long drag. Reflective detailing keeps you visible as the light drops on those autumn afternoon rides, and two-way zippers let you reach jersey pockets without unzipping your entire top half. Fit is measured and practical, not aggressively race-cut. If you're after a gilet that works with real-world layering rather than against it, Gonso is worth a close look.

Fabric Tech and Weather Performance
Gonso's dual-fabric approach is what separates a genuinely useful gilet from one that just looks the part on the peg. The front panels use a windproof construction - often built around a Windtex membrane - that cuts windchill effectively on exposed stretches, whether that's a moorland drag in the Peaks or a fast A-road descent after a café stop. You won't feel that creeping cold through the chest that turns a good ride sour.
The DWR coating on the outer fabric handles road spray and passing showers well enough to keep you comfortable when the rain is light and brief. It's not a substitute for a waterproof jacket on a properly wet day, but for the typical April shower or October drizzle that UK riders know well, it buys you enough time to make a decision. Worth knowing: DWR performance degrades over time, but it can be restored - more on that below.
The rear of the gilet is where clever design earns its keep. Breathable mesh back panels dump heat rapidly during high-effort climbs, so you're not cooking from the inside out the moment the road goes up. Think of it as the gilet breathing for you when you're working hardest. This rear ventilation is what makes the layering system genuinely functional rather than a compromise - the windproof front stays locked on, and excess heat simply exits through the back rather than building into discomfort. Lightweight ripstop fabrics used across the range add durability without meaningful weight penalty, which matters when the gilet needs to survive being stuffed in and out of a jersey pocket repeatedly across a season.
Understanding the Gonso Fit and Range
Gonso sits in a different place on the fit spectrum compared to, say, a razor-cut Italian race brand. The fit is purposeful and performance-oriented, but it's shaped around riders who want to actually wear their kit in varying conditions rather than optimise purely for aerodynamics. That's a sensible call for UK riding, where layers change constantly and a gilet that only works over a base layer is limited in practice.
A well-fitted gilet should sit flush against your chest and shoulders - any excess fabric here becomes a wind sail and costs you warmth and efficiency in equal measure. At the same time, it needs enough room across the back and shoulders to allow a free pedalling position on the drops without riding up. Gonso's cut generally accommodates this well, offering a comfortable range of movement without the bagginess that catches cold air.
On sizing: if you're planning to wear your gilet over a heavier jersey or a thermal mid-layer through late autumn, consider going up a size. It's a gilet, not a base layer - a small amount of room for extra fabric underneath isn't a fit problem, it's sensible kit management. If you're primarily using it over a lightweight summer jersey on chilly spring mornings, your usual size will suit. Check the specific model's sizing notes on the product page, as cut can vary slightly across the range. Riders who find Löffler gilets on the snug side often find Gonso's fit more accommodating.
Layering and Care for UK Riding
The gilet works hardest as part of a considered layering system rather than a standalone fix. For spring and autumn riding - the seasons that genuinely test your kit choices - pair it with Gonso jerseys and a set of arm warmers. That combination covers most conditions from about six degrees upward without overloading your pockets or your luggage. When the temperature drops further, slot the gilet over a thermal mid-layer and under a softshell for the kind of modular system that lets you adapt without stopping the ride. Pairing it with one of the Gonso jackets gives you a genuinely flexible wardrobe for the colder months.
Packability is the feature that makes the gilet worth carrying even on rides where you're not sure you'll need it. Most models in the Gonso range compress down small enough to fit into a standard jersey back pocket alongside your other essentials. Don't leave it behind because you think you won't need it - British weather has strong opinions on that kind of optimism.
On washing: treat your gilet carefully and it'll perform well for seasons rather than months. Wash at 30°C using a technical detergent or a non-biological alternative. Avoid fabric softener entirely - it clogs the breathable rear mesh and degrades the DWR coating on the front panels faster than anything else you can do. Air dry where possible. If the DWR is beading less effectively and water is starting to wet out the fabric rather than rolling off, a low-temperature tumble dry or a specific DWR re-proofer treatment will usually restore performance. It's a small maintenance habit that keeps the gilet working as it should. For comparison, riders who've run Altura gilets and Endura gilets through the same care routine report the same improvements to DWR longevity.
Gonso Gilets FAQs
Are Gonso gilets true to size?
Generally, yes - Gonso runs a comfort-oriented fit that's fairly consistent with standard European sizing. If you're planning to layer heavily underneath, such as over a thick winter jersey, go up a size. For use over a lightweight summer jersey on cool mornings, your usual size will be right.
Should a cycling gilet be tight?
It should sit flush across the chest and shoulders to stop wind flap, which both chills you and wastes energy. It shouldn't be so snug that breathing is restricted or layering becomes impossible. Think fitted, not compressive - there's a clear difference between a clean aerodynamic line and something that digs in on a three-hour ride.
How do you wash a windproof cycling gilet?
Wash at 30°C with a technical or non-biological detergent. No fabric softener - it blocks the breathable rear mesh and strips the DWR coating from the front panels. Air dry if you can. If the DWR has lost its effectiveness, a low-heat tumble dry or a dedicated re-proofer spray will usually bring it back.
