Gonso Jackets

Fabric Tech and Weather Performance: G-TEX and Softshells

The G-TEX membrane is Gonso's in-house waterproof and breathable laminate, used across their hardshell jackets. Think of it as their answer to the well-known names in waterproof membranes - a bonded layer that stops rain penetrating while letting water vapour out, so you don't swap wet-from-rain for wet-from-sweat. Critically, the hardshell models pair G-TEX with fully taped seams, which closes off the stitching lines that lesser jackets let water sneak through. For heavy UK downpours - the kind that roll in off the Bristol Channel with no warning - that combination of high hydrostatic head rating and sealed seams is what keeps you genuinely dry rather than just damp-but-managing.

The softshell side of the range takes a different approach. These jackets use a PFC-free DWR coating that beads light rain and blocks wind effectively, but their real strength is breathability. On a steep, humid climb - the sort you get in the Brecon Beacons in October - a hardshell can turn into a sauna. A well-made softshell moves moisture out fast enough to prevent that clammy chill when you stop at the top. Gonso's softshells are tuned for exactly that: wind resistance and water resistance in a package that doesn't fight you on the way up. The PFC-free DWR is worth noting for riders who care about what goes down the drain after washing - it performs well without the fluorinated chemistry older coatings relied on. One practical point: DWR does deplete over time, and a softshell that's started wetting out rather than beading is usually a jacket that just needs reactivating, not replacing.

For deep winter, selected Gonso models add Primaloft insulation. Primaloft retains warmth even when damp, which is relevant given how quickly a UK winter ride can shift from dry to soaked. It's not the choice for high-output climbing, but for commuting or slower touring miles in single-figure temperatures, the warmth-to-weight ratio is genuinely useful. If you're looking at Endura jackets or Altura jackets in the same category, it's worth comparing how each brand handles that breathability-versus-insulation trade-off - Gonso's touring focus often means they prioritise comfort across a longer day rather than peak aerobic performance.

Understanding the Gonso Fit and Range

Gonso's fit philosophy is the thing most riders notice first - and it's deliberate. Where a lot of cycling outerwear is cut for a rider bent low over drop bars at race pace, Gonso patterns their jackets for a more upright position. That means the drop tail covers your lower back properly, the sleeves sit right when your hands are on the bars without pulling the hem up, and the chest doesn't feel like it's mapping your ribcage. Articulated sleeves are standard across most of the range, so reaching forward doesn't create that bunched, restricted feeling across the shoulders.

The inclusive sizing is a genuine differentiator. Gonso runs broader size options than many European cycling brands and cuts for a wider range of body shapes. If you've previously found cycling jackets either too narrow across the chest or too long in the body, it's worth checking Gonso's size guide carefully - riders often find they can size more accurately here than elsewhere. The touring fit also means the jackets layer realistically; there's room for a thermal mid-layer underneath without the jacket going taut across your back.

The range broadly splits into hardshells for committed all-weather riding, softshells for variable conditions where breathability matters more than absolute waterproofing, and insulated jackets for winter commuting. If you want to strip weight mid-ride on warmer days without losing wind protection entirely, the Gonso gilets are a logical companion - packable, core-focused, and built in the same fit language as the jackets. For full lower-body coverage on the wettest days, Gonso overtrousers are designed to pair with the jacket range without bunching at the waist.

Layering and Care for UK Riding

Getting the layering right makes a bigger difference than most riders expect. Under a Gonso thermal softshell in winter, a moisture-wicking base layer does the heavy lifting - it pulls sweat away from your skin so the jacket isn't dealing with a saturated layer underneath. Pair that with a lightweight Gonso jersey as a mid-layer and you've got a system that handles most of what a UK winter throws at commuters. For touring or longer days, packing a lightweight G-TEX hardshell in a jersey pocket or bar bag means you've got genuine rain cover on demand without committing to it all day.

On washing: use a dedicated technical wash - something like Nikwax Tech Wash - rather than standard detergent, and never use fabric softener. Fabric softener clogs the breathable membrane and degrades the DWR coating faster than almost anything else. That's the jacket ruined quietly over a few washes. Tumble dry on a low heat setting after washing; the warmth reactivates the DWR so water beads again rather than soaking in. If the jacket is still wetting out after that treatment, a DWR re-proofer spray will usually restore performance. Store jackets loosely rather than compressed long-term - repeatedly crushing an insulated or membrane jacket accelerates wear on the loft and laminate. A bit of care here and these jackets last considerably longer than the price point might suggest. For days when you're pairing the jacket with bib tights or softshell trousers, Gonso trousers are cut to the same relaxed touring fit, which keeps the whole outfit consistent rather than mixing cuts that fight each other at the waist.
