Gonso Bib Shorts
Gonso bib shorts are built around a simple idea: your chamois should fit how you actually ride, not how a marketing department thinks you ride. The standout feature is the Sitivo saddle pad system, which matches pad density and geometry to your specific riding posture - aggressive sportive, compact road, or upright touring - so the support lands exactly where your sit bones make contact. That's a genuinely different approach from most brands, who offer one pad shape and call it done.
Beyond the pad, you're getting moisture-wicking Econyl recycled fabric, breathable mesh bib straps that don't trap heat across your chest, and silicone leg grippers that hold position without cutting in after three hours in the saddle. For UK riding, where a muggy summer climb can soak you before the first café stop, that combination of breathability and quick-drying stretch fabric matters more than it sounds.
Fit-wise, Gonso runs true to size - a relief if you've been burned by overly compressive Italian sizing before. These are endurance bibs at heart. If you want all-day comfort on a club run, a sportive, or a multi-day tour rather than a skin-tight race replica, this is the range worth looking at.

Fabric Tech & Weather Performance
Gonso builds many of its bib shorts using Econyl recycled fabric - a regenerated nylon yarn made from reclaimed fishing nets and industrial plastic waste. It's not just an environmental tick-box: Econyl delivers genuine four-way stretch, holds its shape wash after wash, and resists the fabric fatigue that cheaper lycra shows after a season of hard use. The compression is graduated rather than aggressive, so it supports muscle groups without leaving you feeling like you've been vacuum-packed.
Moisture-wicking performance is where Gonso quietly earns its reputation. The fabric pulls sweat away from the skin efficiently, which keeps you comfortable on the kind of muggy, close August climbs you get in the Peak District or the South Downs - where the air feels thick and your legs still feel fresh but your kit absolutely doesn't. Crucially, the material dries quickly. Get caught by a summer shower mid-ride and you won't spend the last 30 miles in cold, heavy fabric that chafes with every pedal stroke.
The mesh bib straps run in the same direction as the technical fabric story. Wide and highly breathable, they distribute shoulder pressure evenly and allow air to circulate across your chest and back - something you notice on longer efforts when solid straps start to feel like a warm compress. Compared to the structured bib panels you'll find on Castelli bib shorts, Gonso's approach is more relaxed and ventilated, which suits endurance pacing over race-day intensity.
Understanding the Gonso Fit & Range
The Sitivo chamois system is the detail that separates Gonso from most of the market. Rather than splitting pads by gender alone, Gonso offers three distinct variants colour-coded by riding position. Red is for an aggressive, forward-rotated posture - think sportive riders or those spending long hours in the drops. Green suits a compact road position, the default for most club cyclists. Blue is designed for a more upright touring stance, where the weight distribution across the saddle shifts noticeably rearward. Pick the wrong one and you'll have padding in the wrong place; pick the right one and long days simply feel less punishing.
The overall fit profile is generously cut by cycling standards. Gonso sizing tends to be accurate to your body measurements rather than aspirationally small, which means if you're between sizes you don't need to automatically default to sizing up. The leg panels offer a close but not restrictive fit, and the silicone leg grippers are wide enough to stay put without marking your skin - a small detail that becomes very relevant by hour four. If you're used to brands like Endura bib shorts or Gore Bike Wear bib shorts, expect Gonso to feel slightly roomier in the seat and thigh without sacrificing the aerodynamic leg fit.

Layering & Care for UK Riding
UK riding seasons don't operate in neat categories. A May morning in the Chilterns can start at six degrees and hit eighteen by eleven, which means your bibs need to work alongside other layers rather than in isolation. Gonso's bib shorts pair well with knee warmers for those chilly early starts - the silicone gripper on the bib leg sits cleanly under a knee warmer cuff without bunching or slipping. As the ride warms up and you peel the warmers off at a junction, the bibs hold their shape rather than riding up or shifting out of position.
For moisture management across the whole kit, pairing Gonso bibs with a Gonso jersey makes practical sense - the fabrics are developed to work together, with compatible wicking rates that keep sweat moving away from your body rather than pooling at the waistband. It's the kind of thing that only becomes obvious when you mix and match poorly and end up with a damp band of fabric sitting against your lower back for 40 miles.
Care is straightforward but worth doing properly. Wash the bibs inside out at 30°C with a mild, non-biological detergent. Fabric softener is the enemy of chamois foam - it degrades the breathable membrane and compresses the padding structure over time, so skip it entirely. Air dry rather than tumble drying; the heat damages bib strap elasticity faster than anything else, and once that snap goes the straps hang loose and the whole fit shifts. Done right, a quality pair of Gonso Gonso cycling bib shorts will hold their performance characteristics through several seasons of regular riding.
Gonso Bib Shorts FAQs
How do Gonso bib shorts fit compared to other brands?
Gonso runs true to size and cuts its bibs with a slightly more generous seat and thigh compared to typical Italian race brands. Most riders find their standard size works well for endurance comfort. If you specifically want a highly compressive race fit, you could size down, but for long-day riding the standard sizing is the better call.
What is the Gonso Sitivo chamois system?
The Sitivo system matches the chamois pad to your actual riding position rather than just your body type. Red suits an aggressive, forward-leaning sportive posture; Green fits a compact road position; Blue is designed for an upright touring stance. Choosing the right colour means the padding supports your sit bones where you genuinely apply pressure.
How should I wash my Gonso bib shorts to protect the pad?
Turn them inside out and wash at 30°C with a mild non-bio detergent. Never use fabric softener - it breaks down the chamois foam's breathability over time. Skip the tumble dryer too; air dry away from direct heat to preserve the bib strap elasticity and keep the pad structure intact wash after wash.
