G Form Jerseys

Fabric Tech & Weather Performance

The compression fabrics G Form use are moisture-wicking and built to move sweat away from your skin fast - useful on the kind of long, sweaty climbs you get before any rewarding descent in the Peak District or the Brecon Beacons. Ventilated mesh panels are placed strategically across the back and underarm zones, where heat builds quickest, so the jersey doesn't turn into a sauna during slower, grinding efforts. The breathable mesh does real work when air movement is low and humidity is high, which describes a lot of UK summer riding.

Durability is worth flagging here. The compression fabric is tighter-woven than a standard trail jersey, which means it handles contact with abrasive mud and trail grit better than lighter performance fabrics. The SmartFlex™ pads themselves are embedded within the jersey structure, so there's no movement or bunching of the protection over time - they stay put wash after wash. That matters when you're relying on the pads being exactly over the right zones if things go wrong.

Understanding the G Form Fit & Range

Fit is the thing most riders get wrong with padded jerseys, and with G Form it's straightforward once you understand the logic. The compression fit isn't just for aesthetics - it's what keeps the SmartFlex™ pads anchored over your shoulders, ribs, and sternum. If those pads drift during a crash, you lose the protection you paid for. So the fit needs to be snug. Not uncomfortably tight, but noticeably closer than a relaxed trail jersey.

If you're between sizes, size up. That's consistent advice from everyone who's spent time with the range. Going a size up keeps the pads in position without the jersey feeling restrictive across the chest or shoulders during movement. Riders with a broader upper body should factor this in from the start rather than defaulting to their usual size.

The Pro-X shirt is the key model for riders wanting a protective base layer they can build a kit around. It's designed to sit cleanly under outer layers - a waterproof jacket, a wind shell, or a heavier winter layer - without adding noticeable thickness. If you want something with a slightly more relaxed outer-layer feel, G Form also offers trail jerseys with a less compressive profile, though the protection integration is less comprehensive than the Pro-X line. For riders who want to match the jersey to full-system protection, pairing it with G Form body armour or G Form MTB baggy shorts gives you consistent SmartFlex coverage across more zones without stacking incompatible fit systems.

Compare this approach to what you get from Alpinestars jerseys or 100% jerseys - both solid options, but neither integrates impact pads at this level of coverage as standard. If protection is the priority rather than a bonus feature, G Form's range has a clearer focus.

Layering & Care for UK Riding

One of the practical strengths of the Pro-X shirt is how cleanly it sits under other layers. On a typical UK autumn or winter ride, you might start in just the jersey, add a wind shell for the exposed ridge section, then shed it again on the descent. The low-profile padding doesn't create pressure points under a jacket, and the compression fit means there's no excess fabric to bunch up around the waist or under the arms. It's the kind of thing you only notice when you've worn layering systems that don't work as neatly.

For summer riding, the jersey works as a standalone piece. The UPF 50+ fabric and ventilated mesh panels are doing enough thermal work that most riders won't need an additional base layer beneath it. On longer days in the saddle - the sort of all-day riding you get at trail centres like Glentress or Ae Forest - the moisture management keeps things comfortable without feeling clammy after the first hour.

Washing is simple but the drying step is where riders sometimes go wrong. Machine wash on a cold, gentle cycle - that's fine. But tumble drying will damage the SmartFlex™ pads over time, degrading the impact-absorbing properties you're relying on. Air dry only, ideally flat or on a hanger, away from direct heat. The jersey dries reasonably quickly given the compression fabric weight, so it's not a major inconvenience. If you're heading out on back-to-back riding days, picking up a second jersey from the range is a sensible move rather than rushing the drying process. Check out G Form gloves while you're sorting the rest of your kit - same SmartFlex approach, same care rules.

For riders considering alternatives with a less structured protection system, Dakine jerseys offer solid build quality and a more relaxed fit profile, which suits riders who prioritise freedom of movement over integrated padding. It's a genuine trade-off - G Form's compression approach is more purposeful for protection, Dakine's is more casual in feel. Neither is wrong; it depends what you're asking of the jersey.

Frequently Asked Questions

Do G-Form padded jerseys fit true to size?

The compression fit runs close by design - the pads need to stay over your shoulders, ribs, and sternum to work properly. If you're between sizes or prefer a bit more room, go a size up rather than down.

Can you wash G-Form jerseys in the washing machine?

Yes - cold water, gentle cycle, and you're fine. The critical bit is the drying: always air dry. Tumble drying breaks down the SmartFlex pads over time and you'll lose the protection they're there to provide.

Are G-Form jerseys breathable enough for summer riding?

Yes. The moisture-wicking compression fabric and ventilated mesh panels manage heat well enough for humid UK summer climbing. They're not as airy as an open-knit trail jersey, but the trade-off is integrated protection that a standard jersey can't offer.
