Still cool enough in morning/evening commute to be wearing my gortex-textile jacket and pants.

When it gets proper hot i swap to a vented leather jacket and Draggin Jeans. I tried a mesh air-flow jacket thing, but it was too cold, and you dont get that sweaty wearing a vented jacket.

Gloves i use Alpinestars 365. They're ok for most weather, but probably too hot if it gets over 30C.

I use Kevlar jeans all year round!
If it gets seriously hot, I have a Draggin Jeans Ultra light jacket, which lets air flow through it, which is great.....though it has to be seriously hot before you can wear it, or you'll freeze!

Hein Gerricke "Airstream" suit, feels like a t-shirt and shorts when you are moving.

I like my Hood jeans too

Another vote for Hood jeans, also worn all year round, I guess the advantage of some scooter weather protection meaning even in winter I just need thermals underneath and occasionally waterproofs over the top.

I also tend to wear the Joe Rocket mesh summer jacket nearly all-year round, just adding hi-viz bomber over the top when cold. SWMBO kindly fitted the Hood jeans with the zip half from the Joe Rocket so they zip together, also works with my Winter jacket too, as that's also Joe Rocket.

Thanks to all for the comments and suggestions. I went to J&S in Doncaster and me and the Mrs got sorted out. Combat trousers fitted better than the jeans. Kevlar reinforced with Knee armour. A mesh type jacket with waterproof cover included. A windproof inner for under the jacket if it comes over chilly. And lastly some summer gloves. Cost a fortune but we are cooler and hopefuly safer.

Extremely good service by the way - highly reccomend the place.
