So here's what I ended up with,
Spada Enforcer gloves, just the job!
Caberg Justissimo lid, best fit by far even if a little noisy.
RST Paragon III Jacket, perfect fit, very warm and comfortable.
RST paragon trousers, great fit, but why do these companies put the knee armour on the shin??
I looked at getting the RST Paragon gear, but couldn't find a stockist near me. Shame as they look good and got good reviews.
I ended up going to Infinity Motorcycles in Southampton, and looking at their Spada range. I intended to get their Dakar or Adventure kit, but again, nothing to try on. I left with a Spada Forest, which fits perfectly given I'm 6'4" with long arms.
