A set of leathers!

Just tried my leathers on and they are a bit on the snug side. And by 'a bit' what I actually mean is I can't zip them all the way up and/or bend my arms anymore! Put on a bit too much timber recently.

So, a massive favour to ask but I need to borrow/buy a set of leathers. Pref one piece but a 2 piece would suffice if it they were track day worthy. (Doing oulton park next week)
I'm about 5'9 14st of a stocky kind of build or in numbers that would be a 44in chest and 34in waist 'ish'.

If anyone could help me out it would be much appreciated :-)

Thanks for looking,

Matt
