I have a Belstaff Trialmaster that is one of my favourite jackets for general city-wide or shorter rides as it is, unsurprisingly, perfect for British weather. 
Used it in the rain to the office the other day and I ended up having two massive wet stains under my armpits and it made it look like I ran 10 miles uphill.
Don't remember having water ingress in the jacket before, this is on both arms at the same time, I don't think it's through the breather holes.
Is there any know seams failure on these jackets? Or is it just time for a re-wax?
I thought the wax was there mostly for the looks these days, and the waterproofing is in a new textile they use?
Thanks
