I have a Karrimoor Paclite Gore jacket ( in Red) prob 15+ yo, worn it prob 10-15 times in that time, If its lagging it down, (or forcast) I just don't go out. I also have a , prob 24 yo Parrot windproof/shower proof smock/kagoule,that I love to bits. A few years ago I got caught out ,started out on the Dorset coast 200k in the Parrot, and it absolutely fell out of the sky, stopped at control at Weymouth waiting or it to stop, and got the shivers, putting on the Paclite (much too late) didn't warm me up for prob 10 miles .lesson learned.
I think the Paclite was c. £95 back then, and that was a lot of money, washed it prob 3 times, then ironed the outer, to put back the sheen. never smelt, I now keep it on top of the saddle bag, in a nylon sack, for 'emergencies'
BUT if I go away for a winter weekend, of hostelling and ruff stuff, I always take/wear my ex - German army gortex jacket, with hood.I cut off the internal pockets, sewed up the pocket openings, and used the pocket inners to extend the arms some 5" past the velcro cuffs, to facilitate longer arms when cycling. It has saved my bacon many times, a complete deluge on t'moors near Pinkery YHA, and a complete white out, on t'moors, near te now defunct Crewkern ? YHA, in Somerset. Is been around has that coat. I use a bungee around my waist, and 'hooch' it up for cycliing ( jacket length ) then when a mechanical forces a stop, I let it down again. Only cost £30.
