I bought this waterproof coat and backpack, seperately, over 10 years ago and wow, they have been exactly what this sub looks for. I've used and abused both.
I actually didn't realise they are both from the same brand. I had this realisation that this coat and bag are my most used and lasting items. When I went to post this I realised they were the same brand!
The backpack has survived use on every form of transport you can imagine, being thrown around on the floor and carrying way more weight / size than you could expect it to.
I live in England so the jacket has survived a lot of rain but also, being folded / scrunched up in my backpack in case it rains, which is very often!
Best of all, last year the velcro on one of the cuff straps came off and found out that Berghaus has a repair service (https://www.berghaus.com/repairs.list). I paid for the postage to them (around Β£2) and two weeks later, they sent it back repaired and ready to go for many years more.
I see this every week when I drive to the office. Most of the route is 20mph and single lane. I go at the speed limit and every 2/3 weeks one will overtake me. I'll then see them at the next light, then there next one, then the roundabout, etc for the next 30 minutes. I'll usually then go past them as theres one junction with 2 lanes and they always seem to go in the "fast" lane so they end up behind me when it goes down to one. Makes me so happy everytime!
Sometimes you see it when walking even in a black traffic spot - you'll get to the lights before the cars you've passed sitting there.
Im doing to build my fitness up to cycle the route and think it'll take roughly the same time.
Unfortunately the route is really difficult and long on public transport - it's easy to get into central and back but trying to go across the edge to the other side was never designed for
