Just been crunching some mileage records. Although I perceive my Enduroguard kit as "new", in fact it isn't. I bought the suit 31/10/19 with the K13 so its 4.5 years old and I have worn it for almost all of the 35,000 miles I've ridden since on both bikes. The gloves were bought on 28/9/20 and have covered almost all of the 26,500 miles since. I blame Covid for fogging my memory, and I have revised my opinion of "humph that waterproofing didn't last long" to "oh, not so bad".
Offhand I'd say the gloves are the most durable I've ever had. My Hein Gericke touring leathers have lasted much longer than 4.5 years, my trousers are at least 17 years old as I bought them before moving here from Scotland, and my jacket is about 10 years old, but I have hardly worn them since buying the Enduroguard suit and they aren't waterproof. Most of the zips have been replaced but that's it. My claim to fame is that the 17 year old trousers still fit...
Not sure what durability other people are getting but maybe there's a thread worth starting on this?
