In reply to WILLS: I work for Alpkit - I usually post under the username Alpjay but it doesn't seem to be working currently.
The Alpkit jeans were a good investment and a lot of the staff here continue to wear theirs, for all the reasons you have mentioned above. Unfortunately due to the factory having financial problems and the Jeans we did have coming with the wrong size labels and in some cases an odd size we have chosen not to continue selling them in this style.
We however have not ruled out producing more Jeans waterproof or not, a large amount of product development is underway with a large number of new products in the future, similar to other outdoor manufacturers, we are slightly smaller than most though!
For everyone who owns a pair of the Jeanius Jeans, even after a good few years personal use my Jeans have retained some waterproofing. However the majority has worn away, the jeans do dry a lot quicker than any other jeans I have and are a lot more comfy.
I have a pair or two I have re-proofed, the first I haven't worn as much and with a quick wash and a short spin in the tumbledryer, followed by ironing the waterproofing comes back. The second pair which I have used a lot more I have put in the wash with 'Nikwax' Waterproofing wash, and after a few uses I've used the waterproof spray. This has kept them as good as they were before, but still not as good as a brand new set of waterproof trousers.
Hope this has helped and cleared up a few things - any more questions don't hesitate to post on here or drop us an e-mail - support@alpkit.com
