My laksen trousers lasted all but 5 years,@ £80 in the CLA,a superb buy truly 100%waterproof and breathable but i just cant remeber the exact name,i think they're discontinued,sadly.
I used them throughout the year and were my only stalking trousers until I ripped the front on a barb wire.
I'm going to go for the Laksen sika next @ £65ish.
I've also got a pair of Bob Parrat Rexmor trousers @£40,again very waterproof.
Deerhunter ram,@ £40,again 100% waterproof but a bit warm,had them shooting geese in the worst possibble weather the other day and i was bone dry.
