Maybe I'm just getting old and sentimental but I do wish that breeches were still available.
I had a pair from Tiso which lasted for years and years and were worn the year round. The material was a bit like an armoured softshell. When it was hot gaiters came off and socks could be rolled down to allow cooling. When it was cold an additional thin layer could be worn underneath.
There was amazing freedom of movement. When climbing and you needed to 'thrutch' they stuck like shit to a blanket. Open cargo pockets on the rear held a folded map comfortably and securely.
Since being forced to wear longer trousers I've lost count of the number I've trashed and have never found any with a packet that would take a map so readily.
I have embraced all other developments. Boil in the bag 'waterproofs' were binned as soon as Goretex shells with venting zips appeared. Wooly shirts and jumpers went out the window when fibre pile made its appearance. Step in crampons and the curving of picks and shafts have been grabbed with both hands. So, I'm not hankering for tradition but something I still regard as the ultimate legwear for hillgoing.
My last pair only gave up the ghost long after the point at which wearing them attracted sniggers and I just long for the day when someone re-invents the wheel.
