Sorry, no need of this, its the swing from ground to shoulder that matters.
What I personally would like designed is -
Gaiters that just snap on, secured just under the knee and around the ankle. Messing about with zips, velcro and lace lugs is a chore!
After washing bits of clothing I would like a washing line that snaps onto the back of my rucksack. It needs to fold up, be lightweight and offers an air gap for better drying time between my wet clothing and the fabric of the rucksack.
I also wear a rain skirt, to work better it needs a cleverer way of securing the vertical overlap of the fabric. When I take a large step, say across a boulder or for example when its raining and windy, the 'seal' that keeps the wet out can get broken and it needs a better way of coming together again. Not velcro please, magnets perhaps?
Why do trouser firms not offer a 'slap on' piece of waterproof fabric to fit on the inside of each leg. What I would like is to get to a pub, whip off the muddy patch and walk in with clean trousers. When I resume my hike I just want to 'slap' them on again and clean them when I stop in the evening.
Over to you!
