learning the hard way again that carrying too much gear in the ruck is bad on the knees... and my knees aren't getting younger... i figure between advil and staying hydrated and compression knee sleeves and trekking poles and lightening the ruck i can perhaps backpack hunt until 70... 7 years away... local winds have been fierce lately when on the trail, which brings me to the subject title

one piece of gear i need to figure out is an upper outer layer to stop the wind... something supple and quiet. doesn't have to offer insulation...just block the wind from cutting thru me and turning the perspiration into icicles. easy to stuff into the ruck. Something I can wear as the outer garment with just a thin polypro baselayer underneath when humping the hills... something that won't get torn up by backpack straps... moisture wicking... when i stop, the idea is to change out to dry baselayers and then put the wind garment outer on again...

recommendations appreciated.
