Had a pair of the natural colored ones, lasted my 10 years and were extremely comfy once broken in, lost one while exploring off the bike and bummed me out...
I'll warn you tho, the black ones are just as tough, but have one downfall... when soaked, they will dye your hands black... and it takes a long time to get to a point they won't do that anymore... like years of riding in the rain....
The yellow ones don't dye your skin so badly...
With that explained, here's a direct and concise method for conditioning new gear... from Aerostich...
Goldstein has a good sense of humor...
"Here is an authentic (albeit nonsensical) way to fairly quickly break in your stiff brand-new Aerostich Darien Jacket, pant or riding suit:
Remove impact armor and all contents of pockets.
Soak jacket in large bucket of muddy water for fifteen minutes to three hours.
While jacket is soaking, dig, or hire someone to dig a hole in the ground large enough to bury the jacket fully.
Wad up the still-wet jacket and bury it in the hole.
Water the dirt covering the jacket liberally, as if the hole contained a plant seedling.
Wait three days, then dig up the jacket and let it air dry.
After drying out, grab the jacket by the shoulder area and whip it hard against the trunk of a large tree five or six times. (This step may also be done when the jacket is wet.)
Replace impact armor and wear the broken-in jacket with pride.
Alternatively, ignore steps 1-8 and just put on your stiff new Aerostich gear and go do some riding"
By the same token, I'll share how I broke my ropers in...
Soaked them in HOT water for 2 hours, pulled them out, stuck them outside in the shade to cool..
Put them on, and rode for six hours... or untill they were dry...
Pulled them off, left them on the seat of my bike overnight when I camped... boiled water for morning coffee, and made coffee in my coffee press, and poured the rest of the water into my empty granola bag, and inserted my gloves till I finished coffee, granola, and did my morning pooparama.. followed by another coffe while my soaked gloves cooled.. donned the gloves and rode another 8 hours, pulled them off and never worried again. Till I lost one.
Ymmv, if you have black gloves, well, I suggest using hand creme and rubber gloves under the ropers for 3 days of rinse and repeat...
Live long and prosper... nanu nanu...
