Mind you reading what they say on Aero Leathers, I would just leave it be, it's part of the breaking in - don't be precious.

Wearing A New Horsehide Jacket
Just wear it, don't be precious with it, don't mollycoddle it, but don't ever hang it up on a hook at the back of the neck.

Otherwise, these jackets like to be treated roughly... but don't leave it on the back of a chair in a pub whatever you do, it'll be gone in a flash in most areas, quicker than you could say "Where's the gardener?"

Treating The Leather
This is even easier. Do nothing, absolutely nothing. Do not oil it, don't treat it with hide food - even ours, this is for old steerhide jackets and dried up old vintage horsehide jackets from the 1930s and 1940s, not for your Aero, well not until maybe 2035.

Ollie...with all new leather...you have to take them to your boudoir EVERY night for 3 weeks straight...and make sweet love to them in a variety of positions... with all the gusto you can muster Sir....

Further..during the midpoint of each week you should wear it out to a dodgy boozer and get yerself into a bar brawl...where you should roll around as much as possible in the most unkempt bits of thee establishment and as much shite on the floor as possible... at the end of this 3 week period...enjoy a concoction of 13 pints of Old Peculiar and long-gone-by-use-by-date oysters....projectile vomit down yourself...and voila....then....just then....you have the start of something good on the jacket front my friend...

Trust me.....I is a leatherizer professionale geez....

Enjoy!

He he...yep...send it over my man... you won't regret it...
