Just my 2 Cents----One concern I have with folding the jacket certain ways is that with multiple zipper jackets--for example jackets with Zipped Cuffs---if the jacket is folded too tightly, you can emboss a zipper mark or more realistically, you can nick the leather with the sharp zipper track teeth or the edge of a pull. I have "Blue Taped" zippers before shipping to protect against this. Also, as has been said, plastic bag is a must. Who knows what kind of shipping conditions the jacket will go through..... When possible, I use the USPS Flat Rate Large Box----"GAMEBOARD BOX". They usually don't have them out on the floor with the other Flat Rate Large boxes. You have to ask for them by that name--Gameboard---its similar to a Monopoly box but thicker. I usually pick up a few at a time at the PO or have them send them to me. You can fold the jacket lengthwise and slip it into the box. This WILL NOT work for Aeros and larger, heavier jackets because they are just too thick for the box. But for most medium weight jackets, it works out fine with minimal folding. Fortunately for all of us, creasing takes much more time to take effect than any shipping time frame.
