I just got a brand new leather coat and it is quite stiff. Is there a good leather conditioner or rub or something than I can put on it to soften if up to help speed up the break-in and help it conform to me?
Got a new Vanson motorcycle jacket as a late Christmas present from the fiancee's parents. It's all handmade in the USA, so it wasn't cheap, but GODD*MN, the quality is second-to-none. Nice thick leather that can take a fall and slide, top-quality stitching too. Of course, you want something that won't wear through or fall apart in a slide on asphalt. This thing is such high quality that I could easily see it being passed onto my Grand-kids, as long as it was taken care of.
However, it's D*MN stiff, especially in the arms, so I'm trying to figure out how to soften it up. I fully intend to wear it, and often, but being July in Louisiana, a (primarily) black leather jacket isn't the best summer wear, unless I'm on the bike with air moving over me. I am surprised though, the liner isn't bulky, so it feels very light and "breathes" well for a leather jacket.

I LOVE this jacket. Most people don't "get it", especially in the Army, but those that are hip to it, LOVE it.
