I would go for the mouton.As we know, the McCoy's N-1 is expensive. And then they make one that is even more expensive -- the SPL version, with mouton collar, different zipper, and heavier exterior. Money no object, which would you prefer?

This isn't the first issue of the SPL. SPL first introduced Khaki version in 2014, Navy in 2016. Back then the SPL was only available at RM own stores in Japan yet they sold out real fast. One of the best selling limited edition.As we know, the McCoy's N-1 is expensive.

It isn't just frills, it is actually warmer. I have no need for that though cos where I live, I don't even get to wear my normal N-1 repros that much.resist the urge to add frills to a utilitarian object..........simple is better and original is better.
The mouton collar is overkill for me but that is what makes it is warmer than the standard one.^ That was actually my concern. The standard N-1 is already so warm, I can't imagine how warm the heavier SPL would be.
Then there's the mouton -- really nice, warm, and comfortable, but is it over-the-top for the utilitarian N-1?
