Go on then, since you're so kindly offering to answer more of my questions...I know your two jackets are totally different sizes, but what are the pit-to-pit and waist measurements of both jackets? Ideally I want to get a feel for just how much bigger the D1 is than the B6 if that makes sense?
I’ll get you those measurements when I’m back from my trip (Sunday). If I forget, feel free to send me a private message!
