Im looking to buy a super warm N1 deck jacket and these two look to be about the warmest out there? I particularly love the look of the Heat Straps N1 but am slightly concerned they've gone overboard with the weight of the outer material as it looks as stiff as a board. with every youtube video on it showing it stood up without any support. Does anyone own a HS N1 and could comment re comfort levels: does it soften up with use? Has anyone been able to compare it to the Dehen N1? Thank you
