I have 2 seasons on the super down haven jacket. I like it more everytime I wear it, and I use it a lot between whitetail stand hunting and thermal predator hunting. I can't compare it to other high end down whitetail jackets, but it's warmer than any other jacket I own. Face fabric is quiet and there isn't any loud shells inside so you can move without making any more noise than a standard fleece jacket. Wrist seals, the extra down baffle that goes around the back of my neck and the low draw cord makes an incredible seal, enough that when you lean against something it pushes the jacket away from my chest from the air pressure. The warmth and comfort really is unlike any jacket I've used. I don't put any heat packs into the jacket unless it's under 20 and I'm gonna be on stand for more than a few hours and all I wear under it is a t shirt. Pockets are mostly well designed. The front chest pockets are roomy and easy to access. Only complaint I have with the pockets is that the lower heat pack pockets are too low for me, they end up below my pants/bibs. Maybe that's how they were designed and I don't understand them, idk. But the upper heat pack pockets on the chest are perfect. Also other interior pockets to drop heat packs so not a big deal.
I pair it with the proximity pants as I think the haven bibs would be too warm to move around in.
That was kind of a ramble but to sum it up, I bought the jacket fully expecting to have buyers remorse and return it after a trial, but I'd buy it again for twice the price. I really don't think there's another jacket in its league for warmth/weight/quietness, could be wrong.
