Good Buy

  • Familiarity: I've used it several times

Taking into consideration it was on sale for under 200$ I would say this was a no-brainer. Lightweight, fairly compact, a good buy IMO.

As previously posted no-draft collar so I take off 1star for the misleading info in the tech specs. Also no issues with "missing down".

Great Bag for the Price

    I got this on sale and for what I paid, I think I got a pretty sweet deal. The bag doesn't leak down, it's lightweight, very warm, and pretty much does everything I could ask for out of a sleeping bag. I have used it for summer mountaineering on Rainier, Adams, and Baker as well as winter camping when overnight temps were in the teens. The bag kept me warm with just base layers on. At 6' I definitely had to go with a long. If you're looking for a warm bag for winter camping/mountaineering, this is a sweet deal.

    No Front Draft Collar, Down Missing.

    • Familiarity: I've used it once or twice and have initial impressions

    Just recently got this off SAC

    ??Was a bit surprised that a 0 degree bag would come with no front draft collar to seal around the neck. This is a major oversight in the design. Even the rear neck draft collar is a bit skimpy. This makes it impossible to seal in the air your body had warmed and you feel it blowing out past your face every time you move. The zipper draft tube just continues all the way up and around the top edge. This may be a good way to eliminate several steps in the manufacturing process, but this is not a neck draft collar, this is the part that should be on your face when you cinch the opening all the way down to a blowhole. Keeping that part down on your neck will leave way too much exposed in zero degree weather & let tremendous amounts of heat escape. It also bunches up when drawn closed and does not seal.

    The upper face gasket, around the hood is also very skimpy and does not prevent the cord from pressing into the bridge of my nose while again, not providing a good seal to trap heat.

    ??Aside from that, several of the baffles over the torso area are missing a substantial amount of down compared to the leg area and top of the chest, the one over the abdomen being nearly empty, it's impossible to distribute it enough that there aren't complete voids in the insulation. There is no way I can trust this bag to keep me warm in zero degree or anything close to it.??The bag came with a cotton storage sack which probably should be a bit bigger & a stuff sack. A compression sack instead of a stuff sack would have been much preferred.

    600 fill Down, on the economical side resulting in a bit larger stuff sack size.

    great for the price

    Just picked up this bag of SAC. Used it this past weekend tent camping with the temps in the mid 20's. the bag was plenty roomy and i fit in it perfectly at about 6' tall. first time using the pad straps. didnt enjoy them so i took them off. found out the only real downfall to this bag after that... some insulation was left out of the backside of the bag thus needing to be on a pad. when i rolled over with the bag my back got pretty cold. small pet peeve for me was the lack of a stash pocket. no condensation except the 3rd night which i figure was cause my tent was under an inch or so of snow and the ventilation was blocked a bit.
