Love the Madness,

Love it! Lightweight, stays dry, keeps you warm!I've stayed warm sleeping out in 20˚F nights, although I wouldn’t feel comfortable sleeping in anything colder than 20˚F without some sort of additional down or fleece liner bag on the inside. I’m 6’3″ tall so I went with the long version of this bag, which gives me plenty of foot room but without being too big. The puffy, down-insulated hood is roomy enough to use a small inflatable pillow and not feel too claustrophobic. The no-draft collar and hood drawcord were easy enough to use and help to keep my well earned body heat inside the bag where it belongs. There is also a down-insulated wedge that lives alongside the zipper to cover the insulation gap when the bag is zipped up.

Excellet!I'll start by saying that it isn't winter so I have yet to test this. But this is my first down bag. After using lots of cheap synthetic bags, I can surely say this will be warm. It has a generous amount of fill. And though it may not be superlight, it is way lighter than most bags in this price range. It is a steal. I've honestly never been in anything so warm. When you get in, it instantly traps in the heat. It feels like an oven. There's a little more fill around the head and foot area. The zipper is the most snag free zipper I've ever seen on a bag. I feel confident taking this down to the mid 20's with only light layers. The stuff sack it comes with packs it down to about the size of a thermarest trail scout. The fabric inside is so soft and the shell is a light ripstop. I've had no feathers leak yet. fully lofted, it is about 3-3.5 inches thick. The vertical baffles really move well with you. Overall this bag is a great deal, especially for a first down bag.

semi-lightweight bag with plenty of roomThe bag is super warm and cozy. The material BA uses is top notch and the bag has plenty of room to lay on your side if that's your thing. I wish the bag was a bit lighter but for the price and quality it is a fair trade off in my opinion.
