Marmot Scandium Sleeping Bag
The Marmot Scandium sleeping bag is leading the way in with a unique fill construction. The top of the bag is 650 Fill Power Down with Down Defender while the bottom is Marmot’s own SpiraFil synthetic insulation. If you’ve ever slept multiple nights in a row in an all down bag you know that the bottom can get compressed and lose some of it’s warmth. SpiraFill combines spiral hollow fibers and small polyester fibers which won’t compress as much as down underneath you. It also performs better if your sleeping bag gets wet. At the same time we know that down is incredibly warm and comfortable. That’s why Marmot put down on the top, to keep the ultimate warmth and comfort while keeping your bottom protected. To help with the “down loses warmth when wet” conundrum Marmot uses Down Defender, a specially treated down that stays dry 10 times longer than untreated down. It also dries 30% faster than untreated down. Not only that, but Down Defender also helps the down maintain it’s loft.
Now, to the most important aspect, I stayed warm. I used the Scandium for a weekend of camping in Vermont where I was 1400 feet up the side of a mountain with only a bivy tent for shelter. The overnight temperatures dipped into the upper 30s and I was happy as a clam sleeping in my t-shirt and pants. Actually, I might have been a tad on the warm side and could have switched into shorts if I wasn’t so tired. The Scandium is rated for 20 degrees and I would be comfortable using it to that temperature. Mind you, I would have more layers on if it got into the 20s. Marmot also includes the EN, European Norm, rating on the bag. This is a government test that is required for bags sold in Europe. It includes the temperature that is considered the most comfortable for a standard women, the lower limit for the standard man, and the extreme limit. I would not use the sleeping bag to the extreme limit unless it was an extreme emergency.
Don’t let the colder weather keep you inside. The Marmot Scandium sleeping bag is great for colder weather camping. You get the best of both worlds with the SpiraFil and down. The Scandium also comes in long for individuals taller than 6 feet.
