    Packing more for colder trips.

    It's a shame you have to trek with a heavier backpack when you're trekking in freezing temperatures—winter attire is much heavier than summer—but at least the Therm-a-rest Oberon Sleeping Bag packs down to the size of larger water bottles. Its 800-fill down insulation is ridiculously lofty, compressible, and surprisingly light for how warm the bag feels. The down is treated with Nikwax for hydrophobic properties that keep the down lofty and warm in moisture-riddled environments. Therm-a-rest lined the bag in ThermaCapture to reflect your body heat back to you for a boost of warmth. You'd think this lightweight bag wouldn't come with any additional features, but the Oberon has sleeping pad connectors and blanket loops for fully-featured convenience.

    New favorite bag

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

    I got to take the Oberon for a "test sleep" with Thermarest in January, and I was thoroughly impressed. The weather was... damp. It snowed about a foot of Cascade Concrete overnight, and the inside of our tent felt like a rainforest. But golly, I was as warm and dry inside the Oberon as I've ever been on a backcountry adventure. In my other bag I would've been a shivery mess. I've been converted to a believer in hydrophobic down. I usually sleep cold and was a little worried about the 14deg comfort rating, but it turned out to be plenty warm enough (even with my soggy gloves and boot liners in the bag with me). I immediately said buh-bye to my old bag and upgrade to this one.

    Unanswered Question

    Is the stuff sack size listed with the bag in the compression sack or just a stuff sack?
