We know, you're thinking to yourself: 'I must be reading this wrong!' You're not, the Marmot Trestles 0 Degree Spirafil Sleeping Bag does cost this much and it is really zero-degree rated. Marmot outfitted this winter sleeper with all the technical features for a night in a snow cave and added a few extra like a hood that shares the same construction as their expedition-ready 8000m jacket. Pining after the loft of your down bag and hesitant to switch to synthetic? Fear a loss of loft no longer, because SpiraFil insulation uses two types of synthetic fiber to keep things fluffy. Ahhh... that's the ticket.

• DWR-coated shell material fends off light rain and moisture so your bag and insulation stay drier in inclement weather
• Lofty SpiraFil insulation combines hollow fibers and denser, solid synthetic fibers in order to offer a balance of warmth, softness and compressibility
• Insulation fibers are thermally bonded so the insulation maintains its loft and shape longer, meaning more warmth and a better performing bag in the long run
• An overlapping series of internal insulation shingles creates the Wave Construction which allows for more efficient use of insulation so you stay warmer without needed additional insulation that would add weight
• Easy to reach draw cords make adjustments easy when you're bundled up
• Trapezoidal foot box matches the shape of your feet, wider in the toe area and narrower in the heel so you have more foot room and warmer feet
• Zipper garages cover up the two-way sliders from the elements so they operate smoothly every time

Bottom Line: Toss it in your pack for a trip into the wild or the back seat of your car as a winter safety measure for those long drives out into the boonies.
