About this product

The Mountain Hardwear Phantom Windstopper Sleeping Bag is an expedition-grade mummy bag engineered for serious alpine use, rated to 0F (-18C) with an EN T-Extreme rating of -38F (-39C). The outer shell is constructed from GORE-TEX Windstopper 30D 2-layer nylon ripstop (57 g/m²), providing windproof and highly water-resistant protection that keeps 800-fill goose down performing even in wet, exposed conditions. The 15D nylon ripstop lining (34 g/m²) keeps interior weight minimal, with the regular version weighing approximately 1,652 g total and packing down to 17 x 9.5 inches (692 cubic inches). The long version accommodates users up to 78 inches (198 cm) tall. Thoughtful cold-weather details include vertical side-wall baffles for maximum loft, a shaped draft collar, an oversized down-filled face gasket, a contoured footbox, and an anti-snag zipper with a glow-in-the-dark pull. Both a nylon compression sack and a mesh storage sack are included.

What people are saying

Reviewers consistently praise the Mountain Hardwear Phantom Windstopper 0F for its exceptional warmth-to-weight ratio, calling it one of the warmest backpacking bags available for its size. The 800 to 850 fill-power down, four-chamber hood, wraparound draft collar, and full-length draft tube earn repeated compliments for sealing out cold effectively. Its impressive compressibility and lightweight build are also frequently highlighted as standout strengths for winter and alpine use. The most common criticism is the narrow, tapered mummy cut, which some find restrictive for those who move around while sleeping. A few users also flag the delicate shell fabric as requiring careful handling, and the premium price point is noted as a significant investment. Some reviewers caution that the true comfort threshold sits closer to 12 to 15 degrees F rather than the stated 0F rating.
