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 comfort rating of 13F (-11C) and an EN limit of 0F (-18C). The shell is constructed from GORE-TEX Windstopper 30D 2-layer nylon ripstop at 57 g/m², delivering windproof, highly water-resistant, and breathable protection that keeps 800-fill goose down performing even in wet, exposed conditions. The 15D nylon ripstop lining at 34 g/m² keeps interior weight low, and the regular version packs down to 692 cubic inches (11.3 liters) at a compressed size of 17 by 9.5 inches. The regular fits users up to 72 inches (183 cm) tall, while the long accommodates up to 78 inches (198 cm). Thoughtful construction 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 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, with multiple testers confirming it performs at or beyond its 0F rating in real-world conditions. The 850-fill-power down, mummy cut, draft collar, and face gasket are frequently highlighted as key contributors to its thermal efficiency. Its impressively light weight and small packed size for a 0F bag are recurring points of admiration. The Gore-Tex Windstopper shell earns specific praise for wind and moisture resistance, making it well-suited for open bivouacs and severe alpine conditions. The most common complaints center on the narrow, restrictive fit that some find uncomfortable, a zipper prone to snagging on the draft tube fabric, and a very thin shell that requires careful handling to avoid tears. The high price is also noted as a barrier, though most reviewers consider it justified for the performance level.
