About this product

The Mountain Hardwear Phantom Windstopper Sleeping Bag is an expedition-grade mummy bag engineered for serious alpine and mountaineering use, with a temperature rating of 0F (-18C) and an EN Comfort rating of 13F (-11C). 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 severe mountain conditions. The 15D nylon ripstop lining (34 g/m²) keeps interior weight low, and the bag compresses to just 17 x 9.5 inches (43 x 24 cm), with a packed volume of 11.3 liters in the regular size and 12.1 liters in the long. Total weight is approximately 3 lb 10.3 oz (1,652 g). The expedition mummy cut accommodates users up to 72 inches (regular) or 78 inches (long), with a 64-inch shoulder circumference in both sizes. Key thermal features 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 draft tube. A compression sack and 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.
