About this product

The Mountain Hardwear Phantom Windstopper 0F/-18C is an expedition-grade mummy sleeping bag engineered for serious alpine missions where wet conditions and open bivouacs demand uncompromising protection. The outer shell is constructed from GORE-TEX Windstopper 30D 2-layer nylon ripstop (57 g/m²), a windproof and highly water-resistant fabric that keeps 800-fill goose down dry and lofting even in severe mountain weather. 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 (43 x 24 cm). The expedition mummy cut accommodates users up to 72 inches (183 cm) in the regular and 78 inches (198 cm) in the long, with a 64-inch shoulder circumference in both sizes. Warmth retention is reinforced by vertical side-wall baffles, a shaped draft collar, an oversized down-filled face gasket, and a contoured footbox. The EN comfort rating sits at 13F/-11C, with a limit rating at the 0F/-18C temperature rating. A nylon compression sack and mesh storage sack are included.

What people are saying

Reviewers consistently praise the Phantom Windstopper 0F for its exceptional warmth-to-weight ratio, calling it one of the best 0F bags on the market. The 850-fill-power down, full-length draft tube, shaped draft collar, and contoured footbox earn repeated acclaim for keeping users genuinely warm at or below its rated temperature. The Gore-Tex Windstopper shell is highlighted as a standout feature for bivy and exposed alpine use, offering windproof and highly water-resistant protection. The most common criticisms are the snug, restrictive mummy fit (noted as uncomfortable for those who like to move around), the added weight and bulk of the Windstopper shell compared to the standard Pertex version, and the steep premium price. Some reviewers also note that the Windstopper shell breathes less efficiently than the standard shell when used inside a tent, potentially trapping body moisture.
