The ME Snowline sleeping bag is designed for expeditions in extreme cold weather
The Snowline sleeping bag is part of ME's Extreme Expedition range and is designed for serious cold-weather use, including mountaineering and backcountry ski trips. The bag utilises a complex baffle system to maximise warmth and eliminate cold spots. V-shaped baffles in the chest and upper legs maximise down overlap, while trapezoid baffles prevent down migration across the middle of the bag. The bag also features a seven-baffle, low-volume anatomically shaped hood, which minimises weight and provides exceptional down control for long-lasting insulation.
The ME Snowline sleeping bag has been tested in extremely cold environments, including in the Arctic Circle and the Himalayas. Users have reported that the bag kept them warm in temperatures as low as −22.7°C, with one user stating that it was the warmest sleeping bag they had ever used. The bag has a comfort rating of −9°C and a comfort limit rating of −17°C, although ME believes that the bag can perform beyond these temperatures.
The design of the Snowline sleeping bag prioritises usability, in addition to warmth. The bag has a mountain fit, which provides a roomier experience when compared to slimmer and lighter alpine-fit bags. The EXL® system in the Expedition bags also provides a roomier fit, while improving loft and thermal efficiency. The bag features a full-length Gemini™ zip baffle, with an integrated collar and Lode Lock™ closure, which combines the advantages of a magnetic fastener with those of a mechanical lock.

It is lightweight and made with high-quality goose down
The Mountain Equipment Snowline sleeping bag is a lightweight, expedition-class sleeping bag. It is part of the brand's Extreme Expedition range, designed for serious cold-weather use, including mountaineering and backcountry ski trips.
The Snowline sleeping bag is filled with 831g of high-quality goose down, with a minimum fill power of 800. This goose down is sourced from Ukraine and has a minimum down cluster content of 90%. The down is CODEX-approved, ensuring that it meets high environmental, ethical, and animal welfare standards.
The bag's lightweight design is achieved through the use of a 10 denier outer fabric. The specific fabric used in the outer shell varies depending on the model. Some Snowline bags feature a GORE-TEX WINDSTOPPER® 10 denier outer fabric, which is highly breathable and water-resistant. Other models feature a GORE-TEX® INFINIUM™ 10-denier outer shell, which offers similar benefits of durability, breathability, and protection against the elements.
The Snowline sleeping bag's design includes complex baffle systems to maximise warmth and comfort. V-shaped baffles in the chest and upper legs eliminate cold bridges, while trapezoid baffles prevent down migration across the middle of the bag. The bag also features a 7-baffle, low-volume anatomically shaped hood for exceptional down control and long-lasting insulation.

The bag is breathable, water-resistant, and features a hood for added warmth
The Mountain Equipment Snowline sleeping bag is an exceptional bag for very low temperatures. It is lightweight, breathable, and water-resistant, making it ideal for serious cold-weather use, such as mountaineering, backcountry ski trips, and expeditions in extreme conditions. The bag's breathability is enhanced by its complex baffle system, which includes vertically aligned V-baffles on the chest and foot piece, and trapezoid baffles throughout the rest of the bag. This system helps to maximise thermal efficiency and prevent cold spots, ensuring that condensation from your breath does not affect the insulation.
The Snowline bag features a hood for added warmth. The hood is designed with seven baffles to provide exceptional down control and long-lasting insulation. It minimises weight and has less deformation when cinched down, offering single-handed closure with easy-run drawcords. The entire bag, including the hood, is lined with a GORE-TEX INFINIUM™ 10-denier fabric that is durable, lightweight, and highly protective against snow and condensation. This fabric is key to the bag's water resistance and breathability.
The outer fabric of the Snowline bag is also designed with breathability and water resistance in mind. Made with a lightweight version of ME's well-known Drilite fabric, the outer shell is highly water-resistant and breathable, allowing excess moisture to escape while keeping external moisture out. This outer fabric is key to ensuring the bag remains dry and comfortable, even in extreme conditions.
The combination of a breathable and water-resistant outer fabric, a complex baffle system, and a well-designed hood makes the Mountain Equipment Snowline sleeping bag an excellent choice for those seeking warmth and protection in cold and challenging environments. Its features ensure that condensation and moisture do not build up inside the bag, contributing to a comfortable and dry sleeping experience, even in extreme temperatures.
