Hillebergs are terrific tents, but heavy and expensive. If I did long duration winter travel, I'd want one! But they're overkill for a night or two in the snow, particularly below timberline. Even ADK Winter Mountaineering School considers a 3 season tent adequate to a Northeast winter peak bagging trip. Student handbook at
www.winterschool.org says:
Tent:
Most modern dome, tunnel, or “A” frame tents designed for 3-4-season use are acceptable. The tent should have a breathable body, a waterproof fly, openings that close tightly, and the strength to withstand winter winds. Large areas of mesh in the ceiling, which is becoming more popular in many 3-season tents, is a drawback as snow may get in during a storm. Be sure to seal all seams if they are not factory sealed.
Snow Stakes:
Necessary if your tent needs stakes. Skewers or standard pegs will not hold in soft snow. An alternative is to fill any stuff sacks with snow and use them as “dead men.”
Groundsheet:
A groundsheet will protect your nylon floor from the abrasiveness of the snow and other forest products.
Snow Shovel:
A collapsible, lightweight snow shovel is very handy for constructing snow kitchens, digging snow caves, and creating emergency shelters.
