Summary:
The Black Diamond Mega Light Shelter for four people is a moderately lightweight and spacious pyramid tent suitable for everything from an emergency shelter, to cooking tent, to basecamp sleeping tent, and works in any climate, weather, and setting. Although this tent offers minimal protection from critters and bugs, it works well to defend against rain, snow, and wind, particularly with an added groundsheet and some creative thinking. Although not the lightest shelter on the market, the price makes it a bargain for the size and ease of assembly, although beware, it does not come seam-sealed and must be done by hand.
