The Sierra Designs Mountain Meteor 2 Footprint adds function, durability, and versatility to any Sierra Designs tent. Footprints protect your investment from dirt, gravel and sharp objects. If mild weather or a particular trip demands a fast-and-light approach, try the "Fast Pack Mode" by using just the Fast Pack Footprint™ with the rainfly and poles to make an ultralight shelter. On average, it accounts for a weight savings of 30%, making it another tool in your fast packing arsenal.
