If you own the Mountain Hardwear Helion 2 tent the Helion 2 Footprint PL is a must have. Protecting the floor of your tent from rocks sticks or anything else that might cause damage will prolong the life of your tent and keep you warmer as a footprint acts as insulation between you and the ground. Mountain Hardwear has designed the Helion 2 footprint specifically for the Helion 2 tent so you will have a perfect fit. Take just the footprint poles and fly and you have a lighter weight shelter if you need to move fast & light.
