A footprint is a separate groundsheet that is customized to fit each specific model of MSR tent. We highly recommend using an MSR footprint under your tent as it serves multiple purposes. Firstly, it helps to keep your tent floor clean and dry. Secondly, it provides an extra layer of protection to the floor, preventing excessive abrasion and extending the life of the tent.
In addition, some MSR tents can be set up with just the footprint and fly, creating an incredibly lightweight and minimalist alternative to a full tent. This setup is ideal for those who prefer to travel light and fast. So, investing in a footprint is a wise decision that can benefit you in multiple ways.
