The Sea to Summit Sentinel Footprint adds abrasion and water protection to a solo setup without weighing down a fast-and-light mission, precisely sized to avoid water pooling beneath the tent during heavy rain. A Fly Only configuration strips the pitch down further when speed matters more than full coverage, backed by Hypalon attachment points that keep the connection secure at the pole tips. What Our Gearhead(R) Experts Are Saying:"I ran this on a solo fastpacking trip where every ounce mattered, and it never felt like a compromise even through a night of steady rain. Packing it down into its own pouch the next morning took seconds, which is exactly what a fast-and-light setup needs."
