Never let rain spoil your fun outdoors again with the Heron Rain Tarp. This 8.6oz (243g) Silpoly hexagonal rain tarp is ultralight and won’t weigh down your pack. Traditional lightweight tarps are often made from 1.1oz Silnylon that can stretch out when wet, but Hummingbird’s Rain Tarp is made from a newly developed 0.9oz Silpoly which provides a full coverage that doesn’t mist through or stretch.
