Integral Designs says:
The Silshelter is an ultralight siliconized nylon tarp specially shaped to set up on a hiking pole as a two person stand-alone shelter. Intended for use in conjunction with a bivy in above treeline conditions. Non slip Neotek pole cap holds hiking pole in place at reinforced apex. with a second pole wrap prop-point in the centre of the shelter.
There are 21 webbing tie outs on corners and edges (one on the outside of the pole cup to enable suspension from a tree) and 3 webbing tie loops on the body of the tarp. The front entrance flaps can be left open for ventilation or overlapped and staked for a weather tight closure. The Silshelter has no zippers. Pitch off ground level for best ventilation. The Silshelter will attach to front of many tents as a simple vestibule.
