The Sublite Silnylon Model weighs only ONE OUNCE MORE than the tyvek model (18.5 ounces total), but has improved rainproofness and slightly less breathability.
Sublite Silnylon Model availability and pricing are as yet to be determined (but i bet it's soon) :)
The Sublite Silnylon features an adjustable rear ventilation flap as well as the standard front vent.
The Sublite Silnylon has the exact same dimensions as the tyvek version. 6' 2" tall model shown inside tent. There is abundant gear storage room at the head, foot and sides.
The Sublite Silnylon uses the exact same dual trekking pole or poleless set up as the tyvek version.
If you want to see one "in the flesh", Henry has both the Sublites on display right now at the PCT kick off at Lake Morena County Park in California. Stop by and tell him thanks for listening to us!
