The Sea to Summit Ultra-Sil Nano Tarp Poncho is one of the most packable ponchos on the market, due to the 15D sil-coated fabric. It also absorbs less water than heavier silnylons.
This poncho offers generous coverage while worn as a poncho than other ultralight ponchos, but is a bit narrow when used as a tarp. So, it’s better suited for those who need raingear rather than those who need sleeping shelter for stormy weather.
