Made with our 15D Ultra-Sil Nano fabric with fully taped seams, this poncho is ideal for use in hot climates where a regular raincoat just won't offer enough ventilation.

Frequently Asked questions
Can this poncho be used as a tarp?
No. For this usage, choose the UltraSil Nano Tarp Poncho
Is the nylon fabric 'breathable'?
No. But a poncho has far more ventilation than a rain jacket; condensation is rarely an issue
Waterproof enough for heavy rain?
Use a poncho over a backpack: rain runs down the fabric (fabric is not subject to the pressure of pack straps)
