Description
The Ultra-Sil Nano Poncho was designed to cover you and your backpack while retaining a tiny packed size and remaining extremely light. 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.
Features
- Waterproof 15D Ultra-Sil Nano fabric
- Long back panel for use with a backpack
- Fully taped seams
- Packs into its own stuff sack
Technical Features

One of the lightest coated fabrics that Sea to Summit manufactures, the 15 Denier Ultra-Sil is a siliconized nylon fabric with a polyurethane (PU) inner coating for mild waterproofing. This ultralight fabric has a 1,200mm hydrostatic head.

The Ultra-Sil Nano Poncho and the Ultra-Sil Tarp Poncho are PFC free.
The Nylon Tarp Poncho has a DWR impregnation until 2022, but will be completely PFC free from 2023.

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)
