The SEA TO SUMMIT Ultra-Sil poncho jacket is a lightweight, packable rain shell in blue, designed to cover both wearer and backpack while remaining extremely compact. Constructed from waterproof 15D Ultra-Sil Nano fabric with fully taped seams, the poncho offers protection from rain and wind while ensuring good ventilation compared with conventional raincoats. Its roomy poncho cut and hood make it easy to layer over clothing and gear during travel, trekking, and other outdoor activities.
Advantages
The poncho combines a very small packed size with low weight, making it convenient to carry on multi-day trips or as an emergency waterproof layer. The long rear panel provides coverage for a rucksack, and fully taped seams increase overall waterproofing. It packs into its own stuff sack for compact storage and quick deployment.
Suitable for
- Backpacking and trekking where weight and packability matter
- Travel and commuting as an ultralight rain shell
- Day hikes in warm or humid climates needing ventilation
- Emergency rain protection kept in a pack or luggage
When it may not be suitable
The poncho’s very lightweight 15D fabric and loose poncho cut prioritise packability and ventilation over long-term abrasion resistance and tailored fit. For cold, windy conditions where thermal insulation and a close fit are required, or for activities with high abrasion risk, a more robust, fitted rain jacket may be preferable.
Key specifications
- Material: 15D Ultra-Sil Nano waterproof fabric
- Seams: Fully taped for waterproofing
- Design: Poncho-style with hood and extended rear panel for backpack coverage

How to use
Unpack the poncho from its stuff sack and pull over head, adjusting the hood as needed. Position the extended rear panel over your backpack for full coverage and allow room for ventilation beneath the poncho. After use, shake off excess water, allow to air dry if possible, then fold and stow back into the stuff sack for compact storage.
What to consider before purchase
- Needed level of durability versus weight and pack size
- Whether a loose poncho cut suits your preferred activities and layering system
- Climate and expected conditions (best for warm or humid environments)
Usage recommendations
Use the SEA TO SUMMIT Ultra-Sil poncho as an ultralight, packable rain cover when you prioritise low weight and ventilation; avoid relying on it as your sole waterproof layer in cold, highly abrasive, or prolonged wet conditions.
