Sea to Summit - Ultra-Sil Day Pack - Water-Resistant Ultra-Lightweight Backpack - 30D Cordura Fabric - Egg Sized Stuff Sack - 2-Way Zip - For Travel

Great product! Strong, light packs down to nothing. Worth the money.

Very small but the material is very thin almost transparent. Not sure how comfortable I would feel with anything of any value in there, particularly while wandering around cities. Other than that it's extremely light and packs down very small.
