Freefly Packable DuffleWhy It Made The List Pack this down, forget its there, then pull out a genuinely weatherproof 30 litre duffle when you need extra carry. It stashes into its own pocket or the included compression sack, so its perfect for overflow luggage, day trips, or bringing something back home. Sealed seams and sealing zips help protect contents on wet travel days, while reinforced UHMWPE wear panels take the kind of abrasion that usually kills lightweight bags.
