Steve Swrote a review of Patagonia Black Hole 60L Duffel on March 3, 2018
Familiarity: I've used it once or twice and have initial impressions
I bought this in a hurry for an international trip so I could bring some ski gear and THIS THING ROCKS! The bag had plenty of room for my stuff and the backpack conversion worked great. The only hiccup was that it took me a second to figure out how to attach the backpack straps, but a quick Google search cleared that up for me. This thing is a great option. Durable, big, and carries well.
