You can tell I’ve got too much time on my hands! After some trial packing this afternoon, I thought I’d try the combination of my Pipedream 600 with my GG Mariposa. It fits! Perhaps I shouldn’t be surprised as the Mariposa absolutely swallows gear. The pack body is a bit wider than the Ohm and it makes all the difference. It also has more flexibility with its mesh pockets. So I’m now thinking of returning to the Mariposa as my pack of choice. It feels so comfortable. Decisions, decisions!
