    Probably not the best thread for asking this, but...

    Any good practices how to measure the internal dimensions of a pack.

    I'm trying to find a dry bag that would fit a bit like the bag liner you can order from Atom for their packs.

    Would they differ a lot from the outside dimensions?

    I don't know, but the inside floor might be a bit tricky to measure from outside, hence asking.

    I think accuracy of fit would depend more on what material you're going for than cut of the bag. DCF is less good at padding out awkward shape corners as I understand so might need to be better fitted than, say, a 15D/20D nylon drybag.

    It would be DCF. I already have a Gram Counter 20l or 30l bag, but the fabric tends to fall on itself when the bag is semi empty and when searching for things inside making innerds look like there's nothing but the bag itself.

    Osprey have updated their Talon / Tempest line:,145,11,146

    There's a new, fancy pro version made with their supposedly more-durable-for-the-weight nanofly fabric.

    Interestingly the Talons have put on some weight. The new Talon 22 weighs about 900g, the old one 600g(according to Cotswold, maybe that's the s/m, mine in m/l weighs 782g). The new Talon 33 about 1.1kg, the old one 860g (dependent on size chosen).

    Nearly 2 ton for a nearly kilo day pack... strange times indeed...

    Nice one, have to see if that can be done.

    When I make mine to fit exact packs, I just measure the outside dimensions. You can't go far wrong.

    My strong advice is don't go undersize at all as it just loses packing space. Err on oversize by and inch or so and much better is a tapering profile as the slip back into the pack better when full. My tapering packing cells/liners are so much better to use than straight ones as they just drop into the pack when fully loaded.

    I had to do this a few times to compare packs with makers giving capacity in various confusing ways (with and without external pockets or with or without "extension" volume etc ...). Circumference is quite straightforward to establish (sometimes different top and bottom). Circumference gives me any of the relevant measures (diameter or radius) to calculate volume based on height to where the extension collar starts. As others said, the difference between inside and outside measurements is usually neglectible...
