These dry bags are excellent, particularly for the price. On last year's Colorado River trip our bags worked great (not much to it) but a friend's much nicer-looking units from [@] leaked right through the seams.Remember not to over fill these, and they work great. Excellent for canoeing and for c... Read More

  • “If the dimensions are 33 inches by 13 inches, how is it possible that this is a 70L bag? I thought the area of a cylinder was 2prh+2pr^2? That would make this more like a 1600 cubic inches bag, which is more like 26L. Am I losing my mind?”
    Asked by MrsCarpenter from Tonasket on 6/2/2015 3:06:50 PM
    • I measured the width to 19 inches when flat. That makes just 12 inches when pulled into a circle. I don't think you'd want to go more than about 28 inches high to still allow a good roll at the top. Volume is radius squared * pi * height = 6^2 * 3.14 * 28 = 3167cubic inches, which is about 52 liters. So yeah, not quite 70, but lots bigger than 26. I have several 25L drybags and this one is definitely a lot bigger. In comparison I would have guessed well beyond twice as big rather than just about twice as big. But a lot depend son how far you roll.

  • “I have a 65 L backpack. I'm going on a trip that entails several river crossings. Do you think it will work to simply put the backpack into this drybag?”
    Asked by Maineiac from Arizona (relocated from maine) on 1/25/2014 4:54:03 PM
    • I understand the theory, but I don't believe it'll fit. Especially to be totally sealed for a river crossing. I suggest taking your pack to a local store with similar (if not the same) drybag to test it. Save yourself some aggravation and money. Good Luck!

  • “I'm going on a camping trip that allows two bags no more than 45lbs each. They will hold normal camping gear and biking gear/clothes for a 5 day camping & biking trip. Will these bags work? Are they large enough for my purposes? Thanks in advance!”
    Asked by Krystle V from East Lansing, MI on 5/9/2013 5:47:30 PM
    • Two of these bags will be plenty large for your needs.

  • “AnswerThis
    The capacity listted for this bag is 4380 cubic inches. Conversion charts state that this is equivalent to 71 liters not 50 liters.
    Is your answer the capacity after the bag is rolled to close?”
    Asked by Beth from Colorado on 4/7/2013 11:01:53 AM
    • You are correct it appears someone use an incorrect conversion back in 2011. It is more like a 70 liter pack. The capacity is for when it is rolled closed.

  • “Is the length stated for the extra large bag (33") the entire length before rolling it, or the length of the usable enclosed storage space after it has been rolled? I have a tent that measures 28" long.”
    Asked by kate from seattle, wa on 8/26/2012 12:00:00 AM
    • The length is taken of the entire bag before its rolled. Thanks for asking.
