• The ditty sack is pretty small....5-6 liter. Both of the bigger ones have tags inside that say 15L. Hope this helps. Brent

  • The specs say the ditty bag is 244 cu.in which converts to nearly 4L. The 2 larger dry bags are listed as 15L each. Just different dimensions for the 2 larger ones. Hope this helps.
