I bought Alocsac 19x20 inch oder proof ect. stated weight is less than an oz my scale ranges from 1.44 to 1.58 oz each. Just a warning. Bought from Campmor.

I bought from bpl, and the states weight was 14-15g less than the actual weight as well. I bought the largest one, on two different scales it game up as 40g each, i would not have bought these if i knew they were that much heavier than my current dry bags.

I just got a set of the Outdoor Research Dry Ditty Bags at Wallmart for $10. They must have been priced wrong. Looks like the street price for the same set of 3 is like $27. The 9x9in is about 1oz. The 5x5 is .8oz on my scale. Not as light as some plastic bags but more durable and for $10 it seemed like a good deal.
