    excellent dry bags

    • Familiarity: I've put it through the wringer

    We love these bags. Sturdy and watertight,but lighter weight and less bulky than other styles, great for tucking into the hatches. Started using them about 3 or 4 years ago for kayak trips and haven't had to retire one yet.


    • Familiarity: I've used it once or twice and have initial impressions

    I bought this dry bag to use on a overnight SUP trip. It worked great and kept my gear dry. Did everything it was supposed to do. However, I returned it.... Every time I took it off the board and put it in the dirt, or next to some bush I was worried I was going to puncture it. I returned it to purchase the SealLine Baja, I think that'll be the ticket for my purpose.

    When the thicker Baja bags are too much

    • Familiarity: I've used it several times

    I have several SealLine Baja nags and they are a little bit stiff in the smaller sizes (5-10Lt) for sea kayak hatches. I wanted something a bit thinner (not for hard items) that will fit better around the stiff stuff inside the hatch of sea kayaks. Nimbus seems to be the ticket with its shiny "kind of sticky" surface that creates a better seal when rolled down than some other fabric dry bags (the fabric wicks when wet).

    Can't report on durability since that opinion will come with years of use.
