Here's what others have to say...



  • 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.

Where are these made?


I love my bags. Work great

    Went on a 2300+ Mile motorcycle and camping trip, ran through the rain for 2 days total. Bags left content completely dry even at 80 MPH! Sturdy too!


    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.


    Keep your gear dry

    • Familiarity:I've put it through the wringer

    This nimbus sack is great for keeping your gear dry during water excursions. Highly functional, durable and BLUE!!---my favorite color
