Its almost time for my annual Q Adventure nad as I am pooring over maps and dreaming I looked at my map case  (Chinook) and need a new one. The Chinook was a complete waste of money and never was "Waterproof", resistant yes waterproof   not at all.

So far my choice I have narrowed my choices down to:

Dry Pak (You need to Login or Register to view media files and links)

Sea Line (You need to Login or Register to view media files and links)

The old style Sea Line is not  Waterproof, as I have a friend who has one and I have pictures of his maps on the clothes line at camp  

This year my son age 12 is going to start carrying a map in the bow, so he can better learn to navigate. I am interested in 12 x 16 size to aid him in the learning process and eliminate the constant turn, fold, flip routine.

Any suggestions and advice would be appreciated.

I have no experience with either of the two cases you mentioned.
I use a Granite Gear map case that isn't waterproof by design as it just has a fold over top secured with Velcro.

I've had great luck with using zip-lock type plastic bags to put my folded maps in. I found some on line that are 2 gallon I believe. Laid flat, they fit the clear portion of my map case. I fold and stack my maps in relationship to my line of travel. I've found that by squeezing out all the extra air and zipping them, I end up with a waterproof map case.
You could do the same with your old Chinook. To avoid the flip and fold, you could put one map per zip lock bag. I think you could do it so you just flip the bag to continue on with the line of travel.
I'm using McKenzie maps but unless your using just one map like a Chrismar, it should work okay.

I run a granite gear case also, it seems to be of a similar design to the piece that is mentioned above. It is also true that I refold multiple times during the day and run the "lake finder" maps in ziplock style bags inside the case. I also add notations in sharpie to the Fisher and Voyager maps as it strikes me. I believe the GG case is somewhere around 15-18 years old, no construction issue except i did replace 1 of the cam style buckles in the last couple of years went 1 of the rention tabs on the plastic buckle finally gave out. It has 100's of days in trips on it , most likely 1000's. Not sure if they are still the same but I would do it again. It's hard to loss something purple I might add, and the price was right to boot. Oh if that map case could talk!

Hey Saltedleech - before you buy, check out The Boundary Waters Journal Trading Post. I've had his map case for 6 years. I believe it is a  beafed up version of the GG one. It works perfect for me. It is not real big, about the size you are looking for.  You can only view 1 side but it keeps water out well and it is tough. I had the plastic clasp (like the clasp on most packs )snapped around my thwart and It was strong enough to hold my eagle fish finder on when a floppy northern got caught in the transducer cable . I spray the cordura back side each year w/ a heavy coat of camp dry. I think it is around $25. Good luck!

I have a GG case with a ziploc tip closure. I really like it but it isn't very durable. The first one I bought only lasted about 3 seasons but I liked it enough that a replaced it with the same thing anyway. The first one basically dry roted and got a few cracks. The one I have now doesn't seem to be doing that at all, so far (this will be its third year) Just bad batch on the first one? Otherwise I really like it.
