I love it when a plan comes together.

Ingredients:
One Sealine Baja 10 dry bag
One cheapo foam sleeping pad
One daypack

Recipe:
Cut one 11 ¼” x 22 ½” rectangle and one 25 3/8” x 11 ¼” rectangle from the foam pad.

Cut one 7” circle and one 8” circle from the pad. I actually used scraps of ¾ minicell for the smaller circle and ½ minicell exercise for the larger circle, but all of this can be cut from a foam sleeping pad with lots of leftover (probably enough to insulate a second bag).

The smaller rectangle and circle are sized to use as removable interior insulation/padding; just stuff the 7” circle in on the bottom, coil the 11 ¼ x 22 ½ rectangle into a stovepipe, insert it in the bag and let it go. Reverse that process for easy-out rinsing or cleaning of the dry bag innards.

This Baja 10 bag is going to be a dedicated cooler, and I have a little room to play with in the daypack*, so the larger rectangle gets contact cemented around the outside of the bag and the larger circle glued to the bottom. Double insulated and I can remove the inner foam for more capacity, or remove the whole double insulated thing and have an empty day pack to use.

Time to test load the pack*. Just for demonstration purposes you understand, using whatever is handy, into the insulated Baja bag go ten 12oz cans of Yuengling Chesterfield (with room here and there for ice). Remove the inner sleeve and it’ll hold even more if needed.

*The pack. I had very specific criteria for the pack size and style. Ideally something with a compartment width and height sized not too much bigger than the dry bag’s outer foam sleeve diameter, with a drawstring/flap top opening for easy access (and fewer critical zippers) and a couple of exterior pockets for miscellaneous small gear. And, what the heck, padded shoulder straps.

Back into the bowels of the fabulously funky and chaotic H&H I go with the Baja 10 bag in hand

I show Clyde what I want to do and he leads me to a couple of flap-top daypacks that will work. Almost; this one is a little too big, this one a little too pricey…

But, hung way up high we find the perfect (dusty) candidate. Quick-release buckle flap top with inner drawstring, big pocket on the back and another thinner pocket on the top flap. And it’s urethane coated on the inside. It’s as close to perfect as I could ask.

I check for the price and now it’s perfect. It has no packaging, no manufacturer tags or pricing. It has dust, and a handwritten price tag on a piece of scrap paper.

Perfect and cheap.

FWIW it’s an “Outbound”, and the company is still is business

I’m thinking that a doublewall insulated, airtight cooler bag oughta stay cold for a long, long time.

I like it, and I have enough leftover foam to eventually make the beta model after some, um, field testing.
