Tired of swillin on warm rubbery piss-water?

I wanted a way to carry cold water without a hydrating bag sweating and dripping all over me and my backpack.

Got a $10.60 roll of Reflectix, Waterproof aluminum insulating tape, and strip of velcro from Home Depot.

Reflectix is used as house/RV wrap and is essentially a layer bubble wrap sandwiched between sheets of aluminum. I'm not versed in insulating specs but I believe its an R11 rating which is supposedly good for its thickness.

Have an Ogio no-drag pack with the Ogio reservoir. Layed out on the Reflectix fully filled to ballpark a size.

Next taped up the bottom edge and put extra reinforcements in the corner.

Flip it inside out so the tape seam is now on the inside. Double tape the bottom edge again.

Cut the porthole for the drink tube and hanger clip. Reinforce with tape.

Prefold a length of tape to seal up the side seam from the inside.

Press the edges together and double seal the outside edge and reinforce the corner.

Apply velcro so the top has a double roll as an air barrier.

I filled the bag with ice and water last night at around 9PM. Brought it to work today to see how it would fare. Its 6:30 and there is still ice, though most of the bulk has melted.

Cheers!
