I have a small list of things I have been meaning to modify or make, and I knocked out these two yesterday.
First up we have a roughly 1L gatorade bottle.
Just a regular bottle, but I superglued some Triptease so that I won't lose the cap, and it also makes a nice loop when closed so that I can attach it to my pack or a tree or whatever. I plan to start carrying two of these as my sole water storage.
Next up is a freezer bag cozy.
Made this out of a bubble wrap mailer I got at Target for around $1. I used duct tape I already had to seal it up on the edges that I trimmed down. It is sized to fit snuggly around a quart sized freezer bag. I also added some small pieces of velcro tape I had laying around to allow me to keep the cozy closed easily.
I have not had a chance to weigh either items, but the gatorade bottle is as light as it would be without the rope, as I used less than a foot of the triptease. The cozy is light as a feather.
Need to modify my GoLite Jam next, and I want to make some gaiters if I can figure out the fabric.
