....as soon as you need it you have to empty the contents and start putting them in pockets.
For years I've kept most little things in my nalgene kit in a baggie. Nowadays it's migrated to an aloksak bag. I seem to access it all the time, for gear repair, minor first aid, etc. If I need to use it to hold water, I have everything already in a waterproof bag to throw in a pocket.
(Well, mostly waterproof. Over the last couple years that aloksak isn't as proofed with the little things making tiny holes in it. Still good enough to through in a jacket pocket or another dry container.)
I carry that nalgene kit nearly everywhere. It's pretty beat but still in plenty good shape. I like those lexan bottles as general containers. Besides the usual duct tape wrap, I also have a jug sling tied near the neck, for another length of paracord but also a darn convenient lash point.
As an aside, the one time I REALLY could have used that kit, it was strapped in my kayak floating down a river. Shortly after I found this forum, and now carry a pocket kit in the pfd all the time, in addition to the nalgene in the boat.
