New posts forthcoming; back from the road and refreshed from a weekend of ruck walking and refit.
In the meantime, watch the below post from Ivarr Bergmann’s survival series and take note of the clever way he’s made his collapsible 2 quart canteen NBC cap into a make shift hydration bladder. It looks as if he’s taken a drinking tube attachment from the M17 or M40 gas mask series and modified it to fit a hydration bladder drink tube. Taking his example, I did a modified version and performed surgery on a couple of NBC canteen caps and fitted a portion of the drink tube through the cap to the bottom of the canteen, and then silicon sealed the tube into the lid. Not quick as his seems to be for switching canteens, but just as effective for drinking out of a collapsible canteen. It can be used on any rigid or collapsible US surplus canteen that’s plastic. I don’t recommend trying it on the old steel canteens. Anyway, check this out. If you’ve not seen his videos, you may want to get on his channel on youtube. You may get some ideas to help your own kit preparation. This guy tests all his gear while pulling patrols out in the Alaskan wilderness.
