I spotted these a while ago at Going Gear, but I haven't really heard much about them.

For those who haven't seen them or followed the links, imagine a nalgene-diameter polycarb tube, available in 1.5, 3, 4.5, 6" lengths, threaded at each end, with both single and double threaded end caps. They look interesting because I've got a LOT of water bottle carriers that they'll be able to ride in, but they are a bit pricey for my taste to just jump into.

They've also got a bunch of kits at their website. From "yawn" boo-boo first aid kits to a multi-tube kit the made of for parks rangers that actually looks like pretty good start. They mention the Ritter Mk5 by name a few times there but only as a suggest but not as a kit item. The kit components look like a mixed bag of good and indifferent.
