OK - now I see what you mean. But I think you've got some engineering and testing ahead!

Here's the Wiggy's rig

Wiggy's SS Bottle

Looks like they've improved the dongle on the lid since I bought mine.

The Wiggy's rig looks good (as does the water bottle that started this thread).

I'm really concerned about the weight of these items, though.

It's not a problem with car camping, short-haul trips or BOBs.

But with self-propelled trips, either day hikes or multi-day backpacks, where you are carrying your gear on your back, you consistently leave too-heavy items at home. There's an equation of weight-vs.-utility that you work through. And IMHO, both of these items would stay at home (for this kind of trip anyway).

However, the future is not bleak. I see more and more stainless steel items that are quite thin and light, yet reasonably tough. These promise to be a boon for unrepentant walkers such as myself.

Oh, wow, I think I see where you are going. Like a the cheapie travel mugs that have the removable bottom so they can be cleaned, but made out of stainless and lacking the handle. Maybe use something like styrofoam or fiberglass insulation in a plastic sheath as your removable inner insulation but that wouldn't be critical.

Have a screw on bottom and a screw on top. Heck, it might be possible to make the bottom wide and deep enough that it could be used as a small bowl or large cup. You'd want to be able to be compatible with the standard Nalgene cap so you can use all the various filters out there. And if it's shiny, it would work great with the Steripen- UV bouncing off the sides rather than going out the bottle.

It wouldn't be a field conversion, but I think you might have something there.

I think I may stick with my nalgenes and space saver cups. I feel the wide-mouth 32 oz/1l nalgene bottles are about as small a mouth as I'd like when it comes to bottles in regular use. I use mine for far more than just for water and can't imagine being able to really clean smaller-mouthed bottles well with any certainty. Bottles are notoriously hard to clean anyway.

I EDC drinks in these bottles with an Outdoor Research (OR) Water Bottle Parka® 1 Liter that zips shut over them. This insulation works so well I carry these bottles year-round. I have stainless steel space saver cups for all my bottles in various packouts. While I would prefer the spacesaver cups run about 2/3 the height of the bottles (adding about 1 extra inch) instead of the 1/2 reach they have, I'm still happier with these setups as they lend towards maximum flexibility.

BTW, the space saver cups also easily fit within the OR bottle parkas with the bottle...similar to the old military canteens and the steel cup.

Ok, I got it in the mail last night, the company had been snowed out and sent me a few extra items for the wait . Here's what I have so far:
It's a thick 32 oz stainless steel bottle and appears very durable with a lifetime warranty. It does boil water and fits a normal 32 oz lid including water filters and steripen. It takes awhile to bring up to a boil because I think of the thickness of the steel and convection of sitting in free air.It has a small groove on the inside of the neck that corresponds to the flange and doesn't appear to pose a problem for future cracks or anything, I think its from a weld joint and is normal, if anything it would act as an expansion joint.I don't know how it would do in the cold yet but I think if you get it right in a good fire you will be ok. It's not as bulky as my nalgine cup set up and I tried weighing it but my scale won't go below a half of pound. All in all the pictures below are blurry because I'm in a rush to goto work and it's not an official review but I like it, it serves what I need it to do, Use it with a steripen and a Katadyn combi water filter if needed, boil water in and emergency and can cook or polish the bottom for a mirror if needed. I found after you boil the water,you can dip the outside of the bottle in water and it cools down almost instantly. So the bad side of this is it does transfer heat around quickly but you can manipulate it to your advantage by putting up a wind block from green wood or what have you. I looked at aluminum and it transfers heat even faster and not as durable. I'll stick with the stainless steel anyday. (on the pictures you may have to right click the mouse and say view image)

Update: it is air jacked (see comment below) and I would not recommend it.

Looked a little like an artillery shell at first- kinda concerned me before I started reading *grin*

Looks good. I suppose the only way to know for sure is to stress test it.

My apologies, I dropped the ball. When I did some of this testing it was before work and I couldn't tell if it was a thick canister of jacketed. Like a dummy and in a hurry I was wondering why it took so long to heat up. Well I took it into work to examine more closely and it has what appears to be an air jacket around it. So I'm skeptic that in a fire at lower temperatures if it would get hot enough to boil water, especially in winter. So I would not recommend it for use in this case. If you just want it for a water bottle then it would do at that but that's about it for it. So I guess the search goes on.

Really??!! Sure fooled me. If there's a air jacket, it must be very thin -- you really can't tell by looking at it in the store. An second layer of stainless would explain the weight, though.

I e-mailed back the company asking them why on there website it said single jacket also, so well see what happens. It definitely has a second wall.

I have one of these Guyotdesigns bottles sitting on my desk, and I can't believe this thing is double-walled. Run your finger and thumb like calipers around the opening and the shoulder. When I fill it with cold running water, the sensation is instant cooling on my hand. It just can't be double-walled.
