Absolute Lightest 1L Water Bottle

I can't see the need to get much lighter than a wide-mouthed 1L Aqua Fina (or Mtn. Dew) bottle.

YMMV, I used to use cheap and light, semi-rigid supermarket water bottles. Twice, these things would suddenly jump out and escape into the deep ravines below!

For me, I prefer Platy's. They don't try to escape.

I just cup my hands and keep my water there, saving the 21 grams of the water bottle. Of course, steep climbs and descents are a bit tricky……

The lightest water containment device would probably be a homemade cuben one. You could tear/cut the nozzle/opening out of a Platypus and bond that into a homemade bonded cuben sack. You could probably do a 1L cuben platypus for around 10g.

The downside is that you'd need to be very careful with not puncturing it.

I don't know if Cuben would appropriate be for potable use. I think it's high time someone figured out a way to make a Ti foil platy-style bottle that can be used for boiling water in an open fire. It should be ~15g. I may try to make one using food grade silicone adhesive sealant, but welding would be lighter, more durable, and allow for the cooking in a fire. The silicone would definitely suffice for boiling in, but not direct flame.

I saw something almost identical to what you describe on another board awhile back…I think there was a youtube vid accompanying it.

Good tip on the UL recycled bottle.

How about the lightest wide mouth bottle for a Steripen? So far, the Nalgene soft canteen does the trick at 2.3oz each. I haven't weighed a Gatorade bottle yet.

Gatoraide bottles are 1.8oz each.

Maybe the one you had in mind was the steel pot seen here :

not that I think it is practical nor that it will last but there it is…

Man not me, I'll spend 10 minutes shaving a gram off of anything. Eh, to each his own.

I use a 1L Dr. Pepper wide mouth. It comes in at 1.5 oz. I always wonder how durable the lighter aqua fina bottles are.

Dale, I did beta testing for Steripen's new Opti last year on the JMT. I got approved to use the Ziploc 1 qt twist-n-loc container, weighs 1.8 oz. Worked just great.

Makes a good shake container too as one can easily get their 10" square chaomois inside it to clean it afterwards.

it seems like for the steripen users, having a regular bottle with the top cut off would be the lightest option for treating the water. Then just pour into whatever you drink from. With the top rim and cap, most of those bottles are less than an ounce…and the top/cap are the heaviest parts. Seems like you could manage a receptacle to treat in for around a half ounce or so. Only drawback would be the room it takes up.

Food for thought at least?

This is exactly what I do. Took a 2L platy, cut it off a bit above the 1L line, and use that as my treatment container. Weighs nothing, takes up very little space.

2L platy cut over the 1L line, and a small square of bandana to prefilter water into my bottle of choice. Bandana goes inside platy bottom and flatened platy bottom is wrapped around the steripen and held in place with a rubber band. Provides a small amount of protection to the steripen with minimal added bulk.

This last hike I used a 1 quart gatorade bottle and a 1 quart wide mouth collasible nalgene. Very light weight. I treated the water in the nalgene and the transferred it to the gatorade bottle. Then if I needed to carry extra water I treated the full nalgene. Worked well.Doesn't make sense to me to cut a bottle just for purifying. Kind of seems like wasted weight when one can use the light collaspible bottle.

Instead of cuben, try a mylar potato chip bag with the platypus nozzle glued in. That would be a neat project.

I used to use a widemouth nalgene as my sterilizing container, but it never really worked well for me — sometimes hard to fill in shallow streams, my fat fingers never fit comfortably with the steripen into the opening, could never really get a good stir.

with the open top half platy, stirring is easy and I can fill it in the shallowest of streams. The negligible extra weight is far outweighed by the convenience and ease of use for me!

Nice idea. I feel bad butchering a perfectly good platypus, but I'm going to give it a shot in the next week or so.

I was cooking and pulled the mayonnaise out of the frig and the light bulb went on– the mayo was in a 32oz PET container with a BIG lid. After cleaning it out and removing the label, I have a 32oz/948ml water bottle that weighs 1.6oz/45g. My Steripen can do a dance in an opening that big :)

The particular brand is Smart Balance.

What about the mylar insert in wine boxes?

Great minds run in the same channel, Dale. I'm fooling around with a 16 oz version this year, weighs 1.2 oz. I can't remember the brand offhand, but there are several of them in the mayonnaise section at my market. Basically, you could make your selection based on the color of the lid or whether there's a hot chick in a bikini on the label.
