GSI Outdoors Glacier Cup - Stainless Steel

Very packable.

this would work fine as your only vessel

These are great cups, one advantage is that I can use it on my MSR and cook with it! lexan is great but try putting on a stove...big mess.

I got one of these for my wife and myself. We liked them so much that we got them for everyone in my family before our family hiking trip in Idaho. Everyone thought they were great and they were very convenient. Mine DOES fit a 64 oz Nalgene but I've read other reviews that say they don't. Not sure why some match and some don't. Light and one of the most handy items you'll have with you. I did pay more than what STP is offering these cups for and had a hard time locating enough online for everyone in my family. THIS IS A GREAT BUY!!

A bit heavy but the durability and flexibility is more important to me.

I figured it out. This does hold a Nalgene bottle, but not the new bottles. It will hold the HDPE "retro" bottles perfectly. It was not loose but definitely not tight. This is a great buy if you have some of these bottles!

it's nice an all and i'll still use it but the bottle won't fit inside the cup.

This is a great, well built cup. The only problem is that I've seen reviews saying the 1L nalgene fits inside and mine doesn't. I can only get the bottle into the cup to the 6 oz mark on the bottle. I wanted this to be like my old military canteen. Operation Over a traditional "Mechanic Mike's" soda can stove with HEET for fuel, I brought 12 oz of water to a soft boil in just under 6 minutes in 79 deg air temp. The handles transferred no heat and the cup cooled almost instantly once the liquid was poured out. Its a great deal for price! Glad I bought 2.
