i so wanted this to work

I could think of many. What is the reason you said no purpose?

is that a rubber band?
reflectix could be lighter.

I just envisioned it being a cup to sip hot or cold beverages from but never made use of it….if it did have purpose I'd love to hear it, tea mug? I think I was daydreaming. The weight is nice and an alchy fuel bottle will fit in it.

Ken, unfortunately that is a rubber band…..if I could find silicone at that size it would be nice. I don't think I've tried hard enough. I'm not convinced reflectix would save on weight when given the tape, but I don't argue it would be more efficient.

Fyi, I also had a version of this in 24oz. Fits more stuff inside that's for sure

If you ever wanted any sort of mug on the trail, that would be perfect. I used to carry a 12oz MGD can that would nest inside my heiney pot, and I would use it to drink coffee out of in the mornings.

If you could prevent it from being crushed inside your main pot, it would make for a good coffee cup or in the winter you could make jagermeister snow cones? haha

They also fit nicely on the end of the small (16 oz.) nalgenes.
