Hey,

The headlamp has 3 - AAA Alkaline Duracell batteries in it if I remember correctly.

I have never tried Princeton Tech lights, I will check them out.

All the items that are listed with the AMK Bivy Pouch fit tightly in the expanded pouch itself, the filled pouch then fits in the cut-off SS water bottle/pot.

The bug dope is for non-winter use, but blackflies are common here from early May till late October depending on the temperature. The combination of cold open water and insects is quite normal here.

Thanks,

Mike
