I have a Megalite bag - regular length - and love it.

But even at 66 I'm not ready to tarp it. That's why I use a TT Moment tent at 28 oz. W/ 2 stakes.

And I use an old Thermarest Lite, regular B/C I demand 8 hours of sleeping comfort. At 16 oz. it's "barely" heavy but comfortable. Had a regular Neo-Air and did not like it for several reasons so I ret'd. it to REI.

My pack weight (REI UL 60) W/ 6 days food and 2.5 L. of H2O is 28 lbs. Good enuf fer me.
