Thank you Mary!
I'm 46 and I have 'jumped' your age/comfort ratio a bit, I have proudly arrived at the use of my Kooka Bay downmat last year. As with many, I swung to ridiculous minimal weight and then swung back to 'acceptable low, low weight' for superior comfort. It's darn well worth it to me to get a great nights sleep, I can play 'Lucan the Wolf Boy' with my cook set.......;) (obscure 70's reference there.....,)
On this theme I am building a roomy cuben tunnel tent to further identify with Roger(shhhhh, top secret)..... Thank you both for your wisdom, it's hard to come by in today's world.
