Tent recommendation

[mthayr]

Is the Pro with the Dyneema fabric worth the >2x extra cost?

YMMV - for me that was a yes all day long. The lower you can get you shelter system (tent, sleeping pad, quilt/bag) weight, the better off you will be trekking long miles. Lower shelter weight also allows you greater flexibility in other areas (for me, that would be optics) while still keeping overall base weight the same.

Also does anyone know about trade offs with caring for Dyneema fabric for longevity?

Fold, don't stuff... that's about it.

I am planning a backcountry elk hunt 3rd week of Sept in CO and we may be covering 10 miles a day and sleeping around 10,000 ft elevation.
