Yes indeed. The Catalyst worked for me in Colorado last year. You can compress the Catalyst. You can't expand smaller packs.
Platypus 2 liter Hoser x ONE is plenty on the East Coast. Supplement with an empty SmartWater, etc. bottle if needed.
Why are you pleased with your weight?
I'm your height and my trail weight last September was 145 pounds.
Drop a hundred pounds.
Good luck.
