I've had a Solplex a couple years now. Total weight with poles, stakes is 19.5 oz. Sorry, you'll have to convert to grams. Holding up well. Like other ul gear, not gonna cut it to pass on to grandkids. No punctures yet. Much less condensation than silnylon. Not much space inside it, can lay some gear alongside you or just leave the pack in the small vestibule. I do quite a few solo trips.

I special ordered a heavier floor.
