Try as I might I am just not a bivy camper. I will let these both go at a loss with only 2 nights use on the Superlight and 1 night on the bug bivy. Both look to be in brand new condition. No issues with either bivy.

MLD Superlight Bivy XL 8.9 ounces on my scale in stuff sack with all cords and line on it. Stuff sack is .5 ounce. Full net hood option. FS:$185

I am 6'1 240lbs and it slept me with a Neo air and 30 degree quilt fine.
MLD Bug Bivy with Green sil floor. 7.9 ounces on my scale in stuff sacks with all cords and line on it. Stuff sack is .4 ounce.
FS:$115

(FULL DISCLOSURE) This bivy slept my 65 lb lab with a pad down in the floor. He did well with it, and I shook it out so the hair is gone. He is a well kept dog and it was a dry trip. I only mention it if someone had an allergy (I have a cat allergy) and though I didn't expect him to hurt it I checked it over and it appears to be in perfect condition.

Check out my dog if that is an issue.

Will sell the together for $290
