REI Bug Hut alternatives?

This is very similar in an ultralight fashion.

Actually that is not what I was looking for. Looking for something that does not use stakes or some top loop to be effective. But thank you.

Check out the A-16 Bug bivy.

It provides about the same head room as the REI or Simblissity without the fussy set up of either. Basically, you just pull it out of the stuff sack and it pops into place. It’s much lighter than the REI and only slightly heavier than the Simblissity. The only down side is that it packs into a 15″ circle which may not fit into some packs. But I’ve packed it inside my Vapor Trail and MS Ghost without a problem.

That looks great. Thanks. Does it have a floor because it looks like it has something as such? How long is it?

I could use by pack liner trash bag for the bottom end and then probably drape a poncho/tarp over top to keep the rain off if need be. This might work indeed.

Brett, there is 18" of mesh "floor" at the head of the A-16, so you would need to use a full length ground sheet with it. But the weight of a polycryo or shrink film window insulation sheet is only about 1.5 oz., so it wouldn't add too much weight to your kit. Think carefully about sticking the foot of your bag into a plastic sack, though. You could end up with a soaked sleeping bag from condensation.
