Well built, good thick canvas, good zippers, solid guy ropes and pegs.
They are top opening, so you'll get water inside when you open the zip to get in/out. if there is a decent dew or rain.
Bulky with the foam mattress inside, too big to tramp with, even without the mattress.
No room for pack, rifle, boots etc inside, barely room for a change of clothes, not that you could get changed inside the swag.
Warm, dark, and mildly claustrophobic especially if you were a bit bigger. (I'm not.)
I use mine when camping with my wagon so I can sling a tarp over it.
They get a yes from me.
