I used this bivy (6’ version) with a Hyperlite Mountain Gear tarp while bikepacking the Colorado Trail last summer. It rained almost every day, so knowing I had this cozy space to retreat to at the end of the day was always fantastic.
Pros: light weight, breaths well, no condensation, plenty of space inside to move around (I’m 5’11 & broad shoulders), durable, versatile (can use it to cowboy camp or under a tarp), set up is quick and easy.
Cons: The material on the bottom is very slippery on my ground sheet (I’m looking to add some silicon dots to the fabric to reduce it sliding on my ground sheet.
All in all this Bivy with a tarp is the best shelter I’ve ever used. I hiked the PCT in 18’ (did not use this shelter system) and no doubt will be using this on my next thru hike or any outdoor adventures.
