The Echo Park 35 quickly became one of my husbands favorite pieces of camp gear. He is someone who moves around a lot while he sleeps, and the extra room compared to a traditional mummy bag made a huge difference. It feels much more like sleeping in your own bed than a typical sleeping bag. The PadLok system kept everything in place throughout the night, and being able to vent the bag when temperatures warmed up was really nice. It was comfortable, cozy, and perfect for our summer Boundary Waters trip. As someone who spends a lot of nights camping every season, comfort matters, and this bag delivers!
I bought this sleeping bag as the lighter weight version of the Hog Park 20° bag. The Echo Park is supposed to be a 35° bag. I was in a tent, on a Cot One, on a 3.5" REI self inflating foam pad, on a Big Agnes Sleeping Giant 1" memory foam pad . I was wearing light weight merino wool top and bottom plus socks and Smartwool beanie. Way too cold! I felt warm to the mat side cold on top! Zipper catches all the time.
As a person who rolls like a rotisserie chicken all night I find the extra room in this bag perfect. Being able to fasten it to my sleeping pad makes it even better. I commonly use it while bikepacking and while it's not the lightest or most compact, it's definitely worth those penalties to get a better night's sleep. It's plenty warm on chilly nights and works as just a quilt on warmer nights.
