Zen bivy vs western mtn versalite

[Coopsdaddy]

I got a zenbivy ultralight 10 degree (goose) a couple months ago and have put a couple weeks on it so far. It’s without question the most comfortable sleeping system I’ve ever used, but needs to be paired with a good pad - I’ve been using the xtherm nxt max. The first night I had it on a neoloft at 30 degrees and got a little cold.. switched to the xtherm and it’s been a lot more comfortable. Coldest I’ve had it to was 25 degrees and I definitely needed my SG puffies to stay comfortable. I find the claims that it’ll be comfortable much lower than that hard to believe, but maybe I’m just a pussy.. That being said, I’d rather sleep in this system than go back to any sleeping bag so I’ll bring a lightweight FF blanket to help when the temps look like they’ll be much colder.

Pretty bad for a 10 degree.You need puffys at 25 in a 10 degree bag.
I realize some sleep hot and some sleep cold but that’s a big difference.
Not sure why these companies can’t have a standard.
Like sleeping with underwear and bra only.
They all measure at different metrics to fudge the weights and pack size.
No way I would pay that for a 10 degree to have to bring along a blanket.
I want a Zen bivy because of all the praise but will definitely have to chat with them on temps.

I used a 10 degree Zenbivy in Colorado last year with no problems. Camped at 11k and temps got into low teens and was fine. No extra puffy or clothes needed.
