Dry Seamless Down Hugger 900 #5

Montbell ‘Hugger’ series mummy bags incorporates elastic-banding into their bags to tight/loosen the dead airspace as necessary. I can sit-upright and cross-legged in my mummy bag.

I have a Montbell that has served me very well. It is about 20 years old. It cost me a whole paycheck when I bought it. I know nothing of their current production, but the lesson is "buy once, cry once". I am looking to upgrade to a feathered friends in the not too distant future.

There are lighter options but your comment didn’t mention the weight, just that you think it is a gimmick. However, I have owned a few of the lighter options (and significantly heavier options) and nothing has been as comfortable and draft free for me as the ZenBivy. It really is a clever sleep system.

I had a Nemo sleeping bag, a Montbell, and a Sierra Designs sleeping bag (I still own the SD bag- if I need a bag, it’s my favorite sleeping bag ever). Those were all heavier than my ZenBivy. As a lighter option, I had an Enlightened Equipment quilt. And you are right, without the sheet, the ZenBivy is essentially the same as the EE quilt. However, with the sheet, it IS very different from other quilts! It is substantially more comfortable and draft free than any other quilt. The system is every bit as good a advertised. I was skeptical… but then I bought one.

I‘m well aware that the Timmermade is lighter than my ZenBivy. Like I said, I have coveted a Wren bag for a long time. However, it costs $200 more than I paid for the ZenBivy! Also, Michael (who started ZenBivy) is a genuine guy too. He is also selling to genuine customers (like me). I didn’t buy one because of any marketing. As I said in an earlier reply, my favorite bag (when I need a bag), is my Sierra Designs Zissou. I wanted to buy one for my son, but they no longer make that bag. Additional research led to finding out that Michael designed that bag for SD, and that he left to start ZenBivy. Which led me to their website. If you don‘t want their products, don’t buy them. But it seems like you are bashing them without even having tried one. They are a good product. Having options is a good thing for our hobby.

What temperature range do you expect when you backpack? Dry weather, humidity, or lots of rain? Are you male or female? Do you sleep warm or cold? Are you a back sleeper, side sleeper, or do you move around a lot? All of these factors come into play for picking a sleeping bag. I'm in Northern California and am a 3 season backpacker. I don't need a 15 degree bag for my trips. It's mostly dry where I go, so I can use down. I'm male and sleep warm, so I can live with a 30-35 degree bag the majority of the time. I have a warmer bag for those rate trips where I need it. I'm a very active sleeper so I went with a Montbell sleeping bag with lots of give. I would also consider a quilt. If you're anywhere near an REI, you might want to go in and get advice.

Me too! I freaking loved Mont Bell gear. I think it's only in Japan now.
