Bought a Zeus last year in the fall and it quickly became my go to jacket during the winter. Very lightweight, but the fabric seems pretty durable - had a couple of run ins with tree branches but the fabric stayed intact. I bought a large and it has plenty of room for a good midlayer for extra warmth. Inside pockets are generous and large enough to hold a 32 oz water bottle or other items. One thing Marmot could do in the future is use a different fabric, like a microfleece, for the collar on the inside as the neck gets pretty cold if the fabric touches you.
"Great Puffy, but Wish it had a Chest Pocket"
This is an amazing jacket! I have had it for two years now and have had no problems with it. It is totally down proof. I have never had any down poke through, like some of the jackets I have had do. It is also light and durable. I know those words cannot often be associated with the same product, but I think they both apply for the Zeus. I wear this jacket all the time, almost everyday during the winter and it still looks almost brand new. I have hiked through thorn patches with it and they do not penetrate the tight weave of the outer fabric. My only gripe is that is does not have a chest pocket, but I knew that when I bought it.
I recently won this jacket in Moosejaws 20 days of giveaways. This is the lightest and warmest winter coat I have ever had. It's not really a coat but I'll be wearing it as one. I used it sledding with my kids and no snow got in. I love that it zips up to my jaw line to keep the weather out. I put it on New Years morning for my first hike of the year and again, it was only 15 degrees outside and I didn't feel any cold at all. This is a great coat and I would highly recoommend it to anyone who is a Hiker out on the trails on those cold blustery mornings
"Comfortable, Light-weight, and Overall Amazing Down Jacket"
This is my first down jacket as I've avoided colder temperatures for most of my adult life. However, winter in Afghanistan and a scheduled trip to Kilimanjaro in March convinced me to spend the money on this particular jacket. This thing keeps me very warm, weighs practically nothing, and, best of all, packs tightly into one of its own pockets. Since I travel a lot, the ability to compact this warm jacket into a small square and stuff it into my pack is absolutely fantastic. At 6' and 170lbs, the medium fits me quite comfortably across the chest and core, but the upper sleeves are a bit too puffy/wide--there's a lot of room in those sleeves.
This puffy is by far the warmest thing around. I've used it while backpacking in the Smokies, Pisgah National Forest, and in Norway for the last 2 years, and could not be happier. IT kept me warm in -20 degree temps while exploring the fjords, but it should definitely be used with a rainshell if you want the down to keep its loft. It's a great purchase, and will keep you snuggly all winter long.
