Extremely warm for its weight

Rating:****
This jacket seems to be sized too small - compared to several other similar coats, I had to get this one in the next size up. Especially if wearing a fleece layer underneath. Also the length could be a bit longer (I am 6'5" though). The hood tightens from the back - not obvious at first, and does not completely tighten around the neck area. The zipper is a bit awkward to start, especially with gloves on. However, this is a very warm coat overall. Took it hiking in 5 degree weather and had to partially unzip it a few times. Very comfortable and lightweight.

Stratus Hooded Jacket

Rating:****
I got the Stratus to fill in a hole in my jacket quiver, and it fills the hole nicely. The sizing is a bit small, which I anticipated, and the Size L fits my 6'3" 175lb snugly. The sleeves are just barely long enough. The lefty zipper is a bit odd to get used to but works just fine. The one gripe I have is that the handwarmer pockets are entirely outside the insulation making them less good at handwarming.

Portable comforter

Rating:*****
As an insulator it does not get warmer than this, the superb fit retains every bit of body heat and the windproof ability really protects also, wore in extreme weather and was not disappointed. So confident at my comfort level I had my outer hard shell unzipped in twenty degree weather. It is waterproof as claimed so it can be worn alone. Cannot think of any cons besides it my need more pockets, but it serves it's main purpose wonderfully.

Finally

Rating:*****
I have been looking for this microfiber insulated jacket for years. It fits perfectly inside my Mammut Shell. The thumb rings are perfect for making sure gloves/mittens interaction is seamless. Plenty of loft to keep you warm on any cold day. I use as a layer to keep me warm (not dry, that is what shells are for) while skiing or hiking mid winter. I can't say anything negative.

A Must have piece!

Rating:*****
I have used this piece for backcountry skiing at -5f and have skied with it at +2 at the resort. I had to do duty as a starter for a ski race when the temp was hovering around 0 all day and I stayed warm every time. Big water bottle pockets inside and small but useful pockets elsewhere. the hood is not big enough for a ski helmet .

Great for camping or anything

Rating:****
I wear this camping, hiking, and walking the dogs at night when it drops below 30. It fits well under my hardshell. I would give it 5 stars, but I think the storm flap could be sturdier and maybe micro fleece around the chin. Other than that, you can't ask for more in a jacket.

Warm and Toasty

Rating:****
I wear this jacket by itself and under my hard shell. It has proven itself to be very warm. The zipper is sometimes hard to start and undo. The weather guard could be stiffer and the chin lining could be micro fleece. Overall I am very satisfied and would not change my choice.

Solid Overall

Rating:****
On the bulkier side, but warm and effective. The main zipper is a bit difficult to start and it's left handed. The hood tightener doesn't keep the wind out completely. The fit is on the snug side. Love the cut, warmth, and fleece lined pockets.

Wonderful!!!

Rating:*****
Absolutely wonderful. Fits like a charm - European sizing - so smaller than American sizing. Feels very warm and comfortable and completely worth the [$].
collegeMainer at Sierra Trading Post on 10/19/2009

Functional and stylish.

Rating:*****
This jacket is great for just about anything. Perfect "mild winter" jacket, awesome belay jacket, and a great lunch stop jacket while hiking.

Negative Reviews:

very poor hood design

Rating:**
Rather puffy, looks like it would be very warm, has alot more filling than other synthetic jackets. The single pull hood cinch that Mammut uses does not work well on the Stratus jacket,(I have a Mammut Blackburn from STP and the single pull cinch works ok, not great, with it), it does not tighten the hood around the head/face, only pulls the hood back, about eye level, away from the face, really poor design. Otherwise looks like a good jacket. I only say it runs small, as it is ero sized which tend to be made on the trim side. I order all ero clothing a size larger. I returned it due to the hood.

Neutral Reviews:

Stratus has strung

Rating:***
Very warm Jacket. Great for belays. Runs small. I usually take large and I took xxl in the stratus jacket. The reversible zipper is nice, but it is rather hard to get the zippers to align and then in turn zip up. Could have a better zipper system. The zipper slide is on the left hand side rather than on the right. I believe that this reflects European craftsmanship.
