Mammut Broad Peak PRO vs. Arcteryx Cerium vs. Mammut Eigerjoch Advanced IN

Its time for me to get a new down jacket. I have a northface thermoball and I am looking for something a little heavier but not a full fledged parka. I do a lot of outdoor climbing/camping and I live in TN so I am willing to pay top dollar for a piece of gear I will utilize in the mountains. I have narrowed it down to the Mammut Broad Peak PRO (2018), Mammut Eigerjoch Advanced IN hoody (2018) or the Arcteryx Cerium LT Hoody (2018). All of these look comparable as far as statistics, and Im sure a top brand will make a killer product. But I didn't know if anybody has any specific hit or misses about these products, particularly Mammut....as I can not find a lot of information about those jackets.

I have never worn the Mammut, but you simply cannot go wrong with the Arc'teryx brand. Solid performing, good looking stuff.

Feathered Friends makes an outstanding down parka if you want high end...

Mammut makes great stuff, especially their Eiger Extreme line, however, I think they're drastically overpriced for the quality.  Nowhere near Arc'teryx's craftsmanship.  That being said, I'd give Rab a look before you buy anything.  Aside from Feathered Friends, I think Rab makes some of the best down jackets available for mountain use.

I'll second what those folks said towards arcteryx, FF, and Rab. Outdoor Gear Lab has done some great cross comparisons. If you're wanting to stay insulated during movement, I'd recommend soft shells vs puffy. Atom lt from Arc, Xenon R from Rab. Couple either with an Arc Squamish, OR Ferrosi or Pat Houdini for wind stoppage and you're golden. Need more warmth? Add a Pat R1 under. Better to have layering options vs reliant on one item. Hope that helps. And towards the link I sent earlier, found it ironically coincidental is all

Take a look at Mountain Equipment. Their jackets are on par with Arc’teryx and Rab.

If you're talking active insulation, I haven't found anything that beats Patagonia's Nano-Air Light Hoody.  40 g/m2 of FullRange active insulation, coupled with a Squamish Hoody, Ferrosi or an Alpha FL in real shitty weather, is hard to beat.  I live in the northeast where winters routinely plummet to 0ºF and below.  How cold does Tennessee really get?

I purchased a new down jacket last season and was between Mammut broad peak pro, Arcteryx cerium LT hoody, and Rab electron and ended up going for the Rab. The cut was better for me (less boxy than the Mammut and a little longer than the Arcteryx). I've got a few pieces from Rab and personally I think they meet or exceed Arcteryx.

It really doesn’t get that cold here. Winters are usually teens and on the occasion single digits but most of the time is teens. I’m wanting a jacket that is more of an outer wear. I like to just throw on a puffy and go do what I need to do. And if it really gets cold I can layer and put a shell over. I had a Columbia puffy that got me through the winter rafting in the Grand Canyon for 23 days. I’m looking for something durable enough to handle 23 days in the GC kind of trips, but also something I can walk around town in. I have a microlight puffy, and I don’t want too large of one like the Arc’teryx Cerium SV that would be too hot for around town. My complaint about Arc’teryx is the cerium seems to be a bit short fitting. Sounds like RAB makes good shit! I need to find a place to try them on 

How does the RAB electron compare to the Cerium LT? My only problem with the cerium is its comes up when  my hands are over the head

I believe the arm length was about the same between the Rab electron and Arcteryx cerium lt. The body on the Arcteryx was slightly wider - I'd describe the Rab as a more slim-fitting jacket. The electron is also a bit longer; the Arcteryx was around regular shirt length  while the electron is maybe like an inch or so longer in front and a little longer tail in the back. The hood is helmet compatible but not massive (ie works totally fine without a helmet too). I'm not sure the specific fill power and amount of down in the Arcteryx, but the electron has been more than sufficient for winter trips in Wisconsin, Colorado, Utah, and the Smokys.

@andrew S the reviews I read all say the RAB electron fits pretty large and bulky, and is significantly warmer than the Arc cerium LT because its just a beefier jacket. Good to know you thought it fit slimmer though. Unfortunately, I don't have anywhere to try a RAB on. Maybe Ill look at their return policy and see if I can purchase one and return it if it doesn't fit quite well enough. Im a nerd and part of the fun is researching the stuff before I buy. 

I've never owned the Electron, (even though I wouldn't hesitate) but I do own the Rab Continuum & it's a great jacket.  Very, very warm for its weight, however, the Continuum was designed to save as much weight as possible, so it's a trim fitting jacket meant for climbing.  If you're just planning on wearing this jacket around town and maybe in the backcountry, I'd also take a look at the Rab Valiance Jacket.  170 grams of hydrophobic goose down and a fully-taped, waterproof, Pertex Shield outer shell.  A little heavy at 660 grams total, but it probably nails your checklist.  And no, I have no affiliation with Rab.  I've just used their gear for years and their line fits me well.  Same with Arc'teryx.

I think I have narrowed it down to the Arcteryx Cerium LT and The Rab Electron. I get a pro deal as well so both of these are going to be about half price. @andrew S since you own the Rab...what kind of temps do you think it can handle? Im leaning towards the Cerium because I can probably wear it for sunnier days climbing in the 30s as well as winters around town in the teens or single digits with just a few layers. It seems the Rab would be perfect for winter camping but probably too hot for running around town in the 20s? 

I have a cerium. It's warm and insanely light but not super durable. Better than, e.g. the Ghost Whisperer, but it leaks the occasional feather and I've had some minor tears. The fabric has really good ripstop properties, so holes are tiny and easily covered.

Just an update, thanks to everyone who recommended RAB. I went with the RAB electron and it is perfect in every way. The fit is beyond what I expected and easily the best jacket out there in this mid-level range.
