Men's Kepler™ Jacket is rated 4.1 out of 5 by 15.
Rated 4 out of 5 by from Very good but... I would prefer a few tweaks for downhill skiing Quality, fit, looks, weather proof-ness, durability are all top notch. I have never been cold or wet in this when layered appropriately. I use this 100% for downhill skiing (about 30 days with this coat so far), yet this shell is marketed for winter sports in general- so take my comments with grains of salt. Might be perfect for other sports, or maybe its like all-mountain skis - good for all, not greatest for any. My skiing reservation is solely with the hood and face protection when its zipped up all the way. 1) The hood is "helmet compatible" but its very awkward to wear over or under my top of the line Giro ski helmet. Maybe all shell hoods are goofy this way now days...? 2) I wish the collar went higher on my face when it is zipped up all the way so that I could hide more of my face from the cold when on the chairlift. This one only goes to about my chin. Yes... neck gators and balaclavas were made to address this gap... Summary: I will buy MHW shells again, but I would check their alternative shells more carefully to see if there were a better choice for skiing.

Rated 4 out of 5 by from Overall good shell So far I've been really pleased with this jacket, with only a few drawbacks. The fit is great (I'm 6'0", 170 lbs) with just enough room to throw a midlayer on under it, but slim enough to toss a puffy over it for belays or to look good around town. Haven't been rained on yet, but it kept me warm ice climbing in ouray and biking to work in 30-degree temps with a light baselayer underneath. Only three notable drawbacks--the inside face of the pockets is mesh, not nylon or fleece, so I've found that my hands get cold in the pockets when air seeps up under the hem.Also, the chest pocket is a little too small for my wallet to fit comfortably when wearing around town. Last note is that while I really like the neoprene cuff lining, the inserts are too short for me to be able to comfortably use the thumbholes.

Rated 4 out of 5 by from Light and Functional I would highly recommend this product. I am a climber/skier/mountaineer and got this jacket as a work jacket-of-all-trades. It's very light with a little bit of fleece lining. I would not want to wear this in freezing weather without something on underneath. Seems breathable and it is very waterproof. Fit's very slim, especially in the sleeves, with plenty of room in the trunk for extra layers. I'd buy it again.

Rated 4 out of 5 by from a universal jacket this is a good jacket… I'm not a climber, but spend as many days in the back country chasing trout and steelhead. I wade in Norcal winter rain in this jacket and it keeps me 100% dry. i have hiked through eastern sierra thunderstorms and stayed cool (sweat-free) and dry. This is a universal jacket! i would like to see the "Butter Jersey" cuffs become a neoprene material…

Rated 5 out of 5 by from first shell ever Well I have had two of these jackets thus far the first one suffered a zipper issue in the first month,sent it back for new one, now I noticed some material flaking off the sleeve about the size of a dime,dont know why as of yet but I just sent in a email about this issue and I am gonna send this one in for repairs or a new one.All in all its a great jacket feels great and its wind proof and water proofing are a perfect five this jacket is used over my new Ghost Whisper along with a wool base liner when wet and cold weather are anounced.Will post on how the company responds and deals with this new issue with the jacket.

Rated 5 out of 5 by from As expected from MHW Lots of strange reviews of this around - some say long arms, some short. Tight in the armpits, really boxy cut. Softshell or hardshell.... I'm 5'11'' - 98kg with a solid build...this is the perfect cut for me, i have big arms and it fits well everywhere, i'd say it's fit is slightly large (as i toggle between L and XL on most brands)....but if you've had MHW before in a L, this will fit the same....a brilliant piece that i use for everything....a bit heavier than my old MHW Berrillym Pro shell, but so much more breathable. Hardshell (nylon) with a soft touch....really great jacket, highly recommended.

Rated 3 out of 5 by from Nice jacket but short of great The good: DryQ fabric does breathe very well and is waterproof Brushed (fuzzy) interior is nice against skin, adds some warmth Alpine cut is slim and mobile Butter cuffs are comfortable High quality feel, fabric is soft, quiet. The bad: Pockets are EXACTLY where a pack waistbelt sits and are not "high cut" as described. Hood is OK, but when put over a helmet, the neck of jacket falls under the chin, with no space for a neck gaiter leaving the chin exposed. Not very good for cold mountain days. Butter cuffs thumb loops are non-functional - the cuffs aren't long enough to allow them to be used Brushed interior doesn't slide over fleece very well. And the slim cut makes it a very snug fit with an R2 thickness fleece underneath. Overall: not for super-cold weather due to hood and neck problems. Not for BC skiing due to waist belt problem. Nice for medium cold to mild weather. Fix the butter cuffs, and a little more height to the hood and neck, and move the pockets to a true "high cut" position and it's a winner.

Rated 4 out of 5 by from Rain Jacket The jacket is great. Being a tiny bit heavier than just a shell, it is perfect for those rainy days here in southern CA. Been through a couple storms and sheds water like a duck.

Rated 4 out of 5 by from Amazing quality and design... still not sure if I will keep it This is a really hard review to write. Full disclosure: I have yet to wear this for it's intended purpose (skiing, ice climbing, etc) but I know just based on the construction and holding it in my hands it will be totally BOMB PROOF. When you order it form the site, it's categorized as hard shell yet is described as soft shell. At first I thought it was a typo, but there is actually no better way to classify this thing. You need to feel it to believe it yourself. So why might I not keep it? The fit is extremely aggravating. The entire jacket except for the mid-section is absolutely perfect. I am 5'11" and 190lbs. Athletic build, but not skinny. I generally fluctuate between a large and medium depending on the Brand and function. I bought the Ghost Whisperer along with this jacket to be used in conjunction for my winter activities. For the most part, the GW (size medium) is perfect. The Kepler though is just plain frustrating... I ordered the large, because of some other reviews, plus I knew I would have a couple layers underneath it. If it weren't for the mid-section of this jacket I think I would have nailed the fit perfectly. Unfortunately, it feels like I need to gain an extra 25lbs in the stomach area to make this thing fit... Why not get a medium??? I'm afraid that the medium will restrict my arms, shoulders, arm pits and back too much. These areas are perfect in large. I ordered this online, so I'm struggling with what to do next. I may try to find a local store to try on the medium but it would be sweet if MH would do free returns to account for things like this. I want to give this jacket a 1,000,000 out of 1,000,000 but the size thing is really throwing me off... If you can find a size that fits, BUY IT.

Rated 4 out of 5 by from Great Shell The Kepler shell is fantastic. It has a streamlined fit that I appreciate as a climber, fitting nicely under a harness. The hood is spacious, fitting very well over a helmet. The DryQ fabric is exceptionally waterproof, and seems very breathable, certainly more so than any gore-tex shell I have used in the past. The fitting in the arms, the forearms in particular, is snug. I may have larger than normal forearms, but not abnormal for a fit climber. Over top of a couple of layers the forearms feel snug, and when reaching well overhead (think high ice axe placement) they pull quite tight and therefore pull the tail of the jacket out from under my harness. Although described as a softshell, and having the feel of a softshell, the Kepler is not "stretchy" at all. It's not a deal breaker for anything up to WI5, but this won't be my mixed climbing jacket... I have a MHW softshell that will pull that duty, as it's far more flexible. All in all, this is a fantastic jacket.
