Review K-Way Mercury Shell Jacket

First impressions:

When I received the packet at the post office I was surprised how light and small it was for what is a proper shell jacket.  I was lucky enough to be able to test it quite a bit as we are experiencing a lot of rain lately and I must admit that I’m impressed. It does what it says, it is water and wind proof, and it is comfortable. The comfort is mostly due to the overall light weight, breathable fabric and the comfortable fit. I was immediately impressed by the long sleeves, as I have long arms and it irritates me when jacket and shirt sleeves are not long enough.

The good features:

Review K-Way Men's Mercury Shell Jacket

Sealed seams + the hood has volume and visor control.

As mentioned, it is light, water proof, wind proof and breathable.
I’m quite impressed how breathable the material is.  I walked around in it in sweltering heat and I didn’t feel like I was wearing a black plastic bag.
It’s not just the sleeves that are long enough, the trunk is also long enough, it goes down to below the buttocks which allows the water to run off (and not go down your legs).

The hood is well designed and the drawstrings have little sleeves that keep it out of your face.  It also features a slightly stiffer visor and a Velcro strap at the back to adjust how low the visor sits on your noggin.
Pocket zips are sealed and there’s a little hood for the zipper.  Nothing in my pockets got wet, so I reckon it works rather well.

Pocket zips are sealed and waterproof

*  The main zip is not sealed like the pocket zips but it has a flap that covers it.
*  Double zipper on the main zip.
*  The 2 pockets are big enough and well positioned.
*  There are draw string around the waist, personally I don’t know who would need something like that, but it is there.

*  All the seams on the jacket are sealed.
*  Dries very quickly.
*  Made in South Africa.
*  The logos are all reflective

The bad features:
I can’t find anything wrong with this shell, it really is well made.  I can’t even find any minor stitching issues.





Last thoughts:
I couldn’t really test it in strong wind, since I am based in Pretoria and the wind does come up much at this time of year, but it is pretty obvious that it will handle wind well.  How suitable it will be to use as an outer shell on BIG  mountain expeditions, I don’t know?  But I’m confident it will be able to handle anything our local SA weather can dish up.

As a last resort to wind test the jacket I hung out the car window while my buddy drove the car at 40-50 km/h.  Although it’s not the same type of wind you get on a mountain, the results were good.

Available at:  Cape Union Mart (this jacket can be purchased online)

Price:  R999

    Hi guys,I would really like to know what the real weight is if it will b gud enough for say a trip to the berg or maybe killi? Is a hard or soft shell? Thanks

    Any idea whether it will fit a helmet under the hood?

    Wesley, K-way says it weighs 285g, but I think it depends on the size. Please don’t sue me if I’m wrong, but yes I think it will handle the Berg and Kili – just make sure your other layers are good enough. This is a hard shell.

    Craig, good question, I haven’t thought about it. I’ll test it tonight.

    Craig, yes it works, but it’s not very comfortable. It works much better to put the helmet over the hood. I tested it with Petzl Ecrin and Elios helmets.

    cool, thanks Shorti! sounds like you could make it work if you need to!

    Good review. The hoods at the top of the zippers are key. Sounds like K-Way is upping their game. Thanks Shorti!

    I’ve had a surprisingly disappointing experience with Kway and the company’s customer service. Did you know that their jackets are not 100% waterproof as they declare? According to Matt Feigin, the president of Kway, there are many definitions of waterproof and much confusion around what waterproof means. Apparently a “100% waterproof” jacket by Kway isn’t waterproof if you walk in moderate rain for 12 minutes. It confused the president of Kway that someone would buy waterproof jackets and think that their shoulders wouldn’t be drenched after a 12 minute walk in some rain.

    Here’s the response I got when I told Kway in an email that I was disappointed with my purchase of buying rain jackets for my entire family and would there be any way to resolve my problem:

    Hi kathy,

    I am very sorry to hear that you had a bad kway experience. The term waterproof is commonly confused. There are many different types of waterproofing and many different levels of waterproof. The classic jacket is treated with 1500 mm’s of water proofing. That means that in a 24hour period only 1500 mm of water can fall on the jacket before it starts seeping through the jacket.

    Unfortunately there is nothing that we can do for this matter. We can however suggest you a more waterproof jacket and offer you a nice discount on that product.

    Thank you in advanced for understanding.
