    Reliable waterproofing in a lightweight shell.

    The Rab Men's Muztag Jacket offers waterproof protection in a superlight package for summer climbs and alpine adventures. Its three-layer eVent DVStorm fabric provides highly rated protection and breathability, and it's super packable for when the sun pops out. Fully taped seams enhance waterproofing by preventing raindrops and snowflakes from seeping through.

    Rab also equipped the Muztag Jacket with a fully-covered hood that slides over helmets, stays out of sight on belays, and rolls down securely with the hook-and-loop tab. A hem drawcord prevents the Muztag from rolling over your harness, and zippered A-line pockets give easy access with a harness and backpack on.

    Breaths: Good; Water: Meh; Fit: baggy

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: Large
    • Height: 6'5"
    • Weight: 180lbs

    As I do mostly high-aerobic hiking, I wanted to try out the eVent fabric. I've put this through several hundred miles of hiking now. I'm pretty happy with it!

    Upsides: It really does breathe well. The blue color is great. It's pretty lightweight, you don't feel bogged down with it on.

    Downsides: 1) I've had mediocre experience with rain. Less than an hour in light New York fall rain, and the jacket was saturated. 2) If you are tall and skinny, I recommend you go with the Arcteryx Alpha FL as a rough comparable. The Arcteryx piece has a superior cut for me (longer and more trim in the torso, with longer arms).
    The Alpha FL also has much less of the garbage bag feel to it, especially as the jacket gets moist. The Muztag just starts to feel junky as you heat up and the jacket gets moist (from sweat, from rain). The Arcteryx Alpha FL is superior here, as well, in my experience. Comparing Large in both.
    Yes, you may criticize me for getting a Large, and then complaining about short arms. But the body is already cut too large, even in a large. the Arcteryx in large fits me quite well.

    After a solid month of use in the desert of California, I am sill extremely pleased with the performance of the Rab Muztag. It is an excellent shell and great for all conditions! It is exceptionally breathable in precipitation and great for windy days! It is also really impressing me with durability, reliability and comfort.

    Rab & eVent

    At Rab we use eVent waterproof fabrics in some of our core shell products. These products, such as the classic Latok Alpine Jacket, are specifically designed for use in the harshest and wettest environments in the world.

    These fabrics are extremely hard-wearing and durable, however they combine a range of unique technical features which allow for high levels of moisture movement and breathability. With these benefits, you can wear eVent waterproof products for fast moving activities without overheating.

    Rab Muztag Review

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: Large
    • Height: 6'0"
    • Weight: 160lbs

    First off, I would like to disclose that I work with Rab USA, and received this jacket in order to review it. That being said, I'm psyched on the piece, particularly the breathability of the new DVstorm membrane!

    When I received the Rab Muztag Jacket I was hoping I would be adding a very lightweight, but truly protective shell to my arsenal. I had been working with an old eVent shell that did not fit quite right, and was curious about both the Myriad NeoShell or the eVent Muztag, and I am glad I received the Muztag. I was interested to check out the new, supposedly more breathable DVstorm membrane from eVent, and it did not disappoint. The DVstorm is not quite as breathable as a NeoShell membrane, but the added wind and weather protection is worth it for me.

    Testing: I tried to test the Muztag in a wide variety of uses and conditions and used it in Rocky Mountain National Park for some ice and mixed cragging, at the ski resort for a few days of skiing, a few long skins during a day of backcountry skiing, standing around in rough conditions at an event and another few days of ice and mixed climbing around the Front Range. I think I was able to get a great impression of the piece from this testing.

    Breathability: The Muztag is noticeably more breathable than my last eVent shell, and I was surprised on my first day of use when I was able to wear the shell during the entire hike out from Loch Vale in warm conditions, and even kept the jacket on in the car for a bit before realizing it. During a high-intensity uphill skin the Muztag proved a bit too much, but this was expected.

    Weather Protection: While skiing at the resort, the Muztag proved every bit as windproof as the Gore-Pro pants that I was wearing, despite being a lighter and thinner material. Additionally, during a few particularly wet days of ice climbing the shell shed water like a champ.

    Durability: I was nervous of shredding the shell while climbing because of its lightweight face fabric, but after off-widthing and arm-barring in a sharp gneiss crack outside of Golden, CO, I noticed zero abrasion and was sold on the overall durability.

    Noisy: I felt like the material was a bit noisy, as is supposedly common to all eVent shells, and with the hood on it was a bit difficult to hear a partner from a distance.

    I am 6 feet tall and weigh 160 lbs and the Large was the perfect fit for me. The longer arms work great for ice climbing where you spend a large amount of time reaching above your head. The torso is a nice, relatively trim cut that keeps everything feeling streamlined while climbing or skiing. My brother, who is about 5 feet 10 inches and 190 lbs., tried on the large and it was the right fit for him as well.

    The product seems well made and has held up well so far. The Velcro tabs on the cuff are high quality Velcro that look like die cut pieces, meaning they should not unravel over time. The zippers are nice waterproof YKK zippers that run smooth despite the coating.

    Recommended Layering:
    The majority of the time that I used the Muztag I used the Rab Strata Flex as my mid-layer. This worked great because the breathability of the Strata Flex complemented the Muztag well. I think the key here is using a mid-layer that does not detract from the Muztags breathable membrane.

    Rab Muztag Review

    Rab yourself up in this on a windy day!

    • Familiarity: I've used it several times
    • Fit: Runs small
    • Size Bought: medium
    • Height: 6'1"
    • Weight: 180lbs

    First off I would like to give a huge shout out to Rab and for the opportunity to test and review this fine piece of apparel. Now let's get down to business; as far as I can tell, the Rab Muztag is one of the finest shells I have used to date! It utilizes the eVent DVStorm which is just fantastic and delivers protective and breathable results, while still utilizing the ability to vent precipitation to the exterior of it's 3-layer system. It has a great slim fit, typically I wear a large (I'm 6'1" and about 185lbs) but with Rab I fit in a medium perfectly. The pockets are located higher on the jacket so you can still use the pockets while backpacking because they sit above the belt, and the eVent fabric is extremely light with a very durable construction and is very comfortable and flexible. The hood is shaped well with an adjustable brim and several draw cords around the collar, neck and head for full adjustment. The zipper is good and doesn't snag easily. One thing I did notice about the Muztag is that it is light which is great for packing and warm weather but you def need a mid layer in colder weather. One thing that I actually really like about the Muztag is that it requires frequent washing for best performance, eVent pores clog easily but are easy to clean and only need a soap based detergent like Woolite. All in all I highly recommend this shell to anyone looking for an outstandingly light rain/wind jacket that is waterproof and incredibly breathable. Slim fit + durable construction = happy hiking!
