    • Zamst ZW-7 Back Brace & ZK-7 Knee Brace

    Zamst ZW-7 Back Brace & ZK-7 Knee Brace

    Zamst ReviewInjury is something no skier ever wants to to deal with, especially the long term repercussions—but it happens. For me it was a zipper crust that caught one ski and proceeded to make a wish with the other. On the loosing end of this game was my MCL, ACL and meniscus in my left knee, which just happened to be my ‘good knee’ as the right one had already had an ACL replacement years earlier. Then, a few years ago I took a 15 foot drop onto a newly created cat track at the local ski resort and that was the start of a life long affair with a compressed disc between L4 and L5 (thats the lower lumbar spine).

    Being what they call ‘middle aged’ (I hate that term) I now have a growing list of skiing related injuries that I am trying to manage so that I can keep on backcountry skiing well into my 80s. When I stumbled upon Zamst Precision Engineered Support products at the 2014 Winter Outdoor Retailer Show in Salt Lake City it was a no-brainer; I asked them to sign me up to test out some of their products. Zamst is a company that produces reinforcement, recovery and protection products and was the brainchild of Nippon Sigmax, a leader in medical orthosis. Zamst has a product line that offers up over 39 support products for part of your body including achilles tendon, ankle, arm, back, calf, elbow, foot, knee, shoulder, thigh, thumb and waist. They sponsor a variety of hard core athletes who champion their products, however I could not find any medically supported testimonials on their web site pertaining to their products success.

    Zamst ZK-7 Knee Brace

    After having surgery a few years back to correct the issues in my left knee I was interested in supporting it while skiing to prevent further injury. The good folks at Zamst sent me a Zamst ZK-7 Knee Brace and I have been wearing it while resort skiing and backcountry skiing about 4 days a week this season. The ZK-7 is said to be the strongest knee support Zamst offers for moderate to severe sprains of the ACL, PCL, MCL and LCL of which I qualify with two of those three injuries.

    The built in ‘Exo-Tech QUAD’ uses resin stays to provide 4-way ligament support with medial and lateral stability (MCL/LCL). The exterior velcro x-straps and parallel interior straps provide stability for anterior and posterior ligaments (ACL/PCL). The ZK-7 also uses ‘i-Fit technology’ which is a semi-open design that allows the braces to fit a wide variety of users and helps prevent the brace from slipping.

    Zamst ZK-7 Knee Brace Review

    Features:

    Exo-TECH (QUAD) - Exoskeletal four-way ligament (ACL/MCL/LCL/ PCL) support with individualized fit and multifunction design.
    Flyweight Tech - Advanced material fabrication with lightweight construction.
    i-Fit - Open panel design with adjustable fasteners provides individualized fit, enhanced comfort and variable compression levels.
    Kneecap Stabilizer - Stabilizes the kneecap while body is in motion
    ROM-Tech - Pre-curved design allows knee to still have full range of motion.
    V-Tech - Ventilated flow through design keeps you cool while in motion.


    Zamst ZW-7 Back Brace

    With two levels of ‘i-Fit’ adjustable velcro compression and the four panel ‘Exo-Grid’ stabilizers, your lumbar stability is looked after. Grip Tech material keeps the ZW-7 in place even over a base layer which is how I ran the ZW-7 due to the high aerobic nature of backcountry skiing and my pack’s hip belt placement. While the ZW-7 is not designed for any specific back issues it does offer up un-impeded support for your lower back while engaged in high aerobic activities (such as backcountry skiing).

    Zamst ZW-7 Back Brace Review

    Features:

    Exo-Grid - Dual stabilizer inserts provide anatomically correct stability.
    Grip-Tech - Anti-migration design prevents slipping during activities.
    i-Fit - Open panel design with adjustable fasteners provides individualized fit, enhanced comfort and variable compression levels.
    ROM-Tech - Pre-curved design allows for full Range of Motion.
    V-Tech - Ventilated flow through design keeps you cool while in motion.


    Verdict:

    If you have any joint injuries that need a little attention and support to get you through your active life then the Zamst line of products is worth taking a look at. I was not sure what to expect from the Zamst ZK-7 Knee Brace and the The Zamst ZW-7 Back Brace but I was pleased with the amount of support that they provided while backcountry skiing as well as skiing laps at the resort. I have been wearing the Zamst ZW-7 Back Brace over my base layer for the past two months while skiing and it has made a world of difference. My lower back muscles are not as fatigued after a hard day out with plenty of vertical gain under my skis. The compression provides support and is said to keep my spine more elongated thus taking pressure off of my compressed disc which allows me to ski longer with less discomfort in my lower back. The Zamst ZK-7 Knee Brace provided similar support and gave me confidence that my knee could hold up to skiing on those less than ideal days that seemed to be plentiful this season. The ZK-7 was soft and comfortable to wear while skiing, however I did find that on the chairlift when my knee was bent the brace did impede blood flow and occasionally I got tingly toes. Thanks to the design and features of the ZK-7 I did not sweat at all and the brace stayed in place perfectly. Similarly the ZW-7 back brace was comfortable and stayed in place thanks in part to the compression but mostly due to the quality materials it is made of. I was expecting to perspire quite a bit under the ZW-7 but to my surprise sweat was limited or nonexistent all together.

    Overall, if nothing else, the Zamst products that I tested kept me aware of my lower back and knee so that I would remember not to go too hard or too big. Going backcountry skiing or resort skiing without them now makes me feel vulnerable to injury as I am used to the added support. I would highly recommend checking out the Zamst products if you are dealing with old injuries or are simply, as they say, ‘middle aged’ and in need of some additional joint support.
