Product Description

You Asked For Them, We Listened!

Find your comfort zone with a phase-change fabric vest from Zentek.

This vest features soft, nylon Taslon  fabric in your choice of fashionable colors, and is available in sizes XS to XL. The vests are completely lined in the highest quality phase change material available.  If washed and dried cool, we have found this material to last 10 years.Developed by NASA scientists for use in space suits, phase-change technology (PCM) absorbs energy to cool the body when it's hot, then releases the stored energy as heat when the body gets cold.

This vest features two front zippered pockets on each side, plus two more patch pockets, for a symmetrical design. Originally designed for dog trainers,it is now used for traveling, and medical needs. You will always have what you need at hand. A large, convenient pocket on both sides of the  outer shell is divided into one small upper and one large lower compartment. One the left side and above the left pocket are nylon rings for water bottle or leads. A deep dove shelf pocket on the back provides ample storage for a water bottle or other supplies, and is stitched in the center to create two equal compartments.  Inside the mesh/Comfortemp liner, are 3 mesh ockets for cold packs. Two are at the lower front, to cool the femoral artery, and one between the shoulder blades to cool the lungs. This garment weighs 16-25 ounces, depending on size.The cold packs each weigh 5 ounces. By using a two step thermal regulating system, we have acheived comfort at outside temperature, from -20 F to 100F. 

The most common comment we hear is that " I wear the vest all the time" and " They are additive"

Garments made with Comfortemp® PCM fabric are less bulky than those made with traditional synthetic insulators and are both fashionable and funtional. They can be safely laundered when necessary and do not lose their effectiveness for ten years.Zentek garments are completely lined with ComforTemp PCM fabric. This is why they are being used by MS, COPD and cancer  patients for temperature regulation.

Perfect For:

  • Travelling- Stay cool and comfortable throughout your journey, and use the large zippered pockets to hold all your important travel documents close to you.
  • Motorcycle Riding - Wear this vest under your leathers. In the summer an open vent circulates the heat away from your body. In the winter, close the vents on your leathers and trap the heat in close.
  • Hot Flashes - Wear this vest at night to combat the discomfort associated with hot flashes while sleeping.

    Product is excellent, although I could have used some kind of instructions telling me if I needed to do anything to make product ready to use -- if any.

    Best Vest Ever

    (Posted by on 17th Jan 2013)

    This vest keeps me warm and cozy but is so light weight I don't even know I am wearing it. This is the second one I have purchased. They help keep you cool in the summer too.

    Addicted to say the least

    This is the best piece of clothing that I own. It was a gift to me last Christmas from a friend who purchased it at a dog show.... It comes off to be washed and then, back on again. I wear it under jackets and on top of shirts and sweaters. It keeps me warm, and cool!!! There is something about the material that is comforting when I have it on, as though it is "second skin".....hard to describe. Am about to order the second vest...

    Liked more than I thought I would.

    (Posted by on 21st Apr 2011)

    When I bought the vest I thought I would only be wearing during the day. I found I slept better a night with the vest on. I cannot wait to try it in the summer. My dog has had the coat for 3 years It still looks like new. In December I got another coat for my older dog and she just loves it to. I own French Bulldogs and they are hard to fit and keep on. These coats are wonderful for my Frenchies. Thank you

    Love It!!

    (Posted by on 12th Mar 2011)

    I thought that I would let you know how much I love this vest. I bought it at the January Puyallup show. I think I have worn it to work almost everyday since. Originally I bought this vest to help me keep warm at agility class, but soon found myself wearing it to/at work. I tend to be cold all the time, but wearing this has helped me to be more comfortable. I can't wait till summer/fall to try it out for hiking. Thanks a lot.
