Product Description





Garments made with Comfortemp® PCM fabric are less bulky than those made with traditional synthetic insulators and are both fashionable and functional. They can be safely laundered when necessary and do not lose their effectiveness. This garment weighs 16-25 ounces, depending on size. The optional cold pack inserts each weigh 5 ounces.  This vest features soft, nylon Taslon  fabric in your choice of fashionable colors, and is available in sizes XS to 2XL.





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 plus years. By using a two step thermal regulating system, we have achieved comfort at outside temperature, from -20 F to 100F.

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. Creating the perfect outdoor enthusiasts must have gear!



* This vest acts as a heat sponge when in an environment hotter than 83°F. To discharge the heat, simply move or shake the garment to create greater airflow

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.  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. 





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

Perfect For:  Everything!

  • Travelling- Stay cool and comfortable throughout your journey, and use the large zippered pockets to hold all your important travel documents close to you.

  • Hiking
  • Biking
  • Jogging

  1. Excellent 5 Star Review

    Posted by on 3rd Dec 2014

    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.

  2. Best Vest Ever 5 Star Review

    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.
