Klymit Double Diamond Kinetic Vestimages/KlymitLike something you would see in a James Cameron sci-fi megahit, The Klymit Double Diamond Kinteic Vest will make you stupidly gawk for a few extra seconds the first time it's seen.

The Kinetic Vest does look strangely different – almost like a chic vest that a wannabe outdoorsman would wear to garner attention. The Kinetic Vest shows its more function than a trendy new fashion look.

The Klymit Kinetic Vest is a different type of mid layer. Natural and synthetic fabrics and materials are traditionally used to insulate. The insulator for the Klymit Kinetic Vest cannot be seen or felt – or even smelled.

Klymit uses argon gas as the insulator. Argon, a noble gas, is around us making up less than one percent of the atmosphere. Argon is denser than air and is considered the cheapest inert gas which makes it an intelligent choice by Klymit to use.

Klymit calls their insulation system NobleTek, and it works by trapping argon gas in numerous air-tight chambers in the Kinetic Vest. Klymit claims a 4mm layer of argon has the same thermal conductivity as 14mm of the best synthetic or natural insulators. The company also boasts the Kinetic Vest to be windproof and have superior loft retention.

The Kinetic Vest fills with argon at the inflation port in the left-side pocket. The Kinetic Vest comes with a Klymitizer used to feed argon into the vest. A special canister (7.5 grams) connects to the Klymitizer to feed argon gas into the vest. The argon canisters are sold separately (3 pack $23.95).

The Kinetic Vest does meet the high standard that Klymit claims. The vest is form fitting and does not impede movements when skiing, hiking or any other outdoor activities. The Kinetic Vest has a minimalist design. A pocket on each side of the vest are not roomy but are sized to carry essentials.

The Klymitizer is simple to use in inflating the Kinetic Vest with argon. And the release valve on the left chest area is even easier to operate in releasing excessive argon.

Paired with a light shell or pullover, the Klymit Kinetic Vest keeps and holds warmth for preseason skiing. And it can hold up to the extreme conditions with a technical top layer felt during prime riding season later in the winter.

One of the biggest pluses is the versatility the vest has in adjusting the amount of argon gas inflating it. When the midday sun is hanging high, you can release some or all the argon, so you are not overheated. If the sun has set and the temperature drops, you can easily shoot more argon into it to increase the insulation.

What is a Noble Gas

According to

A group of chemical elements with very similar properties: under standard conditions, they are all odorless, colorless, monatomic gases, with a very low chemical reactivity. The six noble gases that occur naturally are helium, neon, argon, krypton, xenon, and the radioactive radon.

The vest is breathable. The air pockets that trap argon gas allow for moisture to escape although keeping the loft intact. The breathability is surprising considering the technology and design of the Kinetic Vest.

The upkeep of buying additional argon canisters is a minus to the Klymit Kinetic Vest. It's an expense that can add up if the canisters are frivolously used. Klymit says a fully inflated vest can last up to three months before all the argon gas dissipates. And each canister can last two to six fill-ups depending on the vest's size.

Traveling with the vest can become a problem. Heightened security measures at airports require that the Klymit Kinetic Vest be packed in your checked luggage and not in a carryon. Argon is an inert gas and is completely safe. But an uneducated TSA agent may not realize it and try to confiscate the vest.

Klymit LogoThe Klymit Kinetic Vest is an innovative mid layer that creates warmth and is breathable. The use of argon is unconventional and an advancement and technology in outdoor gear. Argon is ecofriendly insulator. It doesn't pollute the environment and will never take up space in a landfill like traditional insulators.

The Klymit Double Diamond Kinetic Vest has a suggested retail price of $224.95. The Double Diamond model is designed primarily for snowsports. Klymit offers additional Kinetic Vest models designed for other outdoor activities.
