Rab Kaon Jacket Review


The Rab Kaon Jacket is made from 800-fill power European hydrophobic down. The advantage of this type of down is that it won’t get wet as quickly as standard down, which will eventually become saturated in the rain and stop keeping you warm. Rab uses this type of down along with synthetic Stratos insulation, which is placed in high wear points, such as the hips. This combination allows Rab to use all of the down’s weight.

The Kaon uses 800-fill power European Hydrophobic Down, which doesn’t wet out as quickly as standard down. But it will eventually become saturated and stop keeping you warm.

Because of this, the Rab Kaon can retain more of its weight and keep you warm for a more extended period.

While down jackets are great for keeping you warm in cold, dry temperatures, they do not dry quickly. So if you are taking your down jacket on an adventure with limited space, consider looking for a water-resistant option.

Synthetic insulation

The Rab Kaon Jacket has a hybrid down-and-synthetic insulation system that zones the warmth. The down-filled core keeps you warm and dry, while the synthetic insulation is used in the hood, shoulder and cuff area. The synthetic insulation offers durability, breathability and longer water resistance. The Rab Kaon has a high level of waterproofing and is also a very lightweight jacket.

This jacket has a fully-insulated hood, a high collar, a single chest pocket with a reverse coil YKK zipper, and a YKK calendared front zip for extra wind resistance. The YKK reverse coil chest pocket is a perfect place to store a compass, and the zipper is easily accessible even with a harness.

Zoned insulation

The Rab Kaon Jacket is an excellent mid-layer for those who spend a lot of time on the move. Its lightweight construction and zoned insulation make it perfect for various activities. The down filling is 800 and provides toasty warmth, while synthetic insulation sits over the shoulders and hips for added performance when wet.

The down insulation is protected with small baffles to prevent it from moving around. The jacket is also made from Pertex Quantum fabric, which allows air to pass through and regulate body temperature. The jacket also features a down-free underarm area.
