RAB KAON Jacket Review

When it comes to mountains and outdoor terrain, UK brand RAB have been a ‘go-to’ for any outdoor enthusiast, whether that be for the Himalayas, mountaineering, trekking, climbing or a leisurely walk in the outdoors.

2020 will see RAB launch a series of new products under the heading of SKYLINE a range of products made up of ultra-lightweight clothing that does not compromise on protection. Intended for ‘fast and light’ days that blur the line between running and technical scrambling.

It’s a significant movement for the brand and as a firm RAB fan, the SKYLINE range has already gained my attention and no doubt, it will grab the attention of anyone who likes to move faster in the mountains.

I will be introducing element of the new SKYLINE range over the coming weeks, notably, the SONIC SHORT SLEEVE TEE, PACER JACKET, CHARGE JACKET and PHANTOM PULL ON.

But first, the KAON jacket. 

The new KAON jacket personifies and sets out the stall of the new direction and although it does not come under the SKYLINE banner, it certainly ticks all the boxes offering minimal insulation with low-weight and packing size. Balancing lightweight, warmth and protection, the KAON uses a combination of 800 fill Goose Down and Synthetic Status insulation. Concentrating on the core, the Kaon retains warmth where it is needed, while ‘Pertex Quantum Air’ allows complete freedom of movement under the arms.

The Kaon offers zoned insulation allowing a balance between warmth without compromising movement. It mixes down for the core and ‘Stratus’ synthetic fill on the shoulders, hood and cuffs. 

The down in the core is 800FP hydrophobic down (70g in the men’s and 65g for the women.) This is significant as down, while warmer and lighter, cannot get wet – it loses warmth! However, hydrophobic down is treated with a durable water repellent that allows for quicker drying and the ability to resist water for longer. In a nutshell, it makes the Kaon far more usable in a variety of situations.

The Stratus synthetic fill is significant as it allows the jacket to be more breathable, dry out faster and is 20% less absorbent to other rival insulation. Synthetic is effective at keeping one warm, even when wet, so, it is ideal for damp/ wet conditions. RAB have added this to key areas of stress, either from the weather or equipment or a combination of the two. For example, on the shoulders, synthetic insulation will be far more durable with pressure from rucksack straps. Also, when compressed, it retains warmth, unlike down which requires loft.

The Atmos outer shell will still allow for loft while reducing down leakage making a perfect combination of warmth v weight.

Under the arms and down the side of the torso, Pertex Quantum Air is used which allows heat to escape and therefore allowing for body temperature regulation, always a difficult balance when moving fast and light.

IN USE 

The KAON is a wonderful crossover jacket for mountain runs and alpinists who want to move fast and light but be prepared for any potential inclement conditions that the mountains can throw at you. 

On first look, it is a simple jacket with a full-length zip, hood (that will allow for a helmet), high collar for warmth, one chest pocket, no side pockets and the sides and under arms use a different more flexible and breathable fabric. It has stitch through construction that provides a small square look to the jacket which ensure the insulation stays put.

The fit is slightly tailored, RAB say ‘slim’ but it is not super tight. Movement is not compromised. The arms are a normal length with a simple elasticated cuff. The jacket length sits just below the waist and for me, covers my backside. When zipped up, the neck goes nice and high and sits just below the chin keeping out drafts. The hood fits perfectly and has no adjustment – as mentioned, you can wear a helmet if required.

Needless to say, it is very light (240g +/-) and packs small and comes with its own stuff sack.

It is available in 3 colours, ebony (blue), firecracker (red) and dark sulphur (yellow).

I normally wear medium and medium is perfect in the KAON, size options are XXS to XXL.

 Having used the jacket as we transitioned from Winter to Spring, I have found it perfect or everyday use. On chilly days I start with it on and then remove when my core is warm. It packs away small and fits in the side pocket of my Osprey Talon 11 pack (to provide an example.) On warmer days, I have added the KAON to my pack in the assurance that should the weather change, I have an excellent light layer that will work. In conjunction with a lightweight jacket, such as the PACER (here) – I have warmth and waterproof for well under 500g.

SUMMARY

The KAON is one of those essential kit items when going to the mountains. It’s size and weight make it a ‘mandatory’ item for me – there is no reason not to take it! Warm, lightweight and packs small = perfect.
