The Kamleika Jacket has been updated this season with improved breathability and improved durability. It still has the same stretch, level of protection and some practical features that made the previous version such a success.

OMM says:

On the track; an athlete wears a Lycra, on the mountain; a mountaineer wears a Gore-Tex Proshell. The Kamleika takes the athlete onto the mountain with a shell layer that protects from wind and rain while stretching to give freedom of movement and so aiding athletic performance. Highly breathable, lightweight and now even more durable in a new Nylon face fabric. Kamleika is the choice for people who have recognised that they may have to wear a waterproof all day and yet still head for the fells anyway.

The Kamleika was, and still is, the original stretch running waterproof. Running in the mountains, in the rain, throws up as many challenges for kit as it does for people. This is particularly true when designing a waterproof where a blend of properties must be achieved. We demand durability, comfort, stretch, weather protective features, low weight, waterproofness and breathability, all of which must be balanced in the perfect combination. The Kamleika is OMM’s answer to this challenge. Updated for winter 2020 with a Nylon outer layer, it is now more durable than ever.

The History:

OMM invented stretch waterproofs a little over 20 years ago, and the Kamleika was the first waterproof to introduce true stretch. We’ve improved on the technology over the years to reduce weight, improve breathability and add features but the formula has stayed the same. Now in its 5th generation, the latest Kamleika builds upon decades of design and thorough testing in the harshest of races.

OMM's 2020 Kamleika Jacket uses the new and improved Kamleika fabric with a more durable nylon outer which still maintains a soft, stretchy and comfortable feel. It doesn't feel like a traditional waterproof shell, in fact, the material doesn't feel waterproof at all. However, it is waterproof and it works really well and has an increased level of breathability in this version. On a simpler note, the style and range of colours in this jacket is the best yet.

It may not be ultralight in comparison to some of the more basic race shells but it is much more durable, have a number of excellent features and will be able to cope with the harshest conditions you are likely to encounter on the hills and mountains. Some slight changes to design features have been made with the hood the most noticeable. The rear adjuster is must better to use and there is an internal cradle but I don't think it works as effectively as the old draw cords when the weather is challenging.

Avoid completely

This is a nice jacket - reasonably waterproof, lightweight, comfortable and looks good. The disadvantage is that the pockets are attached to the inside of the jacket with water soluble glue. This means that when it rains, the pockets will detach and anything you are carrying in them will fall out. I lost my mobile phone and glasses this way when walking in Skye a few weeks ago and was lucky to retrieve them. I returned the jacket to Ultralight Outdoor Gear and they kindly agreed to give me a refund. (Though it has to be said that unfortunately they lost the jacket and 3 weeks later I'm still waiting for the refund to come through). The older OMM "Event" jacket, which the Kamleika seems to have replaced, was much better as the pockets were sewn in as well as glued. Quite why OMM thinks they can sell a product which is so obviously unsuited to its purpose is beyond me.
