Mammut Kala Patar Tech (2014)

Not everyone likes pockets, and if you have a hands-on approach to your outdoor activities, such as when scrambling and mountaineering or just due to using trekking poles a lot, then do you really need them? If the answer is no, then the Mammut Kala Patar Tech may be for you. It’s made from a combination of two fabrics: one with a waffle backing to provide insulation, while the other has a more durable outer to prevent pilling. The more durable fabric is around the hood, hem and body sides, and under the sleeves. The more open weave waffle areas are great for allowing better airflow under a waterproof jacket. There’s a flap behind the main zip, which should keep draughts out of this area. The design is close-fitting, with elasticated cuffs that also have thumb loops, so it works well over a base layer and under other mid layers, soft shell jacket or waterproof layers. The hood has no adjustment but it provided a close fit on me, although it did come a little too close to my eyes to be comfortable. Overall the Mammut Kala Patar Tech is a useful mid layer to incorporate into a clothing system. The downside is that for this price you could get a very good pocketed fleece jacket that’s warmer.

The Mammut Kala Patar Tech is a useful mid layer garment for fast-paced activities like climbing or mountaineering if you don’t want pockets, but it isn’t as warm as thicker fleece jackets and so its price leaves me cold.
