The Kinesis Base Pants are an excellent base layer that excel in tough conditions. The active insulation provides warmth while effectively managing moisture and helping you regulate your temperature and stay comfortable for longer.  

Mountain Equipment says:

The optimum base layer for cold weather and expedition use.

Whether worn under hard or Soft Shell pants this is the most effective base layer you can use either on cold climbing days or extended expeditions. HeliumAP outer fabric and a specially developed Octayarn Warp-knit lining make the Kinesis Base Pants exceptionally warm and incredibly fast drying.

Mountain Equipment's Kinesis Base Pant provides an excellent balance of warmth with the ability to regulate temperature effectively. The design of these base layer pants combines a durable outer in areas of high wear with areas of limited outer fabric covering them maximising breathability. The active insulation on the inner keeps you going for longer no matter what the conditions are like or how hard you are pushing. They excel under a soft shell in cold, changeable conditions and under hardshell pants in full winter conditions.

The lightweight HeliumAP outer fabric is tough enough to use them without a protective shell occasionally but they are better under a shell and will certainly last longer. They have an athletic cut and are nicely fitted, not too tight and restrictive or too loose, which further promotes movement and sits comfortably under a looser shell outer.

The Octayarn Warp-knit is constructed to provide a greater surface area which promotes moisture wicking, combined with the hollow core of the yarn enhances the thermal capabilities of the Kinesis. In practice this was noticeable, keeping me dry the more intense activities got yet was kept warm as things became more leisurely.

Hot pants!

These are surprisingly warm for the weight ... like a synthetic pant, just better fitting, and easier to ventilate - like the windproof areas, great for when using the pants around camp, or hiking in them, if really windy, just pull my WP pants over and they are very warm - so in all, very useful for winter hiking, to use as camp or travel to/from destination pants - and for sleep pants, easily adding 5+ or more degrees to your bags/quilts comfort rating in my opinion.
