When surviving the British '4-seasons in a day' weather, its much easier having clothes that are multi-functional. The Grid Technic does that by staying warm in the cold and cool in the heat, and wicking moisture away from the body.
The baselayer has a grid pattern which is the heart of how the equipment works. When worn alone the grid allows air to flow directly to the skin. When another layer is worn over the t-shirt the fleece fabric squares trap the air and heat up massively. The air can then circulate through the grid to provide warm air to the extremities and cool air to the armpits giving an even air temperature.
The Grid Technic uses Parameta® G fabric which provides both insulation and wicking properties. These properties work wonderfully with a Paramo waterproof, pushing any sweat you make out through the coat so you can stay dry and toasty, no matter the weather or the activity. The design includes a zipped neck, with a 'zip garage', thumb loops and an athletic cut.
