This technical thermal 1/2 zip mid-layer is incredibly warm despite its low bulk and is ideal for cold days worn as a layering piece. The Matrix fabric is designed to do several things. The grid pattern helps to trap air which insulates the body. This same feature also creates low bulk which means that it will layer effectively over a base layer and under a jacket. It can also be worn next to skin if preferred.
The fabric moves moisture really effectively due to different sized yarn filaments on the outside and inside of the fabric known as denier gradient. This means that the sweat on the inside is drawn to the outside quickly which keeps you super dry.
This is the only mid-layer Ronhill range with a dual option of full hand mitt or thumb loop. A long centre front zip aids ventilation and reflective trim is on both front and back of the garment.
