Aerial arborist wet weather gear is always challenging; you often work in the rain, sweating from the inside - moisture is a problem. SIP approached the problem by developing Siopor Ulta as the fabric of choice for the new SIp Keiu HV rain jacket. Siopor Ultra is water and windproof, breathable, extremely comfortable, supple and machine-washable: these features make the jacket more comfortable to wear without getting too hot while working. Furthermore, Keiu's ergonomic fit is modern and stylish. The fluorescent orange makes sure that you can be seen in daylight as well as at night time. In addition, the jacket has good styling details, ventilation zippers, a hood in the collar, deep pockets and an extended back to avoid rain running into the back of your trousers.
