STEIN KRIEGER "CLASSIC" Chainsaw Trousers Design "A" Class 1 (20m/s) KRIEGER "CLASSIC" Chainsaw Trousers, Design "A" Class 1 (20m/s), By utilising Armortex an abrasion resistant 4-way stretch base material the “Classic” trouser ensures the wearer has excellent flexibility in the areas which matter. The crotch area is fully constructed using the 4-way stretch material and the seams have been reinforced stitched for extra security whilst stretching. The fly-zip has been double cross stitched and clamped at the base reducing the risk of stress loads. A roomy tailored leg constructed with minimal seams ensures excellent air circulation reducing the need for un-necessary wear and tear points (e.g. zipped leg vents). The pre-formed knees give increased comfort and movement. Made from ArmortexKFM, this is a heavy duty waterproof, tear resistant Kevlar polyamide material. Integrating one of the latest European light weight technical blocking filaments means the Krieger’s are extremely light. The inner ankle hem is double lined to protect the blocking filament from boot eyelet wear. The outer hem is protected by a 55mm cuff of ArmortexKFM.
