ARBPRO CLIMB TECH BASE LAYER is a close-fitting functional shirt designed as a first layer for physically demanding work, climbing and other active use. The construction combines three functional zones positioned according to the load on individual parts of the body.

Ventilation zones in the armpits and central back help wick away moisture and excess heat. Compression zones around the chest, lower abdomen and shoulders apply targeted pressure to stressed muscle groups and support local blood circulation. A 3D knitted structure in the shoulder area creates a cushioning effect and increases comfort when wearing a backpack or work harness.

The shirt is completely seamless, helping to reduce pressure and friction points during long-term wear. The material is treated with silver ions, which provide antibacterial properties and help reduce odour. A close fit is important for the correct function of the individual zones.
