The Defence Research and Development Organisation (DRDO) handed over technology for indigenous extreme cold weather clothing system (ECWS) to five Indian companies in New Delhi.

The technology was handed over to the firms by DRDO chairman G Satheesh Reddy on Monday (27 December).

The extreme ECWS is required by Indian Army for its sustained operations in glacier and Himalayan peaks.

The Army, till recently, has been importing extreme cold weather clothing and several Special Clothing and Mountaineering Equipment (SCME) items for the troops deployed in high altitude regions.

The DRDO designed ECWCS is an ergonomically designed modular technical clothing with improved thermal insulation and physiological comfort based on the insulation required at various ambient climatic conditions in Himalayan regions during different levels of physical activity, a Defence Ministry release said on Tuesday (28 December).

The ECWCS embodies physiological concepts related to reduction in respiratory heat and water loss, unhindered range of motions and rapid absorption of sweat while providing water proof, wind proof features with adequate breathability and enhanced insulation as well as strength features required for high altitude operations.

The three layered ECWCS is designed to suitably provide thermal insulation over a temperature range of 15 degree celsius to minus 50 degree celsius with different combinations of the layers and intensity of physical work.

Considering the widely fluctuating weather conditions in the Himalayan peaks, the clothing provides an advantage of fewer combinations to meet the required insulation or IREQ for the prevailing climatic conditions, thereby providing a viable import alternative for the Indian Army, the ministry said.
