DRILITE® LOFT 40D

The original Drilite® Loft , launched almost 30 years ago, was years ahead of its time: a highly breathable, lightweight fabric with excellent water repellency. These three characteristics are still present on modern Drilite® Loft fabrics. Drilite® Loft uses a polyurethane membrane bonded to the back of a nylon Face to provide dramatically improved water resistance, exceeding a hydrostatic head of 1500mm. Over its illustrious history, Drilite® Loft has been at the summit of most, if not all, of the world's 8,000m peaks, has been used on Piolet d'Or winning expeditions and on world record Fleeces traverses.

DOWN CODEX®

This is a promise that the down in all of the brand's products is obtained in compliance with the strictest animal welfare guidelines. The supply chains are 100% transparent and the quality of batches of down can be consulted and monitored online.
