Mountain Equipment Paiyu Men's Jacket

A very warm and compressible down-insulated jacket suited to mountaineering and climbing in colder conditions. The Paiyu Jacket is an innovative insulator, using a dual-layer offset baffle construction and integrated reflective layer to improve thermal efficiency.

With a unique construction, the Paiyu Jacket provides levels of warmth and protection far beyond its first appearance. With high levels of insulation and a full expedition specification, it’s a reliable choice for 5 and 6000m peaks as well multi-day ski journeys and anyone spending extended periods in freezing conditions.

Our dual-layer offset baffles remove the cold spots found on most comparable jackets using stitch-through construction and provide appreciable extra warmth with only a marginal weight penalty. This is backed up with heat reflective internal fabric to give even greater thermal efficiency when you need the absolute maximum insulation for every gram carried. Less bulky than the sort of box wall construction normally required for this level of warmth, the Paiyu remains a jacket you can move in on the very coldest days.

Our Mountain HC Insulated Hood provides essential extra protection on an exposed summit push and easily adjusts for the ideal fit with or without a helmet. An inner zipped security pocket and two large internal mesh pockets ensure vital kit and water doesn’t freeze as the temperature drops further still.

Specifications

Technology

	Down Codex Since 2009, our DOWN CODEX® programme has set high ethical standards for down sourcing, eliminating live-plucking and force-feeding, and ensuring only top-quality virgin down is used, certified to the Responsible Down Standard (RDS).
	Drilite Loft Drilite® Loft is Mountain Equipment's exclusive range of highly water-repellent fabrics used in their insulated clothing and equipment. The original Drilite® Loft introduced almost 30 years ago, was years ahead of its time: a highly breathable, lightweight, and very water-repellent fabric. Those three hallmarks continue with their modern Drilite® Loft fabrics.
	Down 700 Down is the finest insulator. Its warmth-to-weight ratio, compressibility, long lifespan, and softness are yet to be matched by manmade insulations. For all but the most serious expeditions, Duck Down is a great choice for both insulated clothing and equipment.
