The Mountain Equipment Men's Triton Jacket is a waterproof down filled insulated jacket designed to provide maximum warmth and weatherproof protection.

The Triton Jacket is designed to be lightweight and warm, providing the functionality you need to perform in the coldest of conditions. Insulated with high quality water resistant 90/10 Pure Down with a fill power of 700, the jacket provides superior insulation with an excellent warmth-to-weight ratio.

For waterproof protection, the jacket uses Stretch Drilite waterproof fabric. The fabric is waterproof (with a 20,000mm hydrostatic head), windproof and highly breathable (with a MVTR of 20,000g/sqm/24h) The fabric utilises a Monolithic Membrane to transport water vapour out of the jacket while forming an impenetrable barrier to external water and wind. Stretch Drilite is a 40D fabric with 70D reinforced weave for superior durability with the added benefit of stretch performance.

A stitched-through narrow baffle construction is used throughout to enable optimum insulation while keeping weight to a minimum. The hood is an adjustable Mountain hood.

Other features of the jacket include two zipped hand warming pockets, a napoleon chest pocket, an inner zipped security pocket and adjustable cuffs.

Down Weight: 154g of 90/10 Pure Down with a fill power of 700
