Please see our gear tester review of the Cho Oyu over here on our blog.

The Dynafit Cho Oyu Women's Down Jacket, with 750 (eu) fill power combined with a Pertex Quantum outer shell means an excellent warmth to weight ratio. Typical Dynafit build quality combined with attention to detail means you have an insulated jacket that you’ll want to wear both on and off the hill for many years to come. The real story here however is the DownTek™ hydrophobic treatment. Traditionally the concern with reliance on down for warmth (especially in our damp Scottish climate) has been its performance in the wet. Wet down has the consistency and thermal properties of something akin to porridge. By applying a micro-thin nano polymer it is possible to vastly increase the water resistance of the down with dramatic results. This is demonstrated in the video below.

The Dynafit Cho Oyu is packed with clever little features. Especially worthy of note is the unusual hood design which is adjustable with one hand and includes a little stretchy gaiter to keep out draughts and spindrift. The fit is best described as “athletic”, narrow in the body and wide across the shoulders. It is quite common to go up one from your normal size.
