The best... insulated jackets

STAY SAFE ON THE HILL WITH A TOP LAYER DESIGNED TO WARM YOUR CORE

Hood

Insulated jackets retain heat by trapping warm air. Areas that let in draughts or cause cold spots can significantly reduce a jacket’s thermal efficiency. Look for front zips with baffles behind them, close-fitting hems, cuffs and collars.

Insulation

Both of the jackets featured here are made with synthetic insulation, which has a number of beneficial characteristics as opposed to natural down, being known to be warmer when wet and generally more robust. Traditionally, the drawbacks of synthetics are a reduction in packability and an increase in weight. However, modern technologies are constantly blurring the line between the two.

Chinguard

Easily overlooked, this small piece of material protects your chin from the top of the zip, which can cause irritation when moving your head. This can greatly improve maneuverability and comfort, especially in adverse conditions.

Weather resistance

These jackets are designed to keep you warm, not dry. But features such as Durable Water Repellency (DWR) can help reduce water ingress, outer fabrics that resist wind can increase heat retention, and even the structure of the insulation itself can affect how a jacket performs with anything from adverse conditions to condensation in a tent.

Pockets

Pockets are obviously useful. Their placement and size can affect a jacket’s versatility – a walking jacket should be able to carry a map and compass, whilst harness-compatible pockets are more useful if you plan on activities with more verticality.

Draught exclusion

Insulated jackets retain heat by trapping warm air. Areas that let in draughts or cause cold spots can significantly reduce a jackets’ thermal efficiency. Look for front zips with baffles behind them, close-fitting hems, cuffs and collars.
