While the Arc ‘teryx Atom Hoody is not a new model there has been a comprehensive reworking of the sizing across Arc’teryx range so I was interested to see how it would compare against the two fleeces.

The fit is very good on my regular size large frame, being trim but not slim over a long sleeve baselayer and the arm articulation is excellent with no hem movement at all, wherever I put my arms. Stretch fleece side panels help both the fit and movement. The longer body is a practical length for a weather resistant layer, as it’s more likely to be used without a shell. The chest pockets are set just below mid-height, which makes them accessible when wearing a pack hip belt. However, they are slightly small and perhaps more for hand warming than storage. There’s an inner zipped pocket on the left chest which is a good size, but I’d prefer it on the outside for ease of access.

The cuffs are in a wide stretchy fabric and pull up to my elbow for some cooling but are a little tight. The hem is quite neat and can be cinched further with a hidden drawcord. The main body fabric is Coreloft insulation between lightweight polyester and nylon shells. I expected to overheat when working hard or when the temperature rose during spring, but I found myself very comfortable most of the time. Through winter the Atom was excellent. It breathes and dries very well and keeps its performance when wet. Unfortunately, the hood lets it down. It’s a loose fit but not helmet sized and the volume adjuster pulls the fabric back to expose the side of my face. Otherwise, it’s an excellent if expensive jacket.

How Peter tested

Peter has worn these on most outdoor trips from the Munros last winter to the warmer trails of early summer, as well as off the hill. He is 5’11” and takes a size large. Weights are from his scales.
