For many people, the Rab Ascendor Summit Hoody will seem a bit expensive, with features that smack of overkill; there are plenty of excellent fleeces out there that will keep you every bit as warm if used as a mid layer. However, Rab also offer less technical versions of the Ascendor (such as the Ascendor Light Pull-On), which are cheaper and more suitable for people who only want a warm layer for dog walking or wearing under a ski jacket. This one is for those looking for an extra level of outdoor performance.
It features body-mapped construction, but what does that mean? Essentially it’s a piece of fancy outdoor gear jargon that just means two types of material.
In this case there’s fleece on the lower body, back and forearms, while the chest, shoulders and biceps feature windproof Pertex.
This garment combines the warmth of a fleece with some of the weather protection of a softshell jacket. The Pertex panels are placed where you most want protection from the wind, and they will also shed light rain or sleet. If you’re a climber you’ll be pleased to know these panels are also much more abrasion resistant than fleece, and they are located where your body will come into contact with the rock face.
The fleece is gridded, featuring grooves that save on material weight and – in theory at least – trap air to help keep you warm. The hoody also features flatlocked seams and elasticated binding on the cuffs and hem. A dropped hem prevents it riding up above your waistline when you reach upwards.
The Rab Ascendor Summit Hoody is a pullover with a deep half zip that makes it easy to dump heat when exertion makes you sweat (although there is a full-zip version available too, and the women’s Ascendor Summit Hoody only comes as a full-zip top).
There is an under-helmet hood that hugs the head and offers a useful shot of extra warmth if you’re in the mountains during winter. You also get thumb loops to prevent cold spots between the cuffs and gloves.
Finally, there’s a small chest pocket that has enough space for a set of car keys but isn’t quite big enough for a mobile phone. The fit is trim, making it easy to layer under a warmer jacket or a waterproof shell in wet weather.
Rab Ascendor Summit Hoody: on the trails
I’ve been using the Rab Ascendor Summit Hoody as a mid layer for skiing, and wearing it as a standalone outer top for hiking. On a trek up Dunkeld’s Deuchary Hill the Pertex layer kept out the worst of a brisk wind. The extra ventilation of the deep zip was useful on the final push to the summit.
The gridded fleece and the brushed fleece backer on the Pertex both have a soft-feel; however, the Pertex does crinkle very slightly when you move. As a more technical top, I tend to use the Ascendor Summit Hoody less than other mid layers when I’m doing everyday activities. Its tight fit, technical appearance and crinkly face fabric make it less suitable for wearing around town or when out walking the dog.
But, when conditions warrant it (as they often do), or I was taking on a proper adventure, a more technical garment like this is the one I always reached for.
