Pro Review – Alpha SV


Dave Sarkar of Climbing Gear Reviews reviews this years’ Arcteryx Alpha SV.

I remember buying my first Arc’teryx Alpha SV, I bought both the jacket and pants second hand from a friend (there was no way I could afford a new one). I thought I’d hit the big time and the jacket lasted me nearly five years before I resold it on. It still had plenty of life left in it and fetched a great price. Thatís the pull of the Alpha SV, a totally bombproof jacket that should feel like you have retreated to the mothership when you put it on.

So, you can imagine my excitement when one of the new redesigned models became available for test. The Arcíteryx Alpha SV is still a highly desirable, fully featured and bombproof hardshell jacket. The 3 layered Gore-Tex Pro material has proved highly water and abrasion resistant throughout the test period and the jacket has become my go to shell for winter climbing. I have lighter and more compressible jackets but the Alpha SV is like wearing amour, when I put it on I feel like Iím totally ready for action.

As you would expect from a premium garment and a high end company, the Alpha SV doesnít come cheap; at £600 you might wonder why you would buy a jacket that is the price of a weekís Alpine Ice Climbing. Well, I think that in an age of super cheap kit that is next to useless the Alpha SV shines through as a bastion of high quality that will last you (as long as you look after and maintain it of course) for years of abuse. So, consider it an investment in your comfort and therefore safety.

The Arcíteryx Alpha SV is the ideal winter jacket for all conditions.

Letís take a closer look at the features and fit. Firstly the fabric: the Alpha SV is made from Gore-Tex Pro which is the top of the range Gore-Tex membrane. The N100p-X 3L membrane proved very breathable, in truth itís not the sort of jacket you might wear on the walk in in normal conditions, itís just too warm. The DWR is excellent and uses the new generation C6 PFCs which are a huge reduction in toxicity from the C8 PFCs.

Then the features: there are pit zips, which are nice and big so will offer plenty of ventilation if needed. I tended to carry the jacket into the base of the climb and then don my amour for climbing. The jacket felt breathable enough for me to feel dry as soon as I geared up and began to climb. I then felt comfortable through the day and only felt the need to put on a belay jacket for extended periods of belaying. Generally a good baselayer and my Arcíteryx Fortrez midlayer together with the Alpha SV have been a great combination. If the weather looks colder I wear a light synthetic vest and that increases my warm level. With this combination I have found that for most UK winter conditions I can carry a lighter belay jacket so have been using the Arcíteryx Nuclei AR and for lighter conditions my Nuclei FL.

The fit is generous in sizing, I am a size medium and the Alpha SV fits over everything I have on and still feels like it could accommodate more. This is great for winter climbing but can feel a little baggy for Alpine rock. One of the great comforts of the jacket is extra bit of length in the body, again perfect for those gnarly winter sessions when there is nothing more annoying than your jacket coming out of your harness waist Ė I have had this happen before, especially when squirming about in a Scottish chimney. The Arcíteryx Alpha SV has had some redesigns in the cut and the articulation in the arms is excellent, it doesnít look radical but is just enough to offer great movement with the arms rising at the wrists when your arms are over your head. This meant that when I tucked gloves under the velcro wrist tabs the arms stayed in position. Sometimes though I want to near gauntlets and the wrists tightened close enough for them to slide over the wrists nice and easy.

The burly fabric of the Arcíteryx Alpha SV is easily up to some winter thrutching!

Thatís not to say itís any heavier than previous versions, the redesign shaves weight off so the jacket is lighter than previous versions. The trusty CGR scales weighed the jacket in at 499g and the stated weight is 490g. Other significant features are the water tight YKK zips on the pockets Ė these are like YKK Aquacoil PLUS zips and have an extra coating to help keep out the elements and the main body zip is a good, chunky YKK Vislon zip that is the usual pull apart type of zip that Arcíteryx use on all jackets. Be warned that although this type of zip is great for ventilation, strong winds and heavy spindrift can open the jacket if you leave it undone! And talking of pockets the Alpha SV keeps itís Alpine credentials by placing the pockets firmly above the harness line and opposite hand accessible. The pockets are plenty big enough for everything you feel you might need to put in them on the belay or the descent. Gloves, maps, compass or topo they are nice and big but canít be used for keeping your hands warm, unless you cross your arms. There is also a ski pass pocket on the left arm and an internal zipped pocket to keep small items you want secured, such as a camera or phone. There is also a handy internal mesh pocket for stashing climbing gloves and food or liquid on the belay, which has proved a great feature.

As ever the attention to detail on the Arcíteryx Alpha SV is outstanding, the stitch count is very high and all stitching has micro seams to keep you dry. The stitching is just about invisible and the all the cinch cords are hidden well away. The reflective, embroidered Arcíteryx logo is a nice feature and the Gore-Tex logo is colour coded on the arm. The Arcíteryx Alpha SV ouses premium product and looks it too, Iíve been testing the Rhodes Green jacket and everyone Iíve met has commented on it: a real head turner.

Much is made of the redesigned Storm Hood on the Alpha SV. Itís easily big enough to fit even the bulkiest of helmets and although itís easy enough to adjust on the route, I found it best to make adjustments to it depending upon the activity. Adjustments are made using the rear head and neck cinch cord and two well hidden front adjusters, they are easily released using the hidden fasteners. There is further adjustment in the neck and this proved very useful in making the Alpha SV a true, bombproof weather resistant jacket. The hood is indeed an excellent hood and once adjusted I had full 180į visibility and the it never rode above my helmet. The brim is laminated and not wired but they never have been.

In conclusion, the Arcíteryx Alpha SV deserves itís title as the flagship Alpine jacket of the Arcíteryx range. The excellent and well thought out features shine through as a jacket that has been designed by Alpine climbers for Alpine climbers. Itís not the lightest jacket out there but it is the burliest jacket I have and is my go to jacket for Scottish winter and working on rainy days (which is more than Iíd care to admit!). It still retains its status as an iconic hardshell and if you can afford the price tag you will own one of the most desirable and performance designed Alpine jackets on the planet.
