Rab Vital Windshell Review

The Vital Windshell is made out of 20-Denier, solid nylon that is very tightly woven to resist wind but isn't at all stretchy like the old Windveil material. For all of its additional features, this jacket is still one of the lightest in our review. Particularly, it is a fantastic alternative to jackets that don't provide as much storage space. Besides the unique features, its best attribute is wind resistance. It is particularly suited to those who need something to cut the wind but aren't as concerned about how well it breathes or sheds light precipitation.

Performance Comparison

Wind Resistance

This is one of the more wind-resistant jackets we tested. On fast bike descents on cold mornings, we stayed relatively warm. Zipping around on bikes, we particularly appreciated how the Vital employs a number of features to block the wind. A storm flap behind the zipper helps block a piercing wind, and a fully elastic collar both keeps wind from running down your chest and the hood from flapping around.

We backed up our bike commute findings by taking the Vital to the top of a high pass in the southern Rockies and tested it in a strong, wintry wind. Beyond a tight weave that keeps the air from flowing through the jacket, we also appreciated how effectively the hem drawcords closed. The half elastic cuff is easy to slide on over another layer and keeps the sleeves in place. Together, these seal you off from the wind very effectively.

Breathability and Venting

This is where the Vital comes up a bit short. In side-by-side tests, while hiking and biking uphill, the Rab held more moisture than other similarly constructed windbreakers when fully zipped up. With no vents or mesh backing on the pockets, even if you unzip it, it isn't possible to achieve a good airflow. Not only that, but the Vital's pockets are lined with an extra layer of nylon. This keeps your sweat from getting to the pocket contents — a thoughtful touch — but it also reduces your venting options.

One cool feature to help improve breathability is the snap closure across the chest. This allows you to keep the jacket in place, even when fully unzipped. Although it might look a bit like a cape, we like this feature because it allows you to dump a lot of heat all at once without losing your jacket to a strong breeze.

Weight and Packability

At a weight of 4.7 ounces, our size medium is impressively light when compared to many other shells out there but still is about 20% heavier than our lightest windbreakers in this review.

The Vital conveniently packs into a zippered pouch that lives on the inside of the jacket — the only one we tested that doesn't simply stuff into its chest or hand pocket. Worth noting is that it also has a secure clip loop that keeps it from dangling as low as some other packed jackets when hung off of a harness.

We really appreciated how the zipper is not right at the top of the parcel pocket, which makes it surprisingly much easier to pack. The Vital packs down to the size of a Nalgene bottle, and for most people, this is plenty small. But it is comparably larger than some of the other, lighter jackets — this may make the difference if you are trying to stuff it into a small saddlebag.

Fit and Functionality

We tested a size medium and found that the overall fit is right in line with its purpose as a tech-hoody for alpine climbing or mountain biking. In contrast to some other tighter-fitting jackets, this one is long enough in both the sleeves and hem. It also provides enough space underneath for a puffy layer on colder days, proving that it works well as an outer shell.

This jacket has three large pockets — two large hand pockets and a big internal pocket that also serves as the stuff pocket if you choose to stow it. This allows more storage than just about any other wind jacket available. You can easily fit gloves, a hat, your wallet, and more. This is a key distinction with the Vital — you can easily integrate it into your everyday life.

Besides the pockets, a few other notable features are worth pointing out. Already mentioned is the snap button across the upper chest, but we also loved that a simple velcro tab adjusts the hood. This tab has the double purpose of allowing you to roll the hood up and velcro it tight if you choose not to use the hood on a windy day. Flapping hoods are annoying, and this simple addition — plus the fully elastic collar — helps keep the hood from slapping you in the face.

Water Resistance

This is one of the few jackets in our review that isn't supported by a DWR finish. While the ripstop nylon does a good job up to a point, we don't suggest subbing out your lightweight raincoat for the Vital.

During the lightest of rains — some may call it heavy fog — the Vital did just fine in beading up rain droplets. But the face fabric holds onto these droplets for a long time, and eventually, they begin to soak through in places. Our laboratory shower test supported these field findings.

Value

When it comes to functionality, the Vital is more than worth the price tag. All things considered, this jacket strikes a price-point right down the middle of our best scorers — a valuable jacket for the athletically inclined, just as long as you aren't consistently pushing hills while running or riding.
