Having previously tested and reviewed the original Kinetic Alpine pant we were eager to see what alterations Rab had made to the newly updated 2.0 version.

It’s instantly noticeable that Rab have not held back with making changes and have instead nearly completely redesigned the Kinetic Alpine. We often use our original pair, so having them side by side gave us a great insight into the changes made.

In a size medium the new weight of 328 grams is an increase of around 60 grams from the previous model but its easy to see where this has been distributed. Firstly the 2.0 take the appearance of a much more technical pant, reinforced Proflex woven fabric, rather than the ceramic print of old, covers mostly all the front area, with extra panelling at the rear around the seat and calve. The remaining sections using a lighter weight knit fabric, with similar stretch qualities we liked so much in the original. This not only provides a much more robust product but also changes how you wear the Kinetic Alpine.

We still get a lot of use out of the original, but it is noticeable that a few patches have needed to be added from nicks against sharp rock and a snag from a tree branch. The updated 2.0 certainly have addressed this issue and made for a more forgiving option which lent itself well for the days we spent this year scrambling steep rock in the western highlands.

The fit we found to be slightly loosened around the lower legs and a similar overall length as previously in a size medium.  Rab do offer a range of sizing’s including long and shorter leg lengths. The change to an elasticated waist with integrated belt is a massive improvement offering a secure hold. There is still plenty of storage space with 3 regular sized pockets with Aquaguard zippers, and a stuff sac to keep the pants neatly tucked away when placed in a pack.

For all day wear, the original option using the Proflex ceramic print divided opinion amongst our guides. There was certainly no denying that the stretch of the fabric and breathability was excellent. Where there were issues was how the Proflex felt next to the skin. The feel of the 2.0 isn’t quite as soft as previously and we were in agreement that they are much more suited placed above a pair of shorts or lightweight trekking trousers. Rab’s claim that the Kinetic Alpine 2.0 are, “the perfect pull-on, leave-on piece for fast-paced summer alpinists,” didn’t quite ring true with us. Although compared to most over trousers there is a noticeable difference in breathability, and for days out in mixed weather they are a very comfortable option.

The HH has now doubled to a very respectable 20,000mm. This is a much welcomed change and can be regarded as a proper waterproof option keeping us dry on many occasions including multiple very wet days in heavy downpours in the Cairngorms and a round of the Mullardoch/ Affric Munros. Re-proofing does need be applied more regularly compared to most waterproof products we currently use, although looked after well and they shed away rainfall with no bother.

There is still an issue with a short zipper at the ankle, meaning you must remove footwear first, not ideal when getting ready in a boggy environment. We fully understand that this strips down weight and is in keeping with the ethos of being an all-day pant. Although with the changes made elsewhere, we felt the inclusion of a longer zipper wouldn’t have added a considerable amount of weight.

Colour options and stylings are like most other Rab products. Streamlined and fairly low key, the Dark Ink we received is nice and simple although a brighter colour would be a great option to fit in with a broader range of activities.

Our Verdict
It’s hard to make a true comparison to the original model as the 2.0 version has a completely new outlook.Whereas the previous Kinetic Alpine was more of a typical walking pant that happened to offer a decent amount of waterproof protection, the 2.0 is pushing more towards a proper waterproof shell with improved fabrics and hydrostatic head that can handle persistent heavier downpours. Freedom of movement and breathability is still excellent, although used as a stand-alone garment against bare skin and the 2.0 doesn’t have the same soft finish of the previous model. It all comes down to personal choice and the activities you would look to undertake. The original model suited long-distance walking in a mix of weather conditions, where weight and comfort is an important factor. The 2.0 is better suited for more technical ground where the tougher fabrics and improved performance will long outlive the previous model.
