Rab Mantra Jacket Review

Rab Mantra Waterproof Jacket

It’s been a while since I’ve had a decent waterproof shell jacket so I jumped at the chance to review this Mantra, breathable and waterproof jacket from Rab. I tested it in two locations, wearing different layers under the coat to see how warm and windproof it would be.

The Test

The first location was a wet and windy day in Porlock, and I mean really windy. For this test I wore a lightweight fleece pullover underneath. The Mantra was a good fit with plenty of room and would easily take a thicker base layer. It wasn’t needed though.

The hood

Once zipped up fully the Mantra covers the mouth well and the fleece lined chin guard makes sure there is no chaffing.

The hood is easily adjustable around the face and on no occasion did the bracing wind pull the hood from my head. I love that the dangling collar toggles for hood adjustment don’t have large adjusters that slap you in the face in harsh wind.  Instead two toggles are inset into the jacket on either side of the collar and from the outside of the jacket are invisible. Just press and pull on the toggle to adjust the hood opening. A drawstring on top of the hood helps slim down the inner of the hood as this jacket gives ample room for a cycle helmet. I’ll look forward to testing this on a less breezy day. The hood has a nice wired peak for added extra protection too.


The outer jacket has high outer pockets. At first I thought would be too high to put your hands in on a permanent basis but are in fact were quite comfortable.

The pockets are all a good size and Rab have put information cards in them letting you know that they are not suitable for electronic gear, like phones, unless they are waterproof or kept in a dry bag. This is down to moisture that can build up in the pockets, which are not fully breathable. A good size map pocket inside the jacket is also a nice addition.

Waterproof test

The Jacket’s Pertex Shield Pro 3L fabric has a soft touch, with no constant rustle when you walk. It also has a good amount of stretch. I wore this fully zipped for a good three hours and there was no sign of moisture inside the jacket so the breathability is excellent. With a fleece it was toasty and warm and it was very windproof. I also tried it with just a t-shirt and, while not as warm, it still blocked the wind nicely. I was battered with rain in Porlock but remained warm and dry throughout the walk.

The second location was a long walk from Creech St. Michael to Bridgwater along the canal. This was a warmer and less windy day with periods of light rain and sunshine. On the waterpoof side this jacket is fabulous. Rain ran off the jacket like water off a duck, so much so that it was hard to get a picture of water on the jacket. The AquaGuard main zip with inner storm flap did its job with not a drop of water seen at the end of the walk.

Added features

Nice little additions to this jacket are the very easily adjustable snag free Velcro cuffs and Velcro tab that allows you to roll up your hood (pictured left). The hem draw-cord is also a nice touch but is something I don’t tend to use that much.

At just shy of 15oz it’s a lovely lightweight jacket that can easily be thrown in a backpack and takes up very little room. It feels very durable and well made with great attention to detail. The style and fit were perfect and I’m looking forward to getting out more in the Mantra and even testing it while cycling.
