The Full Story+

Designed for trekking, walking and active outdoor use, our Momentum Jacket is a lightweight, super-packable hard shell jacket that takes advantage of our 2.5-layer Barricade™ technology.

It’s totally waterproof, extremely breathable and completely windproof – offering a reassuringly high level of protection, without the weight penalty. In fact, its low weight combined with very compact pack-size, mean it’s the sort of waterproof that you can always stick in your rucksack - ‘just-in-case’.

The fabric itself is surprisingly soft and has a light, natural stretch to offer unencumbered freedom of movement without an unduly baggy fit – nice to have all the time, but really useful if you like to add a bit of hands-on scrambling to a typical day in the mountains.

Our Momentum Jacket features a full-protection mountain hood with a bonded peak and adjustments at the front and rear. When not in use, it rolls away neatly and is held in place with a convenient snap tab.

The two outer pockets are large enough to store an OS map and are situated above the line of a rucksack hip-belt. An internal pocket provides a secure storage option for outdoor essentials.

Fully adjustable cuffs and a shaped, adjustable hem, fine-tune the fit, keep out the elements and complete the specification of this impressive lightweight waterproof.



Our barricade™ waterproof technology achieves an initial Hydrostatic Head (waterproofness rating) of 20,000 and a Moisture Vapour Transmission rating for breathability of 20,000 g/m2/24h - a very balanced position.

A further Durable Water Repellency™ finish boosts water repellency of the fabric surface and maintains 80% of its effectiveness after twenty washes.

2.5-layer Barricade™

A perfect fabric for an all-round leisure jacket or one for gentle low level walking.

The water repellent face fabric and the waterproof-breathable membrane are bonded together. A partial print is applied to the inside face of the fabric to protect the waterproof membrane.

Washing Instructions
Caring for your Rohan Barricade™ waterproof will improve its performance and longevity. Simply machine wash your item at 30C with a gentle non-biological, liquid detergent. We recommend a second rinse to remove all traces of detergent from the fabric. Don’t use fabric conditioners, dryer sheets, stain removers or bleaching agents as these can impair the fabric performance. Garments may be drip dried. To rejuvenate the finish tumble dry your waterproof on the coolest setting, ensuring it is fully dry to complete the process.

Your Barricade™ waterproof has a Durable Water Repellency finish on the surface of the fabric. Over time, with wear and exposure to the environment, this can degrade, stopping water beading up on the surface of the jacket. Cleaning your waterproof will help maintain the finish. If necessary a re-proofing product, such as Rohan Proofer Wash In, may be used to restore the DWR. This can be used in your wash cycle and is activated by a cool tumble dry.

Elemental Protection
Wind - WindproofWind - Windproof

Cutting down windchill can make more difference to your comfort and safety than the amount of insulation you are wearing. We offer two ratings according to use: Windproof and Highly Wind Resistant.

Rain - Totally WaterproofRain - Totally Waterproof

Wet clothing transmits body heat nearly twenty-five times faster than dry. All clothing with this symbol is guaranteed to be totally waterproof. And highly breathable membrane technology means that you won’t get wet from inside either.

Functional Features
Secure Pockets x1Secure Pockets x1

Pocket science at Rohan is all about precision and detail of design, but most of all, it’s about keeping your most important stuff safe at times when losing keys, passports and wallet is more than just an inconvenience. We use several different methods – whichever is the most appropriate. Some pockets are completely hidden with micro zips, some are touch and close with roll-over tops and some are high quality zips.


Good design is more often about what to take off than what to put on. And clever design is about giving one feature two functions, that’s why many Rohan garments feature an internal mesh stretch pocket that doubles as a Packpocket™ for easy storage.

Our Technologies

Conventional waterproof fabrics cannot adapt to the changing weather outside and the changing micro-climate inside. Barricade™ is different, it is dynamic and responds to your body temperature and the humidity of the surrounding environment. The sweatier and steamier things get inside, the better the membrane works and the more vapour escapes.

Durable Water RepellencyDurable Water Repellency

Our durable water resistant finish, which forces water droplets to ‘bead up’ and run off the outside of the jacket, is designed to remain at 80% efficiency – even after 20 washes.

Fundamental Principles
Lightweight - Weight: 275gLightweight - Weight: 275g

We were the original lightweight revolutionaries. Back in the 1970’s we realised that cutting weight without losing performance meant that you can take less and do more. Everything we make is engineered to achieve this.

Packable - Pack Size: 850mlPackable - Pack Size: 850ml

Low pack size is a benefit whether you’re packing for a day’s walking or for the trip of a lifetime. We continually scrutinise fabric specification and garment construction to minimise the packed size of our clothing. The actual pack size is tested and listed.

Fast Drying - Drying Time: 9 hoursFast Drying - Drying Time: 9 hours

All Rohan clothing is designed to be very fast drying – as much a benefit for unexpected downpours as anything else. It’s easy to wash and often needs no ironing. Almost all garments will dry overnight, meaning you can take less with you. We test every item and list its drying time.

Momentum Jacket


I've had this jacket for roughly six months and during that time have been out in some terrible weather. I was in Ireland this July and one day for about 4 hours it rained non stop,

and for half that time the rain was torrential. The jacket has always been completely waterproof & windproof (so I find it hard to understand why another review claims the jacket leaked). This is a superb garment for the money being both waterproof and windproof.

Totally Waterproof to a Point


I recently purchased this jacket from Rohan in Truro. I have to say I was surprised at the new Rohan range, very up to date, I moved away from Rohan about 10 years ago as the clothing became very dated.

The jacket is extremely comfortable, and as I’m usually quite a warm person I wanted a jacket I can wear over a base layer that will keep me dry.

I gave it its first real test today, a 10k walk in awful weather, windy, almost steady rain appx 17c.

I wore it with an under armour base layer sweatshirt. I walk at a fairly brisk pace over varied terrain.

The first half of the walk I was still very dry, by the time I got to my destination I was still fairly dry, but not completely, so the claim of “totally waterproof” is not quite there.

At £180 price point, it should be what it says. Having said that I was amazed by how waterproof it was being so flimsy to the feel.

I remain to see how the durability of the jacket performs in the coming winter.

Lightweight simplicity


At around 100g lighter than the one I'm replacing, the new Momentum Jacket is great for summer use. Its simple construction saves weight, but it has all the essential features of a lightweight waterproof. Folding the hood away using the attached loop is a bit fiddly, but that's the only negative.
