The chemical finish that keeps water beading off your waterproof jacket has changed.
As with all waterproofs from responsible outdoor brands, our waterproof jackets meet international environmental standards and require occasional washing with a technical wash to maintain their high breathability.
This wasn’t always the case. Years ago, waterproof jackets were treated with chemicals that had toxic by-products that lingered in the environment for generations. Those old chemicals needed little maintenance, whereas modern waterproofs need regular washing.
We fully support this change. In fact, we quite like the idea of taking time to look after our kit so that it lasts a long time.
We are committed to reducing the environmental impact of all our products –in fact it’s in our DNA: we can’t imagine ever doing anything else. We always review the materials we use, manufacturing methods and our own consumption of resources. We do the research, make informed decisions, and choose the best option available to us.
Product Care Information
To maintain the high performance of your waterproof, we recommend you wash and re-proof once or twice a year using specialist products like Nikwax or Grangers. For more information, read our detailed care instructions.

Gravitas 1st use
SIzing is on the athletic/ slimmer side so suited to wearing over lighter weight clothing rather than thicker fleeces etc. Consider this on sizing when buying.
Hood well designed and cinches nicely with a single draw chord to the back of the head, wired peak works well to keep eyes and vision clear.
Personally feel it could do with a slightly longer back or overhaul lower hem, but this a minor gripe.
I am new to Alpkit products, but I have become a big fan of their ethos, service and product quality. The Gravitas jacket is fantastic, with an unbeatable combination of function, weight and price. I am a 80kg male, with 42" chest. I bought the large size, which will be fine for 3 season use, over a single layer. For winter use over a base layer and fleeces etc., I might have chosen XL.
Bought as a lightweight jacket for backcountry cycling adventures that doubles as light tramping jacket. Owned for a month now and, it being winter in NZ, it's seen quite some rain.
The cut is perfect - long sleeves and tail, and fitted enough so there's no stomach bagginess when on the bike. Ideally they'd be a velcro tab to roll the hood up and stop it flapping, but I can live without one, or add one myself. The hood works brilliantly too, no drooping over eyes.
Material sheds water and doesn't rustle. Nice. For regular riding it's kept me totally dry. Being able to push the sleeves right up is a neat touch. I have found the limitations of waterproofing though. A 5 hour tramp in constant rain, carrying a full 40l pack saw water seep through to the inside the shoulders and back where the pack was. There wasn't much, and I wasn't wet underneath, but the inside of the fabric was damp. I'm assuming it wasn't condensation as it was blummin' freezing and I wasn't working hard (an easy walk with kids). But I'm putting it down to finding the limits of a jacket not really designed for that level of pack-carrying or NZ rain. I was expecting to find water had got through the zip, as it doesn't have a storm flat. But nope - all dry there.
So. Great jacket, very very happy. I'm now adding a Balance for those days when I need something heavier.
Bought this recently to use as a super lightweight adventure racing jacket.
It fits my large frame well. Arm length and jacket length are perfect. I particularly love the cuff design. The hood is really great too. Again the design touchs work really well providing simple solid protection.
I used mine on a very wet and windy Lakeland day and found it kept me dry and more importantly I didn't feel clammy. That's something else.
Overall, great jacket, super lightweight and thoughtful design and great value make this a really Brilliant jacket.
Well done Alpkit (again)!
Can't fault this jacket really. It's so lightweight but durable, windproof and of course waterproof. Had it in the rain all day and it held up great.
Really great jacket!
I bought this jacket last summer as a lightweight jacket to carry in my bag.
The Gravitas looks great, weighs nothing, packs down very very small (the gravitas jacket along with Alpkit’s parallax waterproof trousers fit into one small stuff sack) and is properly waterproof unlike the other minimalist jackets I am aware of anywhere near this price.
The fit is great and while saving weight and bulk everywhere, the jacket still has the features you really need (wired, adjustable hood, elasticated cuffs, good sized single pocket, good zip and adjustable waist)
Although I bought the jacket for summer emergency use, I have used this jacket for cycle commuting all the way through the year and also found it to be the perfect jacket for ski touring on warmer days.
Really great jacket! Super lightweight and breathable. Not tested it under heavy rain jet, but i'm confident that it will do its job!
Im 195cm tall, 88kg (wide shoulders). Initially ordered L size, but it appeared bit too small for my purpose (endurance road cycling). Exchanged it for XL and now its great fit and will accommodate warm fleece under it.
And yes - customer service is outstanding!
This is an amazing top for the price. Packs down small! Great on the bike. Hills and pub.
Used for walking and hill running. It was bought as a replacement for a much loved minimal (one might say ....mus) waterproof that died of de-lamination. That jacket was v good, but this is better. Great fit. Fabric feels nice. Clever hood (hasn't blown off so far). 100% waterproof in moderately unpleasant wind and rain. Not faced a prolonged torrent to date - but here's hoping!
Light, simple and functional.
It works well. XXL fits me well. I'm 115 kilos, 180cm, wide shoulders, big chest and also a bit of waist. It fits snugly, but not tightly.
It seems waterproof, we got a rainstorm hiking in norway. We went into the tent after maybe 30 minutes, but it repelled the rain well.
Bought the gravitas today, ran out within 1hr of the purchase. OMG it does what they you Alpkit says it does. I felt amazing running out over the moors tonight, felt so much more comfortable with the correct gear. Ive put a live BLOG on my page to review the gravitas as i used it. All in all i give the gravitas a five star rating.
I ran in it, it worked.
So, bought the gravitas as i wanted a light waterproof jacket that didnt make me sweat. The Gravitas is a brilliant design with min attachments which makes things easy. Its got a zip and a draw cord for the hood and torso base line, brill and it works. Ive run quite a few miles in it now in rain mist heat you name it and i a score of 9/10 as there is always something more you can improve on.
Well done Alpkit.
Almost perfect, needs minor improvements
the Alpkit Gravitas is a very good waterproof jacket that will work well in many situations, either outdoor and in town, due to the discreet look.
I like the material, it is not noisy like many "WPB", it is waterproof and though wicking is always limited on those materials, it does not get too much condensation especially considering there are no vents.
And here is the first improvement I'd like to see, minimal pit-vents under the arms, thin and narrow velcro opening with mesh underneath, that would not add weight and hardly any bulk.
On the same line, the chest pocket is very good but the interior should be mesh fabric, given the position of the opening it could be a good venting option if the inside of the pocket was made out of mesh.
The fit is nice and follows the body well on the average-build bloke, the arms are long enough (yay!) and the cuffs are perfectly sized, though a longer back hem would be appreciated.
The hood is simple and effective, though not useful if you're using the jacket on your Mtb rides: the jacket fits well and does not really restrain the movements (ok, it pulls a little between the shoulders, but not too much) but the hood won't fit most of the helmets. Also no means to secure the hood in place.
-quiet and comfortable to wear fabric
-waterproofing and breathability are good
-well positioned chest pocket
-excellent arm length and cuffs
-nice choice of colours, some are really visible without being "in your face"
-good value for money
-no venting options (by the chest pocket or pit-vents)
-the hood is useful but would need some means to keep it in place
-for ease of packing, the hood should have a synthetic peak not a wired one
-no useful reflective points on the fabric, should have some in the arms and the back!
-could do with a 2-3" longer back hem
In a nutshell: would I buy it again? Yes, it is good value for money and being so light &small; when packed, can be used in many occasions.
Very disappointed (again)
I’ve had one of these in the bottom of my rucksack as a back up item for a while. I recently used it in steady rain for the first time and it simply couldn’t keep it out. The fit and cut are great but I believe that the material isn’t. By comparison, I have a slightly heavier Rab jacket made from stretch pertex which is 7 years old and still keeps the rain out for hours despite some heavy usage. The title of the review is down to the fact that my wife has had the same experience with her definition jacket - fit great, fabric performance disappointing.
Hi Simon, I’ve dropped you an email to determine whether you are experiencing ‘wetting out’ of the material (which should be solved by reproofing) or whether there is another issue at play. Thanks, Ashleigh
