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.

Great Garment

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.

Perfect cut

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)!

Dave Arnett
Great Addition

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!
Thanks Alpkit! smile


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!

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
-trimmed fit
-very light
-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

Grit.cx checks out Gravitas

Alpkit have added a range of waterproofs to their direct-to-consumer website. All are good value ..... Gravitas jacket is their super lightweight option though. It is not a bike-specific jacket, but ticks the boxes that I’m looking for. It comes with a fully featured hood, which will fit over a climbing (or riding) helmet, three layer breathable waterproof fabric, a chest pocket, a little mesh stuff sack… and little else
