Worlds apart comfort: a durable waterproof, windproof and breathable outerlayer for running, adventure racing and bike packing adventures. 

Gravitas is for fast and light activity where you want the protection of a fully waterproof, windproof, highly breathable shell but need unrestricted movement to run or ride at your peak performance. 

It is very, very light. At 170 grams it is one of the worlds lightest 3 layer jackets. Its simple and effective design features next to the skin comfort, a fantastic hood, large pocket, semi-elasticated cuffs and water resistant main zips. Packing down into it’s own pocket sized stuff sack, it is small and weighs less than your lunch.

It's brilliant to partner with our Laika or Koulin baselayers or worn over a softshell for when the weather closes in.

Chuck in your bag ‘just in case’.  Gravitas is the one jacket we take travelling or want to carry a minimalist backpack.

"all in all, an excellent, no-nonsense, shimmering shard of lightweight loveliness", Outdoors Magic

The state of the art ultra fine 7 denier nylon yarns in the face and back, and a super thin PU membrane, give the lightest 3 layer waterproof fabric we could find. 3 layer fabrics are class leading for comfort and more durably waterproof than 2 or 2.5L fabrics.

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)!

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.

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

Gravitas is light without feeling flimsy, has good levels of breathability and waterproofing and has been nicely put together from an impressively light three-layer fabric and its hood is quietly brilliant
