Worlds apart comfort. UKClimbing.com and UKHillwalking.com 'Best In Test' winner: 'Super-light and very breathable, the Gravitas manages to balance minimalism with functionality'

Gravitas is for running, racing and fast & light adventures where you want the protection of a 3 layer waterproof, windproof, highly breathable shell but need the unrestricted movement to run or ride at your peak.

It is very, very light. At 150 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 its 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.

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.

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

Environmental Considerations

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 Jacket

I purchased a size 14 Gravitas Jacket from Ambleside on Easter Monday , primarily as a lightweight, waterproof, windproof and breathable jacket for cycling. It was immediately put to the test and was not disappointed. over a 2 hour period of constant rain with the hood up under my helmet, I remained dry but more impressive was the breathability of the jacket. It has a great cut, the zip comes high to cover the chin and keep the weather out and the minimal features were perfect. The deep chest pocket is all you need for a phone and snacks. A well thought out design and another Appkit success.

Like my gravitas

A lovely lightweight jacket that does what it says. Waterproof & lightweight, well cut and nice to wear. Could be improved with a tab to hold the hood down when you run (especially with the wind behind) as it "bobs" around . Also beware that the pocket zip is not waterproof, it killed my phone!!

Fold up rain jacket

This is a lovely light weight waterproof, good shape but I felt slightly tight on my usual size 12 so had to return for a 14. Especially if i had more than a t-shirt underneath . But overall very happy.

Very disappointed in the quality and Alpkit

I bought this jacket last October, after reading how good it was and that it was FRA recommended, fab I thought this is a jacket which although light weight will stand up to the job. How wrong was I!! I bought it as my summer light weight waterproof for FRA kit check. I've worn it several times to test out for the summer, used it with a bum bag as I would when racing and was disappointed to find that it had worn in several places, the outer layer wearing away, in very little time and use.
I thought this was very poor and I'd not had anything like this happen with my other light weights, it has happened so quickly and the material just isn't up to the job, very disappointed.

I contacted alpkit about this and being local took the jacket to show them, thinking maybe mine was a rogue jacket. But was told that the jacket had been used alot and had worn. When I explained that I didn't think the jacket was up to it's supposed job, I was told it was a light weight jacket and what did I expect, said I expected it to be fit for purpose, FRA Fell races, where you're required to use a bum bag or pack to carry your required kit. I was told I could pay £10 and have the jacket mended. I declined this offer as I'd rather put my money towards a different brand jacket that will be fit for purpose rather than pay more money for this one.

So much for alpkit's three year alpine guarantee!!

Disappointed with the product and with Alpkit's customer service. Very poor.

My recommendation is don't buy this jacket

Gravitas Full Review

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

as perfectly suited for being stowed for emergencies or used frequently as a minimalist jacket for fast moving days.

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
