Worlds apart comfort: a waterproof, windproof, and breathable outerlayer for moving fast and ultralight.

Gravitas was designed to give you waterproof, windproof, and highly breathable protection without restricting movement as you run or ride.

One of the world’s lightest 3-layer jackets at maximum 160 g, Gravitas combines state of the art, ultrafine, 7 denier nylon yarns in the face and back, a super thin PU membrane, and fully taped seams.

The minimalist design prioritises simplicity and next-to-skin comfort, featuring a neat hood, large pocket, semi-elasticated cuffs and water resistant main zips.

Packing down into a pocket-sized stuff sack, Gravitas is ideal for minimalist adventures or chucking into your bag for just in case.

"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.

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.

Claire Sheldon
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

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
