Gravitas is one of the lightest 3-layer waterproof jackets available - a mere 150 grams for the Women’s size 10. It’s a dream to move in too with a quiet and supple fabric that’s comfortable next to the skin.
Its 3-layer fabric makes the Gravitas much more durably waterproof and breathable than 2 or 2.5L fabrics, and we’ve used an ultrafine 7 denier nylon to sandwich the super thin PU waterproof membrane, keeping you as light on your feet as possible.
..Read moreWith 30K MVTR breathability and 20K HH waterproofing, the Gravitas has all the performance you need to keep you warm and dry for sweaty workouts in hostile weather. A lovely, soft tricot knit backer eliminates any cold clamminess inside.
The large hood with a stiffened wired peak has a simple rear adjuster and a semi-elasticated opening so you can yank it on in sudden downpours without stopping to undo your zip. The cuffs are cut to protect the backs of your hands and feature semi-elasticated openings for comfort. It’s also been designed with minimal seams and no visible stitching throughout to reduce snag and wear points, including on the ample-sized hidden chest pocket.
Feather-light and packing down into its own pocket-sized stuff-sack, throw it in your race vest for fell runs, squeeze it into seatpacks for bare-bones bikepacks, or even clip it to the back of your harness when the weather’s looking iffy.

Caring For Your DWR
To keep your jacket’s durable water repellent (DWR) treatment in tip-top condition, wash it regularly in pure soap or a specialist cleaner. You may also need to refresh the treatment about once or twice a year (depending on usage) using a reproofer. Using a spray-on reproofer maintains your jacket's wicking ability.
Washing Instructions
Wash on a delicate cycle at 30˚C or hand wash with lukewarm water. Use a technical wash product (like Nikwax Tech Wash or Grangers Performance Wash) or pure soap. DO NOT use detergent, fabric conditioners or softeners. Rinse thoroughly in clean water. Line dry or tumble dry on low heat. You can also use a cool iron to reactivate the DWR.
The Gravitas is treated with a PFOA and PFO free C6 DWR, cutting out some pretty nasty chemicals. However, we're still concerned about the potential impact of PFCs, so we're working hard to remove PFCs from our entire clothing range.

Travelling light and fast and putting a waterproof through plenty of miles
Super light, super waterproof, super breathable.
despite the super competitive £120 price-tag, this is anything but a budget effort
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
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
it is never out of that wash / dry / wear / repeat cycle
as perfectly suited for being stowed for emergencies or used frequently as a minimalist jacket for fast moving days.
the Gravitas is simply a really, really good lightweight waterproof shell full stop
The Alpkit Gravitas is not only great value for money, it’s one of the best lightweight jackets on the market
Super-light and very breathable, the Gravitas manages to balance minimalism with functionality
