Aussie Grit Apparel Flint Bike Shell

Aussie Grit Apparel Bike Shell

Aussie Grit Apparel continues full steam ahead with ticking every box for the cyclists wardrobe.

This Aussie Grit Apparel Bike Shell has been in the ADVNTR offices all summer. But Autumn is finally the time to give it some proper use.

This is the Australian brands answer to the waterproof jacket. And like the rest of their product range, it’s designed for mountain biking first. But there is plenty of crossover for the adventure cyclist.

Looking mean and moody in a bright orange jacket is hard to pull off…

Available in black, charcoal grey and a hi-visibility orange as featured in our test. We’ve previously criticised Aussie Grit Apparel for their ‘trail ninja’ colours, so this brighter option gets a thumbs up from us.


This jacket has everything you’d expect in a waterproof: a high neck, dropped tail, sealed seams and some small reflective highlights to the front and rear.

The jacket is constructed from a 3-layer material with a DWR finish to deliver a waterproof breathable fabric rated at 20,000mm.

There is just one pocket, a vertical chest pocket with a waterproof zipper. I’ve never rated chest pockets on bicycle clothing. Stash anything more than a gel in there and the weight gets the call of gravity and just feels… annoying. The pocket also features a cable port for headphones if that sort of thing matters to you.

We like the bright orange colour on test. Aussie Grit also offer the Flint Bike Shell in more stealthy colours though…

The cuffs are elasticated and the dropped tail has a silicone gripper to stop it riding up your back. I really like the high neck and the full-length offset zipper on the jacket is great for grabbing on the fly to adjust your body temperature.

The fit

My first impressions of the fit were that it felt like a commuter style cycling jacket. It’s loose rather than whippet racer tight and the medium test sample felt just a little too baggy for my 5′ 10″ frame and 38″ chest.

Like most of the Aussie Grit range I’ve tested, the clothing is more ‘relaxed fit’, in mountain biker terms it would be more trail than XC fit.

In Use

I’ve tested the Flint Bike Shell Jacket in more than a few rain showers, the toughest test was 6 hours riding in continuous rain at the UK Fat Bike Champs.

The jacket is great at repelling light showers and acting as a windproof jacket, the high neck and dropped tail meant that everything under the jacket stayed dry. In heavier rain storms the durable water repellent finish of the jacket begins to struggle and wets out.

Giving the Aussie Grit Bike Shell some proper welly at the UK Fat Bike Champs

I didn’t find the jacket particularly breathable and got that boil-in-the-bag feeling very quickly at anything higher than low intensity cycling. There are no vents or ‘pit-zips’ to help regulate body temperature.

When the rain stops or you simply get too sweaty, the jacket is too bulky to pack into a jersey pocket. After ripping the seam on said pocket, I resigned to tying the jacket around my waist.


The Flint Bike Shell performs well as a wind and waterproof jacket, it is well made and durable. You can be confident that it’ll shrug off a life of off-road riding with ease.

If the Aussie Grit jacket was more competitively priced, it would be a viable option but feels too expensive at £199 for the features and performance on offer, especially when compared to the excellent and more packable Endura MTR Shell Jacket we recently reviewed.
