Review: Pinnacle Waterproof Urban Backpack 18L

The Pinnacle Waterproof Urban Backpack is a great all-rounder bag. It’s become my go-to for daily commutes, trips to the shop and even days out, both on and off the bike.

The 18L capacity is just enough to fit in my work laptop, a change of clothes, puncture kit and lunch. You may need something larger if you tend to lug a lot of kit about.

At first, the waterproof material was quite rigid and had an audible squeak, but this disappeared once the material became more supple. Similarly, I found the straps overly firm at first.

They are stitched quite closely together at the top, which I thought would rub on my neck. But again, as they softened up, I didn’t find any issue here.

There is minimal padding, yet I found that the bag sat comfortably on my back and could withstand a decent amount of weight with ease.

The waterproofing worked well. The contents remained dry when testing it in rainy conditions. The roll-top design is simple and easy to use. There aren’t any internal pockets, which can make organising things a little tricky, although this wasn’t a major problem for a bag of this capacity.

On the outside of the bag, there are reflective anchor points, which I found useful for clipping on additional lights, or attaching my helmet when off the bike. There is also a mesh pocket for a water bottle on one side, and an additional see-through pocket on the other.

This is intended as a touchscreen compatible pocket for a phone. I never used it; a small, external zipped pocket for quick access to items like keys or a wallet would have been more practical.

Verdict

This was the bag I didn’t know I needed but have used almost every day since it was delivered. I love the simple but sturdy design and materials. As a commuter backpack, it’s great value and robust.
