ULAC Coursier GT Max 4.2L

ULAC Coursier GT Max

Big rides call for big carry.

Meet the biggest bag in the Coursier family – the GT Max. With a whopping 4.2L of waterproof storage, it’s made for riders who carry more than just the bare essentials. Rain jacket? Check. Snacks? Sorted. Even space for a phone up top in a quick-access pocket.

Elastic straps on the top let you stash sunnies or a windbreaker without opening a zip. Speaking of zips, it’s got a smooth double-zip entry and comes with its own waterproof wallet tucked inside—ideal for cards and coins when you’re grabbing a post-ride coffee.

And no, you don’t need a front rack. The smart design stays balanced and stable with just 3 velcros and a multistrap to keep it planted on your bars.
