ULAC Radtail GT 5.8L

ULAC Radtail GT – Noir

Ready for rough roads and big rides.

The Radtail GT is built for the bikepackers and gravel roamers who ride far and pack smart. With 5.8L of waterproof storage, it offers just the right amount of capacity for gear-heavy day trips or minimalist overnighters—without the bulk of a full-size saddle bag.

It’s got all the details dialled: a waterproof inner dry bag for your essentials, versatile rear eyelets for mounting lights, a top multistrap for securing a windbreaker or pump, and a unique triangular karabiner for off-bike use. Mounts clean and stable with a mix of velcro and buckles—no sway, no rattle.

• 5.8L of thoughtfully designed space for real bikepacking use

• Waterproof dry bag liner for gear that must stay dry

• Rear and side light mount points

• Top multistrap for extra stowage on the go

• Includes triangular karabiner for added versatility
