ULAC Radtail GT Pro 8.8L

ULAC Radtail GT Pro – Noir

The long-haul champ of the Neo Porter lineup.

Packing for a multi-day mission? The Radtail GT Pro has your back—literally. With a cavernous 8.8L capacity, it’s the biggest bag in the Neo Porter family, made for long-distance touring, gravel escapes, and bikepacking adventures where space (and waterproofing) is everything.

Built tough with ultra-light waterproof fabric, the Radtail GT Pro includes a removable inner dry bag to keep your gear safe when the weather turns. It mounts securely with a mix of velcro and buckles, and features multiple eyelets for rear lights and a top multistrap for stashing a pump or jacket. Bonus: the triangular karabiner gives you added flexibility off the bike.

Why we like it:

• Huge 8.8L volume – perfect for overnighters or long days out

• Built-in dry bag keeps contents sealed and sorted

• Top multistrap for extra gear like windbreakers or mini pumps

• Light mount points at the back and sides

• Triangular karabiner included for versatile use

• Lightweight for its size – just 315g
