Airtight Zipper, IPX7

The main compartment closes with a genuine airtight waterproof zipper across the top, and every seam of the 420D/501D TPU body is high-frequency welded with no needle holes. That is what earns the IPX7 rating — real sealing that keeps riding gear, electronics and a change of clothes dry through a full day of highway spray and rain, not just a light shower. We verify the seal on every unit with a full water-immersion test, submerging the closed bag for more than two hours and confirming the inside stays dry.

Three Ways to Carry — One Bag

The SL-E984 is built around a "strap, back, carry" concept. Quick-release straps lash it securely to a motorcycle rear seat or luggage rack for the ride; a removable padded harness board with shoulder straps clips on to turn it into a backpack for the trail or the terminal; and grab handles carry it by hand like a duffel. Switching modes takes seconds, so the same waterproof body works from the bike to the boat to the airport.

Removable Accessory System

Everything that makes the bag convertible is removable, so you only carry what the trip needs:

• Quick-release straps ×4 — lash the bag to a bike, rack or roll cage.
• Padded harness board with shoulder straps — clips on for backpack carry, comes off for tail-bag mode.
• Padded shoulder strap — for single-shoulder or hand carry.
• Phone pouch — a clear-window pouch for quick access on the move.

Rider-Ready Details

Reflective panels and piping lift night visibility on the road, a hook-and-loop patch panel with a "55" number plate takes brand or ID patches, side bungee cords stash a jacket or a helmet lock, and multiple compression straps and D-rings cinch the load and give clip-on points. The body holds its shape strapped down so it does not balloon in the wind at speed.

How waterproof is it?

It is rated IPX7 with a genuine airtight waterproof zipper on a fully welded 420D/501D TPU body, verified with a full water-immersion test of more than two hours. It keeps gear dry through highway spray, rain and brief immersion.

How does the 3-way carry work?

Quick-release straps lash it to the bike; a removable padded harness board with shoulder straps turns it into a backpack; and grab handles carry it as a duffel. All the carry hardware is removable.

What comes in the box?

The bag plus the removable accessory set: four quick-release straps, the padded harness board with shoulder straps, a shoulder strap and a phone pouch.
