A Tail Bag That Handles the Weather

Luggage is easy until it rains. Then the bag you strapped on this morning becomes the reason your spare clothes are soaked at the other end.

This one is built the other way round: a waterproof shell, covered zips and sealed seams, so the weather stays outside where it belongs.

Why Riders Choose This Bag

  • Waterproof shell with covered zips and sealed seams.
  • Expansion zip that turns a day bag into a weekend bag.
  • Four adjustable straps that fit almost any seat or rack.
  • Moulded top so it holds its shape when it is not full.
  • Reflective trim for visibility from behind at night.

Expansion zip on the waterproof motorcycle tail bag

Mounted in Under a Minute

Drop it on the seat, run the four straps, pull them even and buckle. That is the whole job, and it does not shift once it is done.

Taking it off is faster still, which matters at the end of a long day.

  • Waterproof motorcycle tail bag shedding water in the rain

    ★★★★★

    RODE THROUGH A STORM, STAYED DRY

    Caught ninety minutes of hard rain outside Flagstaff. Opened it at the motel and everything inside was bone dry, phone charger included.

    IT DOES NOT MOVE

    Four straps cinched down and it has not shifted an inch in two thousand miles. I stopped checking it in the mirrors after the first day.

    THE EXPANSION IS THE WHOLE POINT

    Small for the commute, then one zip and it swallows a jacket and a change of clothes for the weekend. I only needed one bag.

Genuinely Waterproof

Sealed shell and covered zips that keep rain, spray and road grime on the outside.

Expandable Volume

One zip takes it from a day bag to enough room for a weekend away.

Locked-Down Straps

Four adjustable straps with buckles that grip the seat or rack and stay put.

Holds Its Shape

A moulded top so the bag stands up on its own instead of flapping when it is empty.

Luggage That Keeps Up With the Ride

Rain Should Not End the Ride

The reason riders turn back is rarely the rain itself. It is knowing that everything strapped to the back is getting soaked while you do it.

The shell sheds water and the zips sit under covered flaps, so what you packed at home is what you unpack at the other end.

One Bag, Two Sizes

Most days you need somewhere for a jacket, a lock and a bottle of water. Some weekends you need a lot more than that.

The expansion zip runs around the body and adds real volume, so you are not buying a second bag for the trips that matter.

Why This Tail Bag Wins?

Waterproof Shell

Expandable Volume

Four-Strap Mounting

Holds Its Shape Empty

Reflective Rear Trim

Fits Seat or Rack

Adjustable mounting straps and buckles on the tail bag

Strapped Down and Forgotten

Four adjustable straps pull down over the seat or the rack and buckle tight. No bungees, no guessing, no watching it creep sideways in your mirrors.

It takes under a minute to mount and it stays exactly where you put it.

Interior compartment of the waterproof motorcycle tail bag

Packed the Way You Want It

A main compartment for the bulk plus interior pockets for the small things that always end up at the bottom of a duffel.

Reflective trim on the back means the bag works for you at night instead of just riding along.

Frequently Asked Questions

Is it actually waterproof or just water resistant?

The shell and seams are built to keep water out and the zips sit under covered flaps, so it handles sustained rain rather than just a shower.

Will it fit my bike?

Yes for almost any bike. It mounts with four adjustable straps over the rear seat or a luggage rack, so it does not need brackets or a specific model fit.

How much does it hold?

Enough for a jacket, tools and a day's gear at its normal size, and a weekend's worth once the expansion zip is opened.

Does it hold a helmet?

Expanded, it will take a half helmet or a skull cap comfortably. A full-face is a tight fit depending on the shell size.

Will it scratch my seat?

The base is a soft backing designed to sit against a seat. Keep the seat clean under it, as grit is what scratches, not the bag.

Can I take it off quickly?

Yes. The buckles release without unthreading the straps, so it comes off in seconds and goes back on just as fast.

Does it come with a shoulder strap?

It carries by the top handle. For off-bike carrying, most riders use the handle rather than a shoulder strap.

Will it move at highway speed?

Not when the four straps are cinched down properly. Snug each strap evenly and it stays planted.

How do I clean it?

Wipe it with a damp cloth and mild soap, then let it air dry fully before packing it away.

How long does shipping take?

Every order ships with fast tracked shipping and is covered by our 30 day money back guarantee.
