[OUTER SHELL] A Trusty Sidekick / Your Name Is Top Tube Bag

It's already February. Time really does fly. (It feels even faster the older I get...) Before we know it, spring 🌸 is just around the corner.

Those of you who've been shivering and saying “It's too cold to ride!” might be starting to get around by bike a bit more. Lots of great items have been arriving, just in time for the “bikes feel amazing” season ahead!


The top tube bag: the classic of classics among bike bags, used by countless riders over the years.

Lots of OUTER SHELL users have been asking for one, and it's finally arrived!

What's so great about top tube bags?

The biggest appeal of a top tube bag is that it's storage you can easily reach even while riding.

It's perfect for things you want to grab while riding, or quickly take out and put back: your phone, snacks, keys, camera, wallet, and tissues during pollen season (I can't live without them!). Even if you suddenly crave a demi-glace omurice rice ball mid-ride, you can pull it right out.

  • You don't need something as big as a front bag
  • More stable than a jersey back pocket
  • Doesn't get in the way of steering

This “just right” position is why so many riders have loved them for so long.


What OUTER SHELL solved

Top tube bags are loved by riders, and plenty have come onto the market, but some of them

• Bump your knees or thighs when you pedal
• Wobble side to side while riding when only held on by straps
• Have zippers that are hard to open one-handed, with narrow openings that make it hard to get things out
•Are tricky to balance visually – they end up looking clunky


and so on. Maybe a lot of them ended up as “handy, but I stopped using it.”

This top tube bag solves those subtle “hmm...” frustrations.

OUTER SHELL have been making bike bags for years, and the reason it took them this long to release such a “classic” bag is all their trial and error, and their commitment to making something unlike anything else.


The OUTER SHLL Top Tube Bag

① No wobble, rock-solid stability

A lot of top tube bags tend to sway side to side or shift back and forth as you ride.

  • Works with both bolt-on and strap-on mounting ➕ a drawcord system that secures it to the head tube or stem
  • Built-in plastic frame with a dedicated shape
  • Non-slip rubberized bottom & Velcro straps with rubber lining

This combination delivers stability at the level of “once it's on, it doesn't move” and “it keeps its shape.”

You might be worried about the unused bolt holes, or whether it'll scratch your frame or gear, but rest assured: the foam-padded bottom fully covers the bolts, and the bolt holes when they're not in use.

It's not just about function; it's designed with care for your bike and your gear too.

② An easy-open zipper

One small but very real annoyance with top tube bags: they're “hard to open with one hand” and “hard to see inside.”

  • A separating zipper that opens wide
  • An opening that lets you see everything inside at a glance

It's designed so you can open and close it stress-free, whether you're riding or stopped.

③ Just the right size

Not too big, not too small: a perfectly judged size.

It comfortably holds the things you want close at hand, like your phone and a battery, a compact camera, snacks, keys, wallet and a mini tool.

It also has a cable port, so you can charge your phone while using it for navigation.


Tough, dependable materials and a design that puts “lasting a long time” ahead of trends: that's so very OUTER SHELL, and one of the things that makes them great.
