Outer Shell Bike Packing Bags: Six Practical Storage Solutions for Overnight Adventures

Introduction

Outer Shell manufactures bike packing bags in-house in San Francisco, California. Their lineup includes six distinct storage solutions designed to work together for bikepacking overnighters. Each bag combines thoughtful design with durable construction, offering riders multiple ways to distribute gear across their bikes.

Frame Bags: Structured Storage for the Triangle

Frame bags sit inside the main triangle of your bike frame, offering secure, low-center-of-gravity storage. Outer Shell offers frame bags in multiple sizes: small, medium, and large. The bags maintain their shape thanks to sturdy internal structure, and they arrive with a finished appearance that feels premium.

Both small and medium sizes fit comfortably on modern gravel and road frames. The bags are designed to clear the front wheel and tire, though measuring your frame’s triangle dimensions before ordering is recommended. The construction quality is notable, with clean stitching and materials that feel durable enough for repeated use.

Mega Bar Bag: High-Capacity Handlebar Storage

The Mega Bar bag is a large-capacity handlebar pack that connects directly to your handlebars via an aluminum frame built into the bag itself. This frame acts as both a handlebar cradle and a structural support, allowing the bag to hold significant volume without sagging.

The bag measures approximately 8.5 inches from top to bottom, which is substantial enough to require clearance checks on smaller frames. An adjustable strap at the front allows you to pull the bag’s opening higher if needed, increasing usable capacity. The Mega Bar bag comes in multiple colors, including olive green and marigold, and fits well on both road and gravel bikes with proper measurement beforehand.

Stem Caddy: Cockpit-Area Convenience

The stem caddy is an oversized bag that mounts on your bike’s stem, positioning snacks and small essentials within easy reach during rides. The bag is large enough to hold water bottles, snacks, and other items you want quick access to without stopping.

This bag works well for riders who want to keep frequently used items in the cockpit area rather than buried in a frame bag. The construction is sturdy and the mounting system is straightforward, though installation with two hands is easier than attempting it solo. The bag comes in black and other colors.

Mini Saddle Bag and TT Bag

The mini saddle bag is a compact bag that mounts under the saddle, designed for carrying tubes, tire levers, and other small repair items. It comes with a wallet strap for organization and is available in colors like marigold. The bag is small enough to be unobtrusive but large enough to hold essential spares.

The TT bag is a smaller storage option that offers additional carrying capacity for specific gear. Both bags are designed to work alongside larger frame and handlebar bags in a complete bikepacking setup.

Magic Musette: Versatile Shoulder Bag

The magic musette is a shoulder bag that can be carried off the bike or attached to your setup. It is large enough to hold items like wine bottles, making it useful for both on-bike storage and off-bike carrying. The bag has a trendy aesthetic and works as both a functional storage solution and a stylish accessory.

Putting It All Together: Multi-Bag Setup

A complete Outer Shell bikepacking setup typically combines a frame bag, mega bar bag, stem caddy, and one or more smaller bags like the mini saddle bag or TT bag. The bags are designed to work together, with shared strap systems that allow you to consolidate hardware and reduce clutter on your bike.

Installation is straightforward once you understand how the straps connect. The frame bag and mega bar bag can share mounting straps if positioned correctly, simplifying the setup process. The stem caddy mounts independently on the stem, and smaller bags attach via their own hardware. The overall weight of the bags is light relative to their capacity, and the quality of construction means they will hold up to repeated bikepacking trips.

Conclusion

Outer Shell’s six-bag lineup offers flexibility for different bikepacking styles and trip lengths. Whether you are planning a short overnight adventure or a longer expedition, these bags provide practical storage without excessive weight or bulk. The quality of construction and attention to detail make them a solid choice for riders serious about bikepacking.
