What is the difference between the B02 and a regular phone pouch?

The B02 is designed to do more than simply hold your phone inside a pouch. It features a detachable magnetic compartment that lets you move your phone from inside the bag to an easily accessible position on the outside. This allows quick access to your phone without repeatedly opening the pouch, making it especially convenient for urban mobility.

Can the magnetic compartment be used with the B01?

Yes. The detachable magnetic compartment can be switched between compatible B01 and B02 bags. The B02 is designed for minimal essentials, while the B01 offers more storage for commuting and short trips. You can switch between them based on your carrying needs.

Is the phone likely to fall off when attached to the magnetic compartment?

The magnetic compartment is designed with silicone limit structures to help securely hold your phone in place. For everyday use, make sure your phone is properly aligned with the magnetic area before carrying it.

Currently, the magnetic compartment supports the iPhone 12 series and all later iPhone models, as well as the Samsung Galaxy S25 Ultra. During strenuous exercise or high-impact activities, we recommend storing your phone inside the bag.

What are the advantages of X-Pac fabric?

X-Pac is a lightweight, water-resistant, and durable technical fabric with a recognizable diamond-patterned structure. It helps the B02 maintain its shape while keeping overall weight low, making it well suited for commuting, everyday carry, and urban outdoor use.

Is the B02 completely waterproof?

No. The B02 is made from water-resistant X-Pac fabric and can handle light rain and everyday splashes. However, it is not fully waterproof because water may enter through the stitching, zippers, and other structural openings. We do not recommend prolonged exposure to heavy rain.

Who is the B02 suitable for?

The B02 is ideal for people who prefer carrying only the essentials and want quick access to items such as their phone, ID, passport, or cards. Its compact design makes it especially suitable for shopping, traveling, dog walking, quick errands, and short commutes.

How should I choose between B01 and B02?

Choose B01 if you regularly carry everyday items such as a card holder, power bank, compact umbrella, or other small tech accessories.

Choose B02 for quick outings when you only need essentials such as your phone, passport, and cards.

If your carrying needs change throughout the week, the modular B01 / B02 system allows you to switch the compatible magnetic compartment between the two bags.

Is the B02 strap removable?

The B02 crossbody strap is adjustable but not removable. You can adjust the strap length based on your height, clothing, and preferred carrying position, whether you prefer wearing it closer to the body or lower on the shoulder.

Can the B02 be expanded?

No. The B02 has a fixed capacity of 0.3L and is designed specifically for compact, essential carry. If you need more storage space, consider the B01, which offers a larger 2–3L capacity.

Which phone models are compatible with the magnetic compartment?

Currently, the Detachable Magnetic Metal Compartment is compatible with the iPhone 12 series and all later iPhone models, as well as the Samsung Galaxy S25 Ultra. It is not compatible with other phone brands or models at this time.
