Transit Carry-On is a spinner, ideal for the smoother terrain of urban environments, where you're mostly rolling – and turning – on flat surfaces. Ours has an immaculate glide thanks to the soundless wheels. It has been tested to last 10 years. The testing approach is to find all of the stress points and simulate years’ worth of wear on those spots. To ensure they're adequately reinforced, and robust enough for lots of travel to come.  Fix-it Kits are available for key parts in the unlikely event that parts need replacing. The space is used to its full potential, with internal organization that’s part permanent, part portable – and all versatile. Instead of choosing an off-the-shelf option, Bellroy designed their own: in a smooth shape that feels delightful in-hand, with an ergonomic underside button and 3 lockable heights. Crafted from super-durable matte polycarbonate, the shell is 80% recycled – the bulk of the interior strength comes from this recycled content. The shell is strengthened by impact bumpers, made by adding extra material in a curve for added surface tension – and bonus aesthetic interest. This helps prevent the usual cracks in hard shells around the top and outer edge. The grab handles are rafted from a blend of recycled nylon and polyester yarns and reinforced with polyamide 6 (the super strong one), they’re made to last – and to feel good. 4 HINOMOTO Lisof® Silent Run wheels are ultra smooth and soundless, thanks to the rubber compound. Plus, the polymer in the wheels is a bit bouncier than usual, adding impact resistance. TSA locks are a globally recognized system for locking your luggage, meaning your case can be checked by security without breaking the lock. Transit Carry-On has combination locks that the zip sliders click into. The main zipper is extremely smooth and durable, an abrasion-resistant YKK Racquet Coil zipper with water-resistant coating. The packing cells are customizable with easy-use toggle attachments. Keep just one (for items that you want to suspend right at the top in transit), switch them around, or use them as an internal divider. Plus, easily hinge them out to access underneath when you’re at destination. While the packing cells are designed to hold your miscellanea, the main zipped compartment is a good drop-in zone for larger items. And we placed this zipped compartment on the top side, so when you open the case, everything on this side is contained as it flips over. Flat-item storage is ideal for a laptop, tablet or e-reader, this sleeve provides quick access to any flat items. Devices will have some protection by virtue of being in the center of your luggage – but still, keeping them in their own cases is a good idea.
