The Street_Satchel is designed to be an essential bag that travels with you everywhere. Slung across your back when walking the streets or on your lap in a vehicle. The Street_Satchel carries your most essential kit and never leaves your side.
We’ve made no compromises on materials.
The Mk I ULTRA version of the Street_Satchel is constructed of hard-wearing and lightweight Challenge Ultra fabric, which is made from UHMWPE fabric (learn more about the materials we use below). We use customised zips from YKK with water-resistant matte tape and black oxide sliders. Webbing tabs for optional accessories are also made from UHMWPE.
The sling attachment is 40mm polyester webbing. The satchel comes with a 40mm polyester detachable shoulder sling fitted with acetal hardware. The sling has a breaking strain of 900daN.
It’s possible that the Street_Satchel may actually outlive you.
We’re producing the Street_Satchel Mk I ULTRA in strictly limited numbers. Not because it’s exclusive, but because we’re limited in the volume of materials we’re able to purchase and our production capacity is constrained. As a result, we can only make these bags in small batches. Once a batch is sold out, it will take time to produce another batch.
Just enough features. Nothing extraneous.
Weatherproof materials and construction. Enough to survive an equitorial downpour. Not enough to be used as a flotation device to get across a river.
Slimline construction. You can flatten the satchel and slip it into another bag or you can wear it under a jacket.
Lightweight. If you didn't put anything in the satchel, you probably wouldn't notice you're wearing it.
The sleeve inside the main compartment will fit a 14-inch Macbook Pro or Macbook Air (in a form-fitting case).
Just enough organisation
The Street_Satchel has two compartments: a main compartment and a front compartment.
Inside the main compartment, there’s a section for a laptop (fits a 14-inch MacBook Pro). Behind the laptop section, there’s a Hidden_Pocket for A4-sized documents. In keeping with our design philosophy, there’s no padding for the laptop section, but we've added a stitch along the base of the section so the laptop doesn't sit on the bottom of the bag.
The front compartment contains an organiser panel with two pockets. The pockets are large enough for a small notebook and pen, a satellite communicator, a few rolls of film etc. There’s also another Hidden_Pocket inside the front section, suitable for your passport and a few SD cards.
We've carefully selected fabrics for their durability, light weight and water resistance.
Challenge Ultra is a laminate comprised of a 400D UHMWPE/polyester plain woven face with a 0.5 mm recycled PET film backing.
Whereas with DCF the outer material is polyester, with Ultra you're handling woven UHMWPE. UHMWPE has a more visible grain than DCF and feels more textured to the touch. It will also age differently to DCF.
UHMWPE fabric has an extremely high tear and tensile strength, and has maximal cut, abrasion, and wear resistance. The material is significantly stronger and harder wearing than DCF, but is slightly heavier (not enough to notice).
The UHMWPE/polyester laminate used with the Ultra fabric is also highly resistant to de-lamination.
Customised YKK zips for each application
After evaluating different types of zips and sliders, we've selected YKK zips sourced from Japan.
The zip for the main compartment is a custom-ordered #8 YKK racquet coil zip in a reverse deployment. The zip tape has a matte black PU coating to make the zip water resistant. This zip has head to head sliders, with a locking mechanism in case you want to lock the bag for any reason. The zip slider is finished in matte black oxide, providing a durable scratch-resistant and non-reflective finish. Over time, the sliders wear to provide a nice patina. Simple cord zip pullers are attached to the slider, enabling the zip to be easily manipulated while wearing gloves.
The zip for the front compartment is a #5 YKK AQUAGUARD zip. A 5CN DSBYG locking slider is used, and the zip pull tab can fold to sit flat against the bag. As with the main zip, the zip slider is finished in matte black oxide.
No hardware (at least, not on the bag)
The Street_Satchel has no fixed hardware. Plastic hardware tends to deteriorate over time, particularly in humid environments. Instead of installing hardware on the expensive item (the bag), we install it on the inexpensive item (the sling). It’ll be significantly less expensive to replace a simple sling than to replace the satchel.
After testing different types of hardware, we've selected acetal hardware sourced from South Korea. Unlike nylon hardware, acetal hardware is not affected by exposure to water or humidity.
Strong and lightweight accessory attachment points
We’ve sewn 25mm webbing tabs around the satchel as attachment points for optional accessories (these accessories are in the prototyping pipeline). Instead of using nylon or polyester webbing, we've used UHMWPE for these webbing tabs. UHMWPE webbing is light, supple and strong. Far stronger than it really needs to be for this application.
A basic shoulder sling is included with the satchel. For Mk I versions, the sling is made from 40mm polyester webbing. Polyester is ideal for humid environments, as it absorbs less water (and smell) than nylon. The sling is finished with acetal hardware, which performs better than nylon hardware in humid and wet environments. For Mk II versions, we've switched to a 50mm UHMWPE webbing and corresponding acetal hardware.
