Surly’s frame bags are handmade in the U.S. by Revelate Designs using Dimension-Polyant VX21 polyurethane-coated fabric. They’re durable, rip resistant, tightly woven and laminated to be highly water resistant. Revelate advises using stuff sacks inside (such as those in which our bags are packaged) if you think you’ll be riding in extended downpours or underwater.
These bags use a ladder strap system, which lets you customize the fit and placement of the mounting straps. So if you have some weird contraption clamped to your frame tubes like a chain keeper, cable pulley or some trinket grandma gave you, you know it won’t interfere with the mounting straps on the frame bag. We also include foam bumpers for the mounting straps to minimize thread abrasion to the bag and attachment points. Quality YKK brand water-resistant zippers – with an improved, water-resistant zipper ‘garage’ – control compartment access and help keep the weather out. Zippers are sewn with a stretch panel to relieve stress, because yes, stress even kills zippers.
The large main compartment has a flexible divider inside, and there’s a hydration port to make sure your whistle stays wet. There’s also a compartment suitable for smaller items you’ll access relatively often, like your map, phone, hard-boiled eggs, uncontained pudding, marbles for playing marbles, your dugout, that ring you found that makes you disappear when you put it on, or what have you.
