SLAM designed the Angler backpack for emergency situations out on the water, in the mountains and in the city. The combination of its manufacture using PTU and a wrap over closing system means not only that it is waterproof, but that the size of the same backpack can be varied. An internal laptop carrier features protective cushioning, internal thermo-welded pocket with zip, and a pen and document holder. There is also an external, appliqued expandable pocket and another in mesh. The back contains breathable padding. Laser cut lettering.
