Not built for the mountain, built for the 8:12 in the rain. The Cass bag starts as a duffel: a U-shaped flap opens the entire top, so you load it flat, then two padded straps raise it onto your back for a packed platform. The matte, PU-coated shell keeps the weather fully out, Rains' Danish rain heritage, scaled down to a weekend. Thirty-four litres, a side zip for grab-and-run items, and compression straps to lock a half-load in place. One dark, clean line, made for cities that don't check the forecast.
