Price: 1,681.00 EUR

3A-5 is a messenger bag unlike all others. ǍCROŇYMř collaborated with legendary Berlin bike messenger bag makers BAGJACK® to develop this highly adaptive all purpose platform. Resilient. Modular. Dynamic. Evolutionary. Featuring sans velcro ACR-customized German mil-spec Kompression buckle dual mode storm lid closure. Ne plus ultra.

The 3A-5 has been pattern adjusted for improved fit, stability, and dynamics. Includes the removable (handy during airport security carry-on crackdowns) 3A-L1-15 laptop sleeve, removable dual internal pockets, and the new trolley back strap in addition to the top handle. Integrated dual external compression pockets feature our new thumb break roll-top closure for single-handed opening and closing. Strategically placed slotted loops allow for modular mount of 3A-MK1 and 3A-MK3 without the need for a full TEC SYS grid.

Based on technology derived from competition sailcloth, the FOIL F3 composite fabric delivers an exceptional use to weight ratio and a broken by design visual signature. The outer face of the fabric will crease and deform over time, creating irregularities that are intrinsic to the fabric. Surface deformation will vary with type and style of use.
