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 X-Pac™ composite fabric delivers an exceptional use to weight ratio and a highly resilient exterior face.
