Modular laptop sleeve for all ACR 3RD ARM messenger bags. The sleeve mounts inside the main compartment of the bag:

1. Separate the white interior liner from the outer shell of the bag.
2. Insert the Velcro® top flap of the sleeve in-between liner and shell.
3. Reseal to finish.

Be sure to mount the sleeve to the back wall of the main compartment (side towards the body when worn) for best weight distribution. Make sure the sleeve lid wraps over the top edge of the pad.

All Acronym messenger bags can be retro-fitted with the 3A-L1 sleeve regardless of year of manufacture.

Based on technology derived from competition sailcloth, the new DIMENSION POLYANT® X-PAC composite fabrics deliver 3RD ARM bags with the best possible use to weight ratio. The same features at approximately 30% less gravity. Light and fast, literally.

Made in Germany

Available in a 13, 15, & 17 inch sleeve.
