The most noticeable difference with the Gen2 will be the top main compartment flap and the embroidery logo. The new top flap is an improvement allowing for a larger full open entry access of your equipment while providing better weather resistance.Most everything else will be exactly the same as the original, Like the hidden Backpack straps, storable messenger side carry shoulder strap and cubic volume. Please see the photo gallery below. Cheers from Team NARGEAR!
