This Blue Camo PacSafe Slingsafe LX450 14L Backpack has some cool anti theft features! • RFID blocking pockets and material • eXomesh slashguard embedded in fabric • Carrysafe slashguard straps (metal in straps) • PopNLock security clip on backpack strap (for locking around something) • The zippers on the top main pocket also have rings that connect that you can buy a lock for. (Was not included) Also: • Has a laptop sleeve and fits up to 15inch. • Dimensions are: 17 in H x 12.5 in W x 4 in D • New with Tags! • Tags have instructions on how to use the PopNLock! Overall this backpack just gives peace of mind while traveling or in major crowded areas! Highly recommend! They no longer make this one and I personally think it’s their best style! It’s just the blue camo is no longer my style sadly! I bought this for a trip I had to cancel when COVID first hit and then moved shortly after. I completely forgot about this backpack and had left it in storage!
