First used it on a trip to Bali recently. Excellent shoulder straps design, no aching shoulders/back after hours of hiking/walking, very comfortable to carry with dlsr + 3 lens & flash, water bottle load. However, top and back cover zippers are finicky to pull, always gets stucked going around corners, slows down opening/closing access to gear and gets frustrating sometimes. The 3 Internal pocket zippers on back panel needs a protective cover tab to avoid rubbing/scratching gear/lens covers. They are just big shiny metal pieces dangling. With cover closed up and carried bag on back, it's just going to scratch some gears inside. Lastly, water bottle pocket needs to be a stretchable material, current doesn't expand to fit any water bottle with full gear inside Had only managed to slot 1 tripod leg in! More slots dividers will help with gear/space optization, the squarish slots are awkward to fit cam body or with lens attached.
