This review references the replacement chest strap I just ordered because I lost mine but what I really want to say is: I bought the small Prvke lite (photography) pack for a trip to Ireland last fall, and I just love this bag. It’s like a tardis (small on the outside, big on the inside). I’m a small person and this pack was so easy on my back, especially with the sternum strap. The side grabber pocket for quick camera retrieval is a great feature. I can fit a Nikon Z8 body with 2-3 lenses (depending on which lenses), spare batteries, a computer or iPad, and my passport/phone in the secret pocket. I’ve used it since for walking event shoots with a flash and round diffuser in the upper roll part of the pack. I added a couple of the optional straps (I already had my own, they’re not as heavy duty as the Wandrd straps) and can attach either a small tripod or light stand and I feel like a lean, mean, well-prepared machine. It is quality gear and worth the price, so I’m happy to write a positive review. I’m sure the bigger bags are great, too, I was just on a mission to keep it light and compact when I bought this one. Mission accomplished. Thanks Wandrd! :)
