RRP: $545.41 @ Peak Design.
Definitely the cheapest I've seen the Peak Design Everyday Backpack for, by all accounts it is an excellent bag for camera gear or just normal use, and comes with Peak Design's lifetime warranty and customer support, which in my personal experience is excellent.
An iconic, award-winning pack for everyday and photo carry, Peak Design 16" Everyday DSLR Backpack V2 30L is built around access, organisation, expansion, and protection. Unique MagLatch hardware provides lightning fast top access, with dual side access via two weatherproof side zips. Inside, 3 configurable FlexFold dividers keep photo, drone, or everyday gear organised, protected, and not bunched at the bottom of your bag. Dedicated sleeves for up to most 16 laptops, tablets, and documents, plus a variety of internal slip pockets for small items. Outside, a 100% recycled 400D weatherproof shell keeps everything safe. Huge external carry capacity made possible by a versatile tuck-away strap system and 2 expandable external side pockets. Integrated luggage carry makes this bag equally suited for daily commutes and extended travel. Zero-slop design with a clean profile, all-custom hardware, and minimal dangling straps. Now in its 2nd generation, v2 boasts aesthetic and functional updates based on feedback from thousands of passionate customers.
