A review of the – Sterkmann Expandable Carry on Backpack for men Overnight Weekender for Travel & Business Waterproof Fits 15″ Laptop With Packing Cube, Shoe Pouch & Laundry Bag (20L-30L Capacity, 3 lbs) – yes it’s a mouthful but that was basically the product description on Amazon!
This is a really great travel backpack with excellent build quality and a much lower price than the Nomantic backpacks without sacrificing the quality.
Note: I was able to fit my Sony A7III with the Tamron 28-75 lens AND the Samyang 35mm lens attached to the camera with all the stuff that’s already in the backpack!
