The Petrolia is a dream for those who can’t leave things at home. The main compartment is cavernous, accessed via a wide top-opening zip which opens in the shape of a broad smile. You can fit most things you’d ever need for a day trip in here; the only trouble is the pack’s compression straps aren’t sufficient to keep its shape. I found it unbalanced and a strain on my back when fully loaded, especially given there is no full hip belt. There is a separate pouch at the back for a hydration reservoir, which ensures its weight is closest to the body – although the fiddly tube port means it takes a few minutes of swearing to get it set up. The back doesn’t offer much support or padding either. Without a frame, it’s a relatively lightweight pack, working better when stuffed with spare layers rather than heavily laden.
