The pocket is structurally quite similar to other bags in this price range, such as M-Wave, probably the stuff comes anyway everything from the same Chinese factory. The bags are stiffened by filler plates, which may be installed according to instructions "by adults". Aha. Although I am an adult, but could see no danger to life and limb for teens. The attachment to the rack with buckles for pulling through like 30 years ago is a miserable fumbling - almost a torture, but that depends to some extent by Porter from, one should not in any case be under the illusion of wanting to ever dismantle the part again. The lower attachment with a tired Velcro strips is also more decorative than useful, because you can find a remedy himself something else to do when it is deemed necessary. Whether one can call a bag with 20l volume as XL is probably a decision of Marketing - There are smaller and larger bags. The side pockets with zipper are not fake but at the expense of perception space, they are also so small that you can possibly accommodate the bicycle key and repair kit there, that was it however already. Whether the seams must keep permanent yet to be seen, at the M-Wave bag they do not know why I'm skeptical, but for the price, the bag is otherwise fine. Important to know is just that these things are meant to permanently remain on the bike, who wants to stow backpack and jacket in there is well served.
