Very nice backpack. My 15.6" laptop fits perfectly (there is more room, I guess a 17" laptop might fit, but I am not sure). The material is very resistant.

Очень срочно перед отпуском был необходим рюкзак для транспортировки ноута, зеркалки и других гаджетов. Продавец отзывчивый, все сделал как надо, отправил на след.день. сомневался между 17 и 15,т.к. не хотелось баул таскать на спине, все упиралось в ноутбук,он здоровый,на 17.3 дюйма (emachines g640g). измерил ноут, по габаритам вроде должен войти.в итоге купил 15 рюкзак и гада, а что если не войдет..., мой 17.3 ноут влез туда без проблем, правда плотненько,зато не болтался) размер самый удачный. лямки удобные, на спине сидит хорошо. ручка массивная, не оторвется, проверено! на влагостойкость не проверял, но материал мне понравился,чем то напоминает прорезиненный. в итоге, ноут с зарядкой,зеркалка с 2 объективами, зарядки, пол литра воды шорты, пару футболок, конфетки,очки,большой блокнот, и всякая мелочь, все что надо поместилось! спасибо за оперативную доставку, очень выручили!

Хороший большой рюкзак размер 17 дюймов. Пошив хороших, материал приятный на ощупь не знаю как будет спасать от воды, молнии плотные. Большой мягкий отсек самое оно для 17 дюймовых ноутбуков у меня там легкостью поместились тетради формата А4. Средний с нескольким карманами в нутри так же есть кабель для подключения повербанка, кабель можно спрятать в кармашек. Между большим и средним отсеком есть маленький кармашек из которого легко достать документы или телефон.Так же имеется маленький карман в который я бросил пенал.Так же по бокам по одному карману которые делятся на отсеки. Регулировка лямок легкая сами лямки прочные, так же на тыльной стороне есть карман в который можно положить что то ценное что бы точно не украли. Рюкзак пришел за 22 дня в Прагу из Китая, + подарок коврик.Thank you, Kingston!

Обалденный рюкзак, только кармашков меньше чем того хотелось-бы, при моем росте 180 идеально ! Хорошо работает утягивающая система, не часто такое встретишь. Качественно сшит, действительно водонепроницаем, молнии качественные, главное их смазывать, удобная ручка для носки в руках. Использую без ноутбука, поэтому хотелось-бы внутри чуть побольше кармашков, но пока и так сойдет. Повер-банка марки Pisen на 20 000Mah едва-едва, но все-таки влезла в боковой карман специально предназначенный для размещения Powerbank-а ;-) ! всем настоятельно рекомендую к приобретению данный рюкзак !
