Handig, cool en stevig camera tas

Mijn zoon heeft vorige jaar cameratas in zwarte kleur gekregen en nu in sand beige kleur. Hij is tevreden met deze tas, hij gebruikt voor zijn werk als photograf. Alles kan mee in één tas heel handig. Dus deze cameratas gaat mee door hele land en buitenland waar hij fotoshoot heeft

Fantastische rugzak

Ik gebruik hem voor mijn sport door de rolltop kan er niets invallen. makkelijk juiste vorm voor op de schouder. E hij kan op mijn koffer!

Rolltop Rugzak Pro

heel nice

Eindelijk een tas waarin je niet hoeft te proppen. Schoenen in het aparte vak, laptop erin en klaar. Dit is echt zo’n ‘gewoon goed geregeld’ product.

onwijs praktisch de underseater.

Wat voor mij vooral top is: deze tas past écht onder de stoel in het vliegtuig. Ik vlieg veel met Transavia en KLM en elke keer was het gezeik met handbagage. Nu gewoon geen stress meer. De afmeting is perfect. Het ingebouwde tech-vak gebruik ik voor adapters en m’n muis. Hij is niet superdiep, maar juist daardoor blijft alles overzichtelijk. Kwaliteit voelt eerlijk gezegd duurder dan de prijs.

prachtige tas

ik ben super blij met mijn Weekender. Hij is ruim genoeg voor een weekendtrip én het laptopvak is ideaal. De onderkant voor schoenen is ook top want m’n gymschoenen blijven netjes apart. Kleur Ivory staat erg clean. Zou ’m zeker aanraden 5/5

Goede kwaliteit

Heel erg blij met deze tas, past veel in en is van zware kwaliteit!
