Reviews

Very happy with my Goruck.

"This is the best backpack I ever have owned. Very robust and straightforward design. The Quality is on an other level. Very comfortable to wear too. The padding is great. No abrasions. My GR3 35 L is a loyal travel buddy by know. The clamshell opening in combination with travelcubes make packing a breeze. Very very satisfied."

— Johan W. (5/5)

Sehr robuster Rucksack

"Ein sehr robuster Rucksack, der viel aushält. Er ist kein Leichtgewicht und der Preis auch nicht. Trotzdem würde ich den Rucksack empfehlen!"

— Karl O. (5/5)

New GR3

"I am still trying to decide whether to keep the bag, because I may need a hip belt. That said, the quality of the construction, simplicity of the organization, very sturdy lap top compartment, and available packing space are all just what I was looking for."

— Thomas M. (4/5)

Would buy a second one.

"I just recently put to use my GR3 both for short travel and for an unexpected use as a gear bag carrying my electronics, mics and cables to play a show as a drummer. Along with pockets and pouches it all went great. Those 45 L sure go fast and the bag fills up quick. Additional capacity would be appreciated in a larger version."

— Rodrigo M. (5/5)

GR3

"Just took a week long trip and this was a perfect fit for one bag travel. Solidly made like all GoRuck bags! Especially like the top pocket for tucking keys, wallet and phone when going thru TSA security. I also have a Rucker 4. 0 for the last 2-1/2 years which I use constistently and shows no wear. Expecting the same from this bag!"

— John N. (5/5)

"Cavernous!! No issues on the plane. Will last forever."
