GORUCK GR0 as in GR Zero.
If the GR1 was a tad too big and the Radio Ruck wasn't really what you wanted, GORUCK has now the new GR0. Exactly proportionate to GR1, only 5 liters smaller. Fitwise, if you’re under 6’ tall, GR0. Over 6’ tall, GR1. GR0 has all the same features as GR1, including 3 rows of MOLLE webbing and compatibility with the GR1 Field Pocket.
I'm getting one.
