GR2 Robic Ripstop Nylon from GORUCK review

Here's a few details about the robic..
TOUGH, LIGHTWEIGHT, EASY TO CLEAN
This GR2 is built out of 420D ROBIC®
Ripstop Nylon. What that means for performance is that it's super water-resistant and ultra-lightweight. The ripstop grid pattern increases tear strength for an overall better strength-to-weight ratio and it's got a special waterproof coating that's designed to last longer.
