Used this ruck on a 150 mile hike through the mountains…

Rating: rated 5 of 5 stars

Used this ruck on a 150 mile hike through the mountains in Greece in December and January. It snowed & rained throughout our trip and everything stayed dry!

I was a bit skeptical about the comfort this ruck would give for such a long trip through the backcountry. I was pleasantly surprised at how comfortable it really was the entire time. The size ended up being perfect for what we were doing. We spread loaded food, water and fuel for 5-6 days among us and would venture into various towns along the way for a resupply.

Go buy it! Never leave without it! Great piece of kit!
