The suspension system can really handle a heavy load. I had around 60+ lbs in mine and was able to navigate the hillsides with relative ease. The only real problem i had was the hip suspension belt tends to tilt the load to either side if you are on rough terrain. Rain and this backpack are not friends but it can be fixed with a garbage bag or whatever else u want to throw around it. very roomy and comfortable pack otherwise. my first night using it i had some scrapes and the material as light and thin as it is in some areas didn't rip or tear. But overall comfort and feel this pack is amazing.
pro's- a comfortable sturdy pack, the hipbelt is great on a normal hike or trail, can handle a heavy load and put it where it needs to be.
con's- Price. zippers are a little leaky in stormy weather, tends to tilt if your load is too heavy due to the swivel in hip belt, suspension system can be a bit tricky to get just right.
