When I first grabbed on to these jugs I thought, 1" thick pancakes. The minimalist design allows for a deep 1-1/2" to 2-1/2" deep incut. The incut angle is around 45-degrees. That means this is a very easy jug on vertical up to semi-steep terrain. On a 45-degree angle, These would be little ledges. The width of 7"+ leaves room for both hands. They are giant for just one hand of any size.
