Related Questions and Answers

Q: 1. What length avalanche poles will fit in this backpack. IS there room for an avalanche shovel?

A: There is no limit to the length of a pole other than what you are comfortable with carrying. A pole or tripod would be external to the backpack as shown in this photo: https://bit.ly/2X70YlM However using an extremely long pole could interfere with your ability to walk but a taller person would be able to handle a longer pole than a shorter person. It would be more comfortable using a pole, tripod or shovel that is not much longer than 21 inches,

Q: 4. Can I carry a D5 with 200-400mm f/4 VR attached with the hood inverted, a Nikon AF-D ED 80-200mm f/2.8 and a Sigma 24-70 2.8 Ex Dg in this model or should I upgrade to the 450 AW II? Many thanks

A: You will be best served with a larger/taller bag: the combined length of the D5 and the 200-400mm lens is about 18" and the 350 AW II has an interior camera compartment measuring 15.4". The 450 AW II's camera compartment measures 16.5", which is actually still a bit short to be ideal. If you remove the lens from the camera body, you should be able to fit everything into the smaller 350 AW II bag.
