Just got back from 8 days in Switzerland skiing under the matterhorn. I only took this 50L bag and a small convenience carry on and it was AWESOME!! I have two pretty intense knee braces and situated them to hug my boots in the boot compartment. I placed my toiletry bag on the top part of the boot compartment since I had extra room on top of my boots in the larger bag. The goggles were tight in the compartment but it still work and the padding was nice on top of placing my lenses in a beanie. I placed all my clothes and base layers in the larger mesh compartment on the left.
I flew British Airways there and American Airlines back. Neither airline gave me a hard time and I just had to unbuckle the helmet cradle and kinda situate it over the corner of the bag to make it fit overhead. I had it packed to the brim and little squish also got it into in the regular planes too. I had to open it at London Heathrow security and it was quick and easy.
Excited to try it locally, but this is a huge winner for international trips trying to one bag it.
