Would a 154 board with bindings, boots, and 4 days of clothes in the 175 bag be over 50 pounds?

I wrote a review and answered a few questions. In my reviews list what I brought in my bag, and I never had to pay over charges on any of my trips. So no, it prob won't. But I dont know how heavy your clothes would be, what size of boot you have or even the make of your board. It really depends on all of that lol. Just read my reviews and you can make the decision. Cheers!
