165cm if u plan on buying a bigger board in the near future otherwise 157.. my biggest board is 161 and i bought a 175cm bag with the intention of buying a bigger board soon but right now it kind of sags and flaps over when u pick it up at the front because theres no board or anything stiff in there to keep it rigid
Get a bag with wheels. You will regret it later, unless for some reason you enjoy lugging heavy bags around.
I second the Dakine Low Roller. Very good bag for basic needs and it'll fit a full set of snowboard gear inside it easily (boots, board, helmet etc) and even a second board if you pack it properly.
Pretty much the same bag but has wheels.. about what is the weight with everything packed? 35 lb? Maybe it does not seem all that much to me since my job involves lifting and moving stuff at least 5 hours a day.
Well typically you're going to fill it up with clothes and other things to keep everything packed nicely and padded in transport.
My bag usually weighs about 20 kg fully packed with a full set of gear and some clothes. You wouldn't be going past 23 kg in a lot of situations because otherwise airlines hit you with overweight fees.
Honestly the wheel thing is something people constantly regret when they cheap out on a board bag, but it's up to you if you're happy to put in the extra carry every time you travel. Just be aware that board bags can be very awkward to carry because they're quite long.
Personally I think the small extra amount of money for wheels on a bag you're going to use for a lifetime is easily worth the money.
i got the dakine high roller and its amazing. 175cm so fits everything i need in it. had to pay $75 for extra baggage weight but thats 3 boards, 2 bindings, 2 boots, helmet and a shit tonne of other gear. i just throw everything i use on the snow including thermals and outerwear into the board bag and then a suitcase just for the rest of my street clothes. dont mind paying $75 to ride BC pow 6 months of the year with well equipped gear
