I'm a big fan of Dakine bags, and have been using an EQ duffel for years with no signs of wear, so I didn't think twice about getting this one for a trip to Snowbird with the lady. This bag is well padded, and definitely built to last.
We brought a 157cm board, 155cm skis, poles, and two pairs of boots. I don't remember her boot size, but I wear a 10.5 and we put a pair in each pocket. At this point we were right on the 50lb limit, so I couldn't add anything else without forking over a fortune in overweight fees. If weight wasn't a concern, we could have both put jackets, pants, baselayers, gloves, poles, goggles, and running gear for those cross training days. While it has room for everything, you'll end up with lots of wasted space because of the weight. If I had to do it again, I'd buy the low roller for the hardgoods, and supplement with carry-ons for everything else.
If you have status or a credit card that ups the weight limit, this would be a killer bag, otherwise go with something lighter.
