Heathyr Quinnwrote a review of DAKINE EQ 51L Duffel Bag - Women's - 3100cu in on December 12, 2012
Familiarity: I've used it once or twice and have initial impressions
I got this bag to transport my snow sports gear. To give you an idea of the size of the medium bag, I can easily fit my ski boots, snowboard boots,goggles case, and snowboarding helmet (in the end pocket) all in the bag!
Also, if I was going out of town for more than a week, I wouldn't rely only on this bag (I'd take a second, or use the large eq bag).
