My Everything Bag
I have too many duffel bags, I know it, I admit it. Most end up taking up space in a closet, but this one I use constantly. During winter, I use it to haul stuff up and down the mountain every day...food, clean/dirty base layers, chargers, etc. Off-season I travel a lot, and now that luggage costs, it's my carry-on that fits everything I [really] need. It has also been used as a gym bag, overnight bag, long weekend trip bag, throw in the back because it'll keep stuff dry bag, to name a few. Incredibly durable for the amount of stress it has gone through. Carries heavy loads, I've put 35+lb in it. I never worry about it breaking or tearing or leaking or being anything other than reliable.
