How does this compare to the tnf base camp? What weight is the large?

Any experience with the zippers, are they smooth or snaggy?

I have both. I have the Stoic in XL and the North Face in Large. I like the North Face better. The straps are better, it is MUCH more durable, daisy chains are nice, the mesh pocket in the inside of the top flap is nice too. But- the Stoic is larger volume, packs down small, and is light. So I travel with both. I end up putting the Stoic inside the North Face to bring back goodies from afar. If you can score the bags on Steep and Cheap or Tramdock, the price makes it well worth picking up. But again, if it were between the two, and the price were the same, thumbs up to the North Face. NOTE: I just used this bag for air travel for the first time, and the waterproof coating has peeled off on several places. This is the first major trip for this bag, and not a difficult one at that (MT to South America, with 2 stops). After seeing this, I cannot recommend this bag. It still might be OK if you just need an extra duffel for lighter duty, or maybe a spare bag to chuck around, but don't count on it for long term durability or waterproofness. Ger the North Face Basecamp or Patagonia Black Hole bag.

they are a large #10 waterproof zipper that is pretty smooth. they are a little stiff because of the waterproofness, but i would not say snaggy..
