That isn't as heavy as I thought they might be. Do you happen to know the volume?

My standard for weight is if they are heavier than mine they are heavy and if they are lighter than mine they are light

Actually it might make sense to think of pannier weight in terms of total gear weight including the panniers. I figure that mine are between about 16 and 18% of the total gear weight (assuming 30-35 pounds total gear without food or water, but including panniers). Since 16-18% seems like a lot to me so I really don't want to go heavier.

I don't consider myself a weight weenie, but an additional 2-3 pounds is a big deal to me. I try to get down to 30 pounds and sometimes settle for 35 That said it may be a non issue for others.

Just as a frame of reference... My cheap Nashbar waterproofs are as follows:
Front 1056 cubic inches and 2 pounds 6 ounce (for the pair in both cases)
Rear 2310 cubic inches and 4 pounds (again for the pair in both cases)
