I have a used Golite Infinity, size L. The color is solid black, max volume around 3300ci. The weight on my scale is 39.8oz = 31oz body + 5.7oz framesheet + 3.1oz lid.
The bottom of mine has a two small holes, each about 5mm wide. There is also a narrow slit of 1cm length and some general use apparent on the bottom. Everything else looks and functions just fine.
I bought it used about 6-8 months ago. It really is wonderfully comfortable, I just don't carry enough weight to keep it.
New models are on closeout for $130. For you, special price: $50 sends it to your house.
