They are in like new condition. I wear 32x30 and these fit great. I have pretty big legs from walking a lot and riding bikes.
The cuben/down pants are discussed in this thread:
Some lucky BPL'er is now the proud owner of the world's lightest down pants! These are made from 0.51oz cuben fiber, with 3oz of 900 fill down.
The weight is 141.6 grams (4.99 oz) without the stuffsack. With the stuffsack, they are 5.11 oz.
So, this means that 60.1% of the weight is down!
