The bag was purchased in Feb of last year. At least I'm pretty sure that was when... I might have the receipt to confirm, but I will have to dig through some paperwork.
Just as an FYI to you (or anyone else) another member PM'd me last night asking about the length of the bag for his GF who is 5'-5. I asked my wife to climb in and lay flat; she's 5'-2. I then measured the unused length in the footbox which, to my surprise, was around 5 or 6 inches. I just compared this against her Ultralight (also 5'-6 size), and that bag is 2-3 inches shorter than her Alpinlight. This prompted me to weight the bag and I found it to be 31.5 oz, which is about 2.5oz over spec. I'm not sure if there is some manufacturing variance or what is up here.
It would appear that this bag can accommodate someone as tall as 5'-8. I'm pretty confident about my measuring skills, but I'm not making any guarantee here. For someone 5'-7 to 5'-8 you *may* be able to sneak into this bag comfortably... but if it doesn't work out you'll have to turn to the gear swap, not me :)
