There's another item I forgot to mention (I bet it won't be the last either) as I'm looking for a good way to carry them without damage in the pack. I try to carry 3 pair of spare lenses for my sunglasses. an extra pair of tinted, an amber pair and a clear pair. I've nearly learned the hard way how dangerous it can be moving through the bush in the middle of the night without eye protection. I've had laser surgery so it's extra important for me to protect my investment...the amber/yellow lenses also help with my twilight vision (it's not as good as it was before the surgery).

As a side note I always buy the same glasses from the MEC. When I break a pair, they can be replaced for about $30 and the old pair is then salvaged for future spare parts.
