You might know it already, but almost all of the gear I took on my trip was from REI. I was happy with almost everything I had with me, and the few products that wore out over the six months I used them were replaced or refunded (with cash) by REI with no questions asked.
REI is having their anniversary sale right now, and it goes until Sunday.
Hop on over to their site for some incredible savings. I have already been to the store more than once this week to stock up on gear for Alaska.
