Stumbled onto REI.com this morning and saw that they are having a pretty good Cyber Monday sale. Of the items on sale is their REI Co-Op Trail 40 Liter Backpack. Available in multiple sizes and colors (mens & womens).
I've been eyeing this for a while and this is the lowest price seen. Reviews are pretty good on this bag, great for hiking & travel. Got myself a black one, and teal (pacific blue) for the spouse.
Free shipping if over $50 or free ship-to-store.
