Clearance on the Original, XL, and Compact versions of this backpack. Sale price is $45 each, but there's an extra 10% off this price which will show after you've added it to your cart.
I don't know if they're any good, but I've ordered an Original one for myself to try out at this price.
They have some other interesting things on sale - make up $100 worth to get free shipping.
Is this the genuine product by XD-Design? A lot of replicas out there.
