WHAT OUR CUSTOMERS ARE SAYING

The backpack is quite amazing. Exactly has I thought, plus it shipped really fast. I'd order from this website again. I'm going to Europe this summer for 3 weeks and the 40L is exactly what I need. The fact that it opens like a suitcase is the greatest thing ever. You can reach for anything really quickly. I would have loved a side pocket on the lowest strap for a bootle of water or something but overall this bag is #1 !!!!

KATHERINE G. W.

This was my first order from Outter Limits, and I am very impressed with its pricing, customer service, and friendly Saskatchewan attitude. The order was processed immediately, shipped promptly, and delivered early to the West Coast. Thank you for the superb service. You have my highest recommendation..
