Very disappointing comfort.
Really sorry tk write, but the Elqui 18l back pack has been a disappointment. Worn on z couple of hikes and the shoulder straps are too thick and very uncomfortable on the shoulders. Not a technical back pack that the price and descriptions suggested. Would have returned but unfortunately I have used it twice. I won't be buying Cotopaxi again. However happy to trial for your testing should you need feedback on your future designs.
I love the colour and the uniqueness of the product and bring recycled but it's not fit for purpose.
