They got back to me. Very quick reply and good customer service from them I've got to say. I'll adjust my shoulder straps as they advised below:
Hi John,
Many thanks for the additional information.
The pilling in your photos is generally caused by wear and tear and/or abrasion. Shoulders and the hip/lower back areas are where a lot of the load is concentrated and therefore where we might expect abrasion to occur.
Lightweight fabrics and durability don’t go together so on occasion you will get a piece of clothing that shows signs of pilling because the fabric has been rubbed by a more abrasive material. Back packs use harder wearing fabrics and so when these meet lightweight clothing, pilling can occur. The webbing on a backpack straps in particular can roughen up fabric or an unevenly loaded or adjusted pack can also exacerbate the problem, and in this instance there appears to be a gap between your shoulders and the backpack straps, so adjusting the straps a little could result in less movement less movement and therefore less abrasion between the straps and your clothing.
As you have noted the problem has not been present with your Gore-Tex jacket and this is likely due to it using a harder wearing face fabric, and I suspect therefore you would not have an issue with the Sprayway Torridon jacket either as this is uses 75D fabric.
I hope that helps but please come back to me if you have any other questions and I will be happy to help.
