I purchased my first silk liner in Leon from decathlon it was very reasonably priced, I have used it for several caminos and loved it. I have just ordered a second from Vietnam on eBay $20 delivered
sounds promising , XL wide model with pillow pocket and double stitching, it is my plan to take both on my next Camino, on colder nights I will double bag. All up weight for two silk liners aprox 300 gram 1/3 my sleeping bag. I will test the warmth of the double bag on the next cold Melbourne autumn night .
