Hi all, I think I just found a bargain on ebay with silk sleeping bag liners at £19 delivered from Vietnam.
100% PURE SILK
SIZE: 210 cm x 80 cm (84’’ x 32.8’’
WEIGHT: 110~120 gram – 4.2 oz (super lightweight)
From careful analysis of their feedback there's no negatives or neutral regarding their pure silk sleeping bag liners so I reckon they must be genuine, and at their advertised weight I reckon they must be 100% silk for sure.
