Fibre-pile Insulation:
Polyester fibre-pile pile. It is warm to the touch, it is equally warm when wet, and as the fibres do not absorb water, for insulating material it dries very quickly. It also resists mould - which is an issue with the inevitable build up of condensation.
YKK full-length burstable zips
All zips on our bags are YKK coil for their strength and reliability. The main zips are YKK No10 coil with non-lock zippers.
Poly-cotton:
We use polycotton for the pillowcase in the original Ocean Sleepwear sleeping bag. It is comfortable, and can be quickly washed and dried, stopping the build up of salt from wet hair.
