If you prefer natural fillings, then goosedown is the one for you. Durable and naturally breathable, goosedown provides an ultra light covering, whilst not losing any warmth. While goosedown is the lightest and most luxurious of all the fillings, its not always suitable for those with allergies. The soft feathers can irritate asthma sufferers.
Synthetic fillings such as cotton touch, spundown, and perfect balance offer the advantage of being machine washable and equally comfortable and warm.
