Purflo SleepSac Bunny Specification.. (Tog 1 / 55 cm / 0 to 3 Months) The brand new baby sleep bag, the PurFlo SleepSac, is equally revolutionary. Developed in partnership with experts, the PurFlo SleepSac provides a totally natural, allergy reducing sleeping environment for babies. Why use sleeping bags? Suitable for babies from birth, the PurFlo SleepSac has a 100% cotton outer whilst its silky soft lining is made from Bamboo Dream, a fabric which is made entirely from bamboo fibres. This gives the SleepSac anti-bacterial properties like no other sleeping bag, and is exclusive to PurFlo. The filling used in the SleepSac contains Amicor Pure, an intelligent fibre proven to combat the build up of bacteria, fungi and allergies, especially the house dust mite, which is known to aggravate allergies such as asthma and eczema in babies. PurFlo SleepSacs are made to the highest technical specification available. This, added to its attractive look and exceptionally comfortable feel against your baby, makes the PurFlo SleepSac the best and most anti-allergenic sleeping bag on the market today.
