I have some Eco Bumbles on clearance. They have flaws on the fleece or toweling or both. Some may have an additional layer stitched in as they may have started life intending to be a bumble until I noticed a flaw and turned them into an eco bumble for clearance. 

Eco bumbles may be made from white toweling, or from natural or white bamboo.

Details of eco bumble are below ...

The Eco Bumble is a great economy version the 'Bumble'. This nappy is here to make cloth nappying affordable for everyone with the added bonus of drying in a flash! The nappy is a btp nippa nappy. It is made of one layer Terry and one layer fleece with a pouch in which you put the absorbancy. So basically grab an Eco Bumble, chop up and old towel and away you go! No more pricey nappy systems or fancy poppering. You can use what you like for absorbency from posh fancy boosters to your nans old tea-towel whatever comes to hand!

To use BTP you simply fold down the front to suitable size.
