I don't think it really matters too much...the changes are very minimal.
I got this from the My Natural Baby blog:
We are pleased to introduce the manduca NewStyle which will have the following new features:
- The lining, hood and logo are now colour-coordinated to match the body of the carrier.
- The well-established, universal pink logo will be replaced by a matching, embroidered version similar to the ones you know from the manduca LimitedEditions.
- The range of standard colours will be extended by the introduction of NewStyle Navy – a classy dark blue.
- The ‘natural’ manduca will be given a marvelous sand-coloured hue and hence be renamed ‘sand’.
- The connection strap now has its buckle right in the middle, which allows for easier handling.
- The stitching and shape of the shoulder straps are slightly altered for a maximum of comfort.
- Just like with the Manduca LimitedEditions, the exterior back pocket will be dropped – with this Wickelkinder GmbH complies with their customers’ wishes as well as their decision to avoid any possible pressure to baby’s back. In any case, small and/or valuable items are easier to reach and safer when worn closer to the body (e.g. in a manduca front pouch).
