These look like an improvement over their older versions, of which I have a couple. These are now 100% Merino, rather than a Merino blend, so should perform even better (but also require a little better care to reduce bobbling).
I've just ordered a couple more of the tops.
Icebreaker still make the best Merino kit that I've tried, but at 20% of the cost I'm more than happy with the Crane offerings!
