thanks for finding out about this (and thanks to Hilltrek for going with it);
I initially thought £110 a bit steep for this poncho, but if you compare it to Hilltreks own 'Braemar Single Ventile® Windshirt' (also £110, which is also cheaper than at least one other rival companies version), I suppose the price is pretty fair as the poncho is going to be a limited run and they are going to be making up new patterns etc. from scratch.
The proposed poncho is also going to be double layered on the hood and shoulders. I can imagine there may be as much work to do to produce a Ventile poncho as a single skin jacket.
The results of the test of the preliminary item will be the decider for me.
