The Alpiniste :

This is an updated take on the classic Karrimor Alpiniste series, from the Whillans to the Haston packs of the 60's & 70's. They ran 55-65 liters in volume. Features include a closed-cell foam padded back(removable for use as a bivy pad), double layer crampon patch, and a zip pocket in the lid. Fabric will be the original  11 oz Cordura nylon in classic Purple or the pre-Haston model in red.  Tall packs are custom fitted.
