Yes it's magical stuff! I got through about 1/2 pack on the CF. Pat when through a whole pack by Ponferrada! But thankfully my military logistics training came in handy, as supplies were dwindling I had a 'resupply' mailed from New Zealand 7 days before, waiting for us at Villafranca del Bierzo. Wonderful service from those folks in NZ. https://www.hikerswool.co.nz/
