Got my 10 peaks mount tuzo mitts mainly for using at hemel but I took them to Andorra a few ago and seriously don't know how I'd deal with having mitts or gloves without the C-zip now! haha. I must have unzipped and rezipped about 100 times a day, Me and my buddy were just cruising around the mountain with his camera and taking it in turns to film, it was so useful being able to get my hands in and out quickly and then to not have to hold hold gloved! bonus!!!
Heres a little edit he made of me from a fun afternoon in pas de la casa! (featuring my mitts) ;)
