Black Diamond's Soloist Finger Mitten features a BDry waterproof insert, high loft fleece, and PrimaLoft Gold insulation inside the removable liner. Gold synthetic insulation is PrimaLoft's latest innovative solution for lightweight warmth. It feels as soft and compressible as down, and it features permanent water resistant protection. Because this heavyweight insulation is inside the removable liner, you can wear the Soloist Finger on summer alpine climbs as well as winter ski sessions. This glove also features a goat leather palm for a good grip, Kevlar stitching for durable reinforcement, and a split index finger for better dexterity.
