Bandit,
Quoted from the Hestra site
Outer material
Upper section made of wind and waterproof, breathable Hestra Triton/polyamide fabric. Proofed Army Leather goat palm.
Only the upper section(back of palm and cuffs) is waterproof in the sense that water will not soak through or leak through the seams. The leather section isn't waterproof in the usual sense of the word, that was my point.
With that said, mine didn't leak under skiing conditions but, like you found out also, did get soggy under warmer conditions. However my hands were still totally dry, snug & toasty all day despite that.
They are great gloves, more glove than I need at the moment bought as a long term investment after my first pair of gloves, two weeks use, gained a shredded index finger and palm from holding skis along the sharp edges.
