Komperdell is advertising the "first seamless bonded" glove.

They have several models on their website. There is no info on the weight although they don't look ultralight. However, I have yet to find a glove that doesn't leak through the seams. When skiing on multi-day trips, I take two pair a gloves and switch off every other day. This could be a significant advancement or perhaps marketing hype.
