>>1774383 (OP)Foam grips, sponge foam kind, are the true 90's patrician choice for mountain bikes. Back then they came in black and black, striped pic related ones are similar. The new smooth silicone foam I find slimy reminds me of degrading rubber grips.
Big thing about foam grips is they are warm immediately. A lot of people wear gloves these days and don't care as much as previously. Downside - wear out kind of fast.
