Some of the SA spearos wear gardening gloves. Probably warmer out there. I often have a quick look over the gardening gloves in our local village hardware store, they have quite an impressive selection these days, inc. close-fitting stretch waterproof gloves. However, I still use neoprene spearo gloves.
I like the shape & fit of Beuchat gloves best. I prefer the older, thicker versions over the new, colder, tight, 2mm super-stretch models. But I also have a pair of Mares gloves that match my camo wetsuit - I bought the largest size they produce (size M-L I think) but they are a bit too small/tight - and my hands are only a normal Large in size - and don't fit as well to my palm as the Beuchats.
I bought my son some Picasso socks and gloves - their sizes are well off (v. small for the stated size), which is frustrating for all concerned. Not a fan of Picasso gear.
