Yes ww, Hotlines are excellent suits. Probably one of the best suits I've ever had. I've been wearing 4/3s in 50 degree water for a while. The last couple of times I've ordered a suit I wanted hotline and they were out of my size so Ive had two quicksilver's (synchro plus last one, pretty good but no hotline) from cleanline and had them shipped where I was traveling. Cleanline folks are top notch, great prices. I got gloves last order a few months ago and man those help in cold.
