I have a 3mil Xcel bamboo lined hood with drawstring and I love it. I have front-zip wetsuit and the hood had two layers, one to go under the neckpiece and then another layer to go on top of the neckpiece. Minimal flushing and very comfy. If you are surfing in the northeast then you might want a hood with a thermo layer attached to help keep ya warm!
before i got my drylock with attached hood i used my 4/3 drylock with 2mm wetsuit hood with bill. It had thermobamboo heat retaining lining made with bamboo charcoal infused fibers. It kept me warm all winter long. If u dnt have a hooded wetsuit then this is good. If you want something that wont flush as bad and easier to use. I would get the Xcel polypro hooded vest.
5mm hyperflex bibbed hood. 20 bucks ish. I wear mine with my 4/3 when I dont wear my 5/4/3. Warm as it gets. Super comfortable and no chin fatigue. No water in unless you get really trashed underwater.
