If you dont like hoods, you just roll it down: you can either roll it down entirely or use it as a wind/cold air block for your neck which is what I do on cold windy days. I dont have any issues with it interfering with a helmet. The Proton can provide much more warmth than a Nano-air can. I own both but the new (80 gram) Proton is far more versatile and warmer when needed. Ill wear the nano air for warmer days where the proton is too warn (20*+ days) I always prefer a hooded version.
fwiw- a windshirt is not really useful if you are using it as a mid-layer with a hardshell. they are far less breathable (moisture transport) and will trap moisture. it defeats the purpose of wicking layers.
