Picked up a TNF Verto a few weeks ago. Full-zip, hood, chest pocket. Weighs exactly 3 oz. in XL!, which is less than advertised for a medium.
I had been looking for a Montbell Tachyon or full-zip hoody, but MB no longer makes either and they do not appear to be available anywhere. I suspect that they had wear and tear problems with their ultralight fabric, because their new wind jacket has heavier fabric reinforcement at all wear points and weighs nearly twice what the older offering weighed.
The Verto is constructed of the newest Pertex Quantum, which is truly gossamer thin but claims to be much stronger than similar ultra thin ultra lightweight fabrics. Only time will tell if the Pertex holds up. Seems highly breathable, and treated with DWR. The only thing I don't like about the Verto is the elasticized cuffs, which are too loose to stop wind from blowing up the arms. I've taken to carrying two elastics in the pocket and putting them around the cuffs if a cold wind is blowing up the cuffs. Other than that, I'd rate as excellent.
