High performance roof underlayments

Help me out ….
Need the names of some High performance roofing underlayments.
Job may sit through this winter without final roofing applied.
Cold, snow, not much rain.
Location is a 6 hour drive from home and I will need to pick materials up locally there so I need several brand names to start my search of local suppliers there.
Thanks !

Most of the asphalt shingle manufacturers have a house brand as well.
The only one I know to stay away from is the GAF product. It "breathes" air out and water in.

There's another one called "Sharkskin". Only saw it once.copper p0rn
Was just walking around in the rain on a 7.5/12 roof today on REX. Stuck to it like crazy. I'm off RoofTopGuard. Don't like the way it can ball up under your foot on steeper pitches. Tiitanium works pretty well in the rain too.

Well, let me tell you about Titanium UDL.
I'm a DIY, which means any project takes me 10 times as long to do... unless it's the first time I've done it, them maybe it's closer to 50 times longer.
Anyway, I redid my garage roof and part of the main roof of my house. An add on 2nd story over a porch, along with a super low slope dormer created a roof rot situation that needed fixing. After I sheathed the garage, i used the Titanium UDL. Since I didn't want that weird low slope dormer, I instead created a new angled peak where the old one was so I could have real valleys instead of a flat roof. No, I'm probably not explaining this well - short story was that it was complicated.
Lots of time went into that rework, like MONTHS, and I was walking over that Titanium UDL with boots, moving stuff across, under the strong SoCal sun... no problems at all.
...except when the evening condensation would form on the roof, then it could be a little slick even with the built in traction. Heck, everything is slick with water droplets forming on it!
