I'll try to make this quick for those who know and those who think they know...

there are alot of waterproof materials out there. Most known woudl be Gortex.

I'll give you 2 items to compare and they are both Gortex.

Browning Pro Series HydroFleece and Cabelas MTO50.

Start with Cabelas:
Very nice rain gear that is light weight and comfortable and has good storage pockets and it packs into a small package for rain gear.
Sucks - Cuz it only last 3 years before it failed. Cabelas replaced it for me, so this year will be 2nd year, so we'll see.

Browning:
AWESOME STUFF.. their old gear with Gortex was amazing.
I sat in a stand during a all day rain pour and the seat filled with water and i sat in it all day and i was never wet.
REASON older browning is better then new, is because its Gortex.


Not all Gortex is the same.

Same reason people think MILSPEC is the best. The USMC suit i had was junk. Failed 2nd year.
Because they had the minimal requirments as possible. What the wind rating(PSI) before it fails, etc.


What matters is the spec the manufacturer has Gortex make it to. How many layers of Gortex fabric, the PSI rating on fabric before pentetration. remember you buy junk you get junk..
