What is a good rain suit for around 100 bucks that will keep you mostly dry till I save enough to buy a gore tex suit

That's tough. The most expensive Frog Togs you can afford or look at a used set on some forums.

Toadz Skins by Frog Toggs.  Get the bibs and you will be dry for at least 6 hours.  (tested in a tropical storm last year)

I live in South Florida and Frog Toggs are the best here because they are not that hot to wear.  They are priced well, very lite weight, water proof, and come in all sizes, including Jumbo and super Jumbo.  If you fish in the heat, these are the way to go.

Keep an eye on the Cabelas Bargain Cave. 

 

Their Guide Wear is great gear and is often available very reasonably.

Academy has a nice set of bibbs and rain jacket for 140 they've gotten a ton of good reviews

Toadz Skins by Frog Toggs is what I use.  Works really well.

Frog toggs from walmart works fine 29$

You choose your rain suit based on the ambient temperature.  Early spring, late fall, 45 degree temps & below, long boat rides where wind chill gets involved - Guide Wear is the way to go.  (Or the BPS 100 MPH suit that is similar, and I am sure that there are other suits that are of similar quality)  In more moderate temperatures, you can go with a lighter weight gore tex suit.  For summer showers, I don't think you can beat Frog Toggs, just because they're so lightweight that they don't get uncomfortable.

 

Frog Toggs do work in colder weather as long as you've got appropriate layers underneath.  

 I've got a 300 weight polar fleece jogging suit and with long underwear and that suit and the Frog Togg outer layer, I've been out in some pretty chilly weather and been fine.  If I wore those same layers underneath my Guide Wear, I'd be so sweaty I couldn't stand it.

Thanks yall for all the replies probably gonna get some frog toggs
