Reef Hawg, what temperatures do you call warm weather? I wear my Guide Series from Cabelas most of the time. At least even when it is in the 70’s and below. That I believe is the best stuff on the market hands down. As Buckshot says below, there is un insulated guidewear. Nothing beats the price of staying dry and out on the water longer because of it!
Otherwise I have a pair of Frogg Toggs for when it really gets warm. These are really lightweight and surpisingly keep the water out and if you are just fishing with them, they seem durable enough for that. I just picked up a pair from Minnkota’s (Trolling Motor) website FROGG TOGGS that are Gray for the Girlfriend. I have only had mine 2 years but they have taken some abuse and seem to keep the water out well. They do not seem like much when you pick them up, but they can handle fishing activities. Good Luck
