Hi Charlie , we sell a lot of waders mostly hyelastic PVC which is 70 denier or 210 denier which is better quality . The PVC type is preferred by the whitebaiters because the,y pull their nets onto their legs to scoop out their riggiliy bounty . If you end up with neoprene I would suggest that you wear a apron with a cut up the middle and strap them on like chaps. I personally use breathables for Surfcasting with a belt . Like all waders your under layer is important high quality polypropylene type to wick moister away from your skin.
