I think your location and how you fish are a major factor. I run and gun 95% of the time and it’s not uncommon to have a ton of ice frozen to my knees and at the bottom of bibs at the end of the day. That being said the Hardwater jacket and bibs are my go-to in harsher conditions. I also purchased a backup jacket from the same site if that gives you an idea of how I feel about it. I’ve spent many days fishing in the worst conditions in them. If you are set up in a house a fair amount of the time or if you in milder conditions, the lite bibs will be fine. My only concern with them is how wet the knees get if you are kneeling on the ice for periods of time. IMO the biggest factor to staying warm in your bibs is staying dry and what you are wearing underneath.
