I'll never go back to neoprene. Ever. They suck. They freeze and you can't move. I had a pair of Rogers insulated breathables for a year. They were comfortable and warm. They didn't leak but I hated the boots and the bulkiness. I think you could put some soles in the boots and make them better. That same summer, I had someone sell me some used Sitka zips. They had been wore a season and was shipped back to Sitka for maintenance. I paid about half of regular price but they were used. I've worn them for a season and a half and I love em. Its super easy to layer under them and I've yet to get cold. They are much more slim fitting than my Rogers. I haven't had a leak yet but its probably coming. If that happens, I'll send them back to Sitka for repairs. I don't think I would buy them brand new at retail price because that's a huge chunk of change. But I'd probably pay $6-700 when you find them on sale. The boot is what makes them great. Very comfortable.
