I have 3 suits also. Started with Scent-lok then Scent Blocker. Then 3 weeks ago I bought the new Savannah series of Sent-lok because it is always so hot to begin the season. I plan on using the Savannah series to start the season then as it cools down add the Scent Blocker over it and I should have good coverage and warmth till it gets really cold. I can' t tell that one works better than the other though.
