My boyfriend uses a lot of deoderant and we purchase it often. He prefers the Old SPice brand to any other on the shelf currently. According him they offer better protection then most everything else. The last deoderant purchase I made for him was a twin pack of Old Spice High Endurance in Pure Sport scent. This is not normally the specific one he we buy but it was a twin pack and on sale so we gave it a shot.
He has had no complaints with this product other then it is solid stick and he normally uses clear application gel.
As far as protection goes he has never complained and I have not noticed it not working. I would be the first to tell I assure you. Even after being outside in the hot sun all day he comes in sweaty. but there is no smell what so ever. In fact, this deoderant smells pretty good actually.
I'd snatch this one up the next time you see it and give it a try especially if it is on sale like I purchased it. It was a good $3.00 spent.
