Which would you recommend?Is there another brand out that's better?Thanks

I own both and would definitely recommend the x scent for the early season warm weather. Its soooo comfortable and keeps you scent free(and cheaper). Wear the under armour when it starts to get really cold in late season

For warmth Underarmour is excellent. However, I don't think they claim to suppress scent.

I agree..I used under armour last year when it was really chilly and it worked great..

Correct, UnderArmour is not scent containment or eliminating clothing.

I have a set of ScentLok Base Slayers and then a set of ScentBlocker over it, then my normal layers of camo.

I have worn both in the past few years. I like the xscent due mainly to price.
Good Hunting.
