Under Armour gear is overpriced IMO. You can get similar technical gear for a bit less. Of course,the Mack Daddy set is NOT a "bit less" set either. That is top end in terms of price.
Is this for bow or gun hunting? Waterproof? I have the Cabelas Supreme Elite Fleece set that I got 50% off, its great for gun hunting, wear the bibs for gun and bow, but the jacket is too bulky for bow. Also have Scentblocker Road Trips fleece set which is mid-weight, use that jacket w/ a heavy fleece under it for late season.
Cabelas has some of their MT050 Whitetail Extreme series on sale. That is good stuff too.
