I got to try on the Nulux Speed Wunder Tights and Energy Bra today and really liked them. People seemed to have been at a loss to explain exactly how the Nulux fabric feels but I thought they felt similar to the super silky, stretchy luxtreme that is found on wee space luxtreme bottoms except thicker. I don't think the material feels at all like the Nulu that is found in the Aligns - it's pure luxtreme, in a super silky and stretchy form. I have read many reports of the Marbled Mix colorway being sheer but they had good coverage for me and I made sure to check in a few of the mirrors out on the floor. I was wearing nude underwear but I never saw the edges or outline of my underwear. The ultimate test would be to take them home and check in outside light but I've definitely been able to tell sheerness in the changing room mirrors before. The material was nicely matte and provided good coverage for cellulite, too. I was tempted to get them since they felt really nice and I love trying new fabrics but I just don't care for the beige (or pale gray?) in this print, which makes them seem a bit dingy and throws me for a loop when it comes to pairing with tops. For $128 I really need to love the print to pay that kind of money. I would definitely considering picking them up at an attractive markdown price.
