Do different tariffs for men's and women's gloves violate the Equal Protection Clause?

[jure.toplak at uni-mb.si]

What about bars and nightclubs with different entrance fees for men and
women? 
Just returned from Vegas were most of the nightclubs and launges in
Vegas have different prices for different guests based on their gender
(for example, there is a free entrance for women and 20 dollar charge
for men, or the charge for women is 5 dollars and for men it is 30).
There was also one that offered "free champaign for women but not for
men".

Totes-Isotoner Corp. v. United States (Fed. Cir. Feb. 5)
(http://www.cafc.uscourts.gov/opinions/09-1113.pdf), says no, though one
judge took a different approach from the other two.  Any thoughts on
what the right analysis should be?
 
By the way, I take it that we’d agree that stores that specialize
in men’s clothes or in women’s clothes shouldn’t be
seen as public accommodations that illegally discriminate based on sex
(in those states whose public accommodations law cover retail stores)
generally.  But should that be because this isn’t really sex
discrimination, or because the statutes ought to have, or ought to be
read as having, an exception for such behavior?
