The popular Vinyasa Scarf has become more "unisex" over the years and more males are wearing them. Thanks to the Lululemon Park Meadows Store, they are modelling them on dudes.
The top one is the mini check pique white/black
(I have the one from last year which is darker)
The bottom is the Pigment Blue Stripe
Here is the video on how to wear it...
(I wish they made one more styled for guys)
