The Activa Zip Front Bra costs about $38, while the Enell sports bra is about $60. From my comparison tests, the bras are very similar so why pay twice as much? These three photos show wearing the Activa Ultratek Zip-Front Sports Bra in size E, which covers sizes 40DDD, 42D-42DD, 44D. I was pleased to find it fit true to size – I wear a 40DDD and the Activa size E fit me comfortably.
(Like the Enell sports bra, the Activa sports bra does not come in specific band/cup sizes. Rather, they come in sizes 1 – 8 and A – F respectively.)
As you can see, the zip-front, molded cup bra has real hold. It covers my back well, which I find very important for comfort (the more coverage across my back the less weight pulling on my shoulders).
The bra is constructed of Supplex/Lycra® – which to me feels like a firm, soft cotton. Apparently it has moisture wicking properties as well. Come to think of it, the last time I wore this bra was a blazing hot day and I didn’t have the sweating under my breasts that I usually get.
One interesting design feature is the three inside hook closures (one at the top and two at the bottom) that provide a back-up to the zipper. The hooks are easy to do up – in fact, often I’ll just zip up the bra and find that the hooks just automatically hook themselves.
The Activa Ultratek Zip-Front Sports Bra comes in these sizes:
A: 32DDD, 34C-34D, 36C
B: 34D-34DDD, 36D-36DD
C: 36DDD, 38C, 38D, 40C
D: 38DD-38DDD, 40D-40DD
E: 40DDD, 42D-42DD, 44D
F: 42DDD, 44D-44DDD, 46D
Note: Although the Activa Sports Bra was a complimentary sample provided at my request by the manufacturer, my review is an unbiased appraisal.
