Some brand name athletic clothes are a challenge to find at any discount (unless you buy them used on ebay or at your local consignment store). Activa carries lines like Prana, Patagonia, Lole, and Nike for 10-70% off retail. I found a brand new Prana top ($25 instead of the $40 retail) on their site for less than the same top on ebay used! They even have very sweet deal right now if you want to stock up on your yoga or hiking wear; buy four items and the lowest priced item is yours for only $1.00, just use code FZ190001 at checkout.
You can sort your searches by category, size, price, color, or brand, so they really do try to customize your shopping experience. For those who are style challenged, they even have an outfit tab which puts together a coordinated outfit for you whether you are lounging around home or going to a power yoga class; this is the website for all my friends who ask salespeople in stores for the outfit on the mannequin.
Service is the best thing about Activa; they will actually tell you (if you call them, they are not psychic) if a particular piece of clothing of a brand runs large or small so you can order online or by phone with less guesswork.
Sorry guys, Activa only carries women's clothing, but you can still shop here for your sister, girlfriend, mother, or wife for Valentine's Day and save enough to buy her some flowers too!
