The Define is a lightweight jacket that is perfect for a variety of situations: Commute to and fro the gym, outdoor activity, travel, or everyday athleisure. (Spoiler: This is my favorite version of the Define.) The Define jacket is also offered in a hooded version, made of Nulu. The Define jacket is also released seasonally in other fabrics, like Nulu (in the summer) or Rulu (in the winter). It’s stretchy, breathable, and retains its shape well. Luon is a technical fabric made of nylon and Lycra. The Define is made out of Lululemon’s Luon fabric, which feels sort more cottony than slick. The Define jacket is a fitted jacket with flattering seams, a slightly flared shape, long sleeves with thumbholes, and zippered pockets. But first let’s take a quick look at the Lululemon Define. In this post, I’ll be comparing several top-rated activewear jackets (all available on Amazon). If you’re looking for the BBL effect in an affordable jacket, you’ve come to the right place! But not all of us can afford the hefty price of the actual Lululemon Define jacket.


Though it’s a longstanding Lulu classic, the Define jacket recently experienced a spike in popularity due to viral Tik Tok videos highlighting the “BBL effect” of this piece. Its classic and functional design has inspired other brands to make a similarly styled product. The Define jacket is one of Lululemon’s most popular items.
