Lululemon’s classic high-rise legging style introduced before Align is Wunder Under.
Wunder Under was one of lululemon’s foundational legging franchises and became especially associated with yoga and everyday wear. Earlier versions were commonly made from Luon, the brand’s cottony-soft performance fabric, while other versions used smoother technical materials such as Luxtreme. The style was offered in multiple rises, lengths, colors, and fabric variations over the years.
Align arrived later, launching in 2015 with Nulu fabric and a stronger emphasis on weightless, barely-there comfort. That timing is why Wunder Under is the relevant predecessor in this question. The names can still be confusing because Wunder Train developed within the broader Wunder family but is positioned for more intense training and faster drying.
Instill is a newer, more supportive style, and Fast and Free is designed around running features such as lightweight construction and pockets. Although lululemon has changed and periodically retired parts of the Wunder Under range, the name remains one of the brand’s best-known early legging labels.
