Key Takeaways
- Proprietary fabric names (Nulu, DreamKnit, Airlift, Dri-FIT) obscure real differences in compression, weight and design intent between brands.
- Vuori's DreamKnit prioritizes everyday softness over studio-specific compression, a genuinely different design goal from Lululemon's Luon or Alo's Airlift.
- Nike's Dri-FIT is a moisture-wicking treatment applied across varied base fabrics, not a single consistent material, which is why it can feel different across products.
Every major activewear brand has given its signature fabric a proprietary name — Nulu, DreamKnit, Airlift, Dri-FIT — which makes direct comparison harder than it should be. Stripped of the branding, the underlying differences come down to a handful of measurable properties.
Lululemon's Nulu and Luon
Nulu is Lululemon's buttery-soft, lighter-weight fabric, generally used in lower-impact pieces where next-to-skin feel matters more than heavy compression. Luon is the older, slightly more structured compression fabric used in original core styles — noticeably firmer and more supportive than Nulu, at a small cost to softness.
Vuori's DreamKnit
DreamKnit is built around a brushed, performance-fleece feel rather than a compression fabric — softer and less structured than either Lululemon fabric, prioritizing everyday comfort over studio-specific support. It's a meaningfully different design goal, not simply a softer competitor to the same goal.
Alo's Airlift and Aloform
Airlift is a compressive, second-skin fabric built for a close, sculpted fit — closer in intent to Lululemon's Luon than to Vuori's DreamKnit, but generally cut tighter. Aloform, used in newer pieces, is a slightly heavier, more structured variant aimed at higher-impact use.
Nike's Dri-FIT
Dri-FIT is less a single fabric than a moisture-wicking treatment applied across a wide range of base fabrics, which is why Dri-FIT products can feel meaningfully different from each other depending on the specific garment. It's the most performance-lab-oriented of the four, generally prioritizing sweat management over the soft-hand feel the others compete on.
Approximate weight range across these four signature fabrics
140–260 gsm
Lululemon's Nulu and Vuori's DreamKnit sit toward the lighter end; Luon and Aloform toward the heavier, more structured end.
The practical takeaway: a fabric's proprietary name tells you almost nothing on its own. What matters is whether it's built for compression versus everyday softness, and how it holds up specifically to your own wash-and-wear routine — information that shows up more reliably in a brand's own care instructions and weight specs than in the marketing name itself.
Frequently Asked
Which of these signature fabrics is best for high-impact workouts?
Lululemon's Luon and Alo's Aloform are built with more structure and compression, generally suiting higher-impact use better than the softer, less structured Nulu or DreamKnit.
Does a proprietary fabric name guarantee consistent quality across a brand's products?
Not necessarily — Nike's Dri-FIT, for example, is a treatment applied to varying base fabrics rather than one consistent material, so the actual feel and performance can differ meaningfully between products carrying the same fabric name.
