When you look at the tag in your clothing, you usually expect to see familiar fabric names, such as cotton or nylon. That's not the case with Lululemon garments. The folks at Lululemon have created and named their own fabric blends. These blends are designed to withstand the rigors of exercise.

Luon is a nylon/spandex blend with a soft, cottony feel. While it's a fairly heavy fabric, it is breathable. You can also find leggings made of "Light Luon" and "Seriously Light Luon."

Luxtreme is a lightweight fabric designed for running. It feels smooth and slick, and it doesn't pill or create a lot of friction.

Nulu is extremely lightweight. It feels softer than Luxtreme, but it is more slippery than it is cottony. Because it's so lightweight, Nulu is not as supportive or durable as Luon or Luxtreme. Rather, it is intended for low-impact activities like yoga.

Lululemon leggings come in sizes ranging from 0/XXXS to 14/XXL. While the company lists a dress size alongside a S-M-L-type size, it's worth noting that Lululemon's sizes tend to run small. You may want to check the size chart for your chosen leggings to see the waist and hip measurements in inches.

You can buy both cropped and full-length Lululemon leggings. Cropped leggings come in a range of lengths, from just below the knee to just above the ankle. All Lululemon cropped leggings list their inseam in inches, which is particularly handy if you're much taller or shorter than the average model.

Lululemon leggings come in a wide range of colors and prints, so you can find a variety of options no matter what your style is. Some prints are highly popular, and because these leggings are manufactured in limited quantities, they may sell out quickly.

Lululemon leggings are categorized by a range of "sensations," from tight to relaxed.

Figure out what you want from your leggings, then choose a pair to suit you.

• Relaxed Lululemon leggings are looser than your average pair of yoga pants, with the fabric sitting away from your skin.

• Naked Lululemon leggings are made from ultra-light Nulu fabric. They are designed to feel like you're wearing nothing, giving you complete freedom of movement.

• Hugged Lululemon leggings could be for you if you you like pants with a lot of support. They offer plenty of lift and support around the waist and posterior, which is helpful for anyone who usually lacks confidence in leggings.

• Tight Lululemon leggings feel highly supportive all over. They're designed to keep the muscles engaged for workouts, but for general wear, they feel too restrive.

• Held-In Lululemon leggings are similar to their “tight” counterparts, but instead of being tight all over, they're supportive around the hips, abs, bottom, and thighs.
