an in-depth guide

Take a read below:

Generation of garment (I, II, III, IV)
Uno, dos, tres, cuatro. No matter how you say it, these little Roman numerals are how we indicate a new version of a much loved item. Every season, we count on your feedback to figure out exactly what you love and what can be improved. Our quest never ends when it comes to fit and function and I, II, & III mark the way.

*[Fabric name]
Whenever you see the (*) followed by a fabric, it indicates that this fabric has been used to create the product. It can represent the main fabric used, or a secondary fabric used only in sections. *Tweed, *Mesh, *Rib and *Org are all examples.

Brushed (*Br or *Brushed)
Brushed promises a warm, soft layer against your skin. Specifically, the fabric's bottom layer has been agitated and brushed to create a cozy, super-soft feel.

Durable Water Repellent (DWR)
Fabric has been treated with a finish that causes water to bead off of the surface to keep you dry!

Water repellant vs waterproof: Our Waterproof products have an outer shell capable of repelling water AND taped seams to keep all water from penetrating. Water repellant garments do not have taped seams.

Organic (*Org or *Organic)
Certified Organic Cotton is an exciting addition to our amazing fabric line. Read all about this breathable natural option in Elissa's "(fall)ing into organic cotton" blog.

Pique (*Pique - pronounced "pee-KAY")
Our pique luon fabric is luon that has been woven to give a more textured look and feel. It’s like wearing your favourite knit sweater or pants with the superb 4-way stretch and sweat wicking abilities you know and love.

Ruffle (*Ruffle)
A textured detail to add originality to your athletic gear!

Sparkle *Sparkle
Subtle silver-coloured threads woven into the fabric make you shine on the outside, too.

Special Edition *Special Edition
A new detail, feature, or pattern puts a twist on a core item.

Reversible (*RVRS)
Your outfit possibilities double, thanks to our reversible options in both pants and jackets. Our flat-seam technology enables us to offer two unique looks in one.

SL, SS, LS
We love to provide our guests with all the options. You can choose between sleeveless (SL), short sleeve (SS), or long sleeve (LS) to ensure the right product for every workout.

Regular (*R)
This indicates our standard inseam. For ladies, the inseam is 31.5" (size 2/4 = 31"). Men can expect 33". Take a look at our size chart for more info.

Tall (*T)
Those with wonderfully long legs need not worry – a tall length is made just for you! Women's *T inseam is 35"  for sizes 4 & 6 and 35.5" for 8-12. Men's *T is 36".

And there you have it. Now take your new-found knowledge and shop fearlessly!

To measure your inseam you'll need a friend and a measuring tape. (Easy enough, right?)

Wearing pants that are fairly fitted or shorts, and standing up straight, take the end of the measuring tape (the 1" end) and hold it at the top of your inner thigh.

(Make sure you're standing up straight! If you bend over a little you may end up with shorter pants than you want!)

Get your friend to pull the tape straight down the inside of your leg to the floor – the number that's hitting the floor is your inseam measurement! Make sure you're looking at the inches side of the tape.

**Tip - If you are planning on wearing shoes that have thick soles – like Shox - you may want to add 1" to your inseam length to ensure your pants aren't too short**

Want to find out the length of pants you'll need based on your newly discovered inseam? Check out our size chart here: http://www.lululemon.com/education/info/sizes If you're an inbetween length, don't forget we offer free hemming at all of our stores!
