Check the seat at the bottom of the squat. That is where leggings tell the truth.
Squat proof leggings can make the difference between focusing on your next set and glancing at the mirror after every rep. I have grouped 11 options Canadian shoppers can compare by workout, feel and budget. Opacity depends on fabric, colour, size and how the pair sits on your body, and no fabric name guarantees coverage.
Prices below are rough Canadian list-price ranges. They shift with colour, season and sales, so look at the current product page first, especially for sale colours and final-sale items.
Does this pair actually pass the test?
Put the leggings on in bright, even light, turn away from the mirror and do a slow bodyweight squat. Look at the seat and upper thighs at the bottom. Then try a forward fold and a lunge, because those positions can show sheer spots that never appear when you are standing still.
Wear the underwear you would normally pick for a workout. A contrasting colour makes coverage easier to judge, though seams and underwear lines are a separate issue from fabric opacity. If the material pulls very taut over your hips, try the next size up before writing the leggings off as see-through. Stretched fabric looks lighter, feels worse and wears out faster.
For the most reliable check, take a quick phone photo from behind in daylight. I know, not glamorous. The first time I did it, I found a thin patch my bathroom mirror had hidden for weeks. Then move around for a minute: squat, step up, walk. A good pair stays put without constant tugging.
Sizing, and why tighter is not better
Start with the brand’s size chart and your hip measurement. Between sizes? Think about the fabric and the workout. A firm compression legging may feel better in the larger size, while a softer yoga style fits differently. Don’t size down to chase a tighter look, since that stretches the knit thin and makes an opaque fabric look sheer.
With a smaller waist and fuller hips, look for a contoured waistband or a cut with more room through the seat. For a straighter shape, a high-rise waistband with a drawcord helps keep things secure. Taller shoppers should check inseam options, and petite shoppers can look for cropped lengths that will not bunch at the ankle.
Shopping online? Check the return policy before you pull off the tags. Try the pair at home with a squat, a lunge and a short walk.
Overall picks
These four cover different styles, from controlled strength sessions to yoga and studio classes. Softer fabrics usually feel best for low-impact movement rather than heavy lifting.
Lululemon Wunder Train High-Rise Tight — about CAD $98–$128. This is the firmer option for lifting and interval days, with a close fit made to stay in place. It may feel too compressive if you like a barely-there legging, so try your usual size and, if you can, a neighbouring one.
Lululemon Align High-Rise Pant — about CAD $98–$128. Align suits yoga, walking and days when softness matters more than compression. It is lovely for stretching. I would not pick it first for barbell work or repeated high-friction training, where a more durable knit may serve you better.
Aritzia TNA Butter Atmosphere Hi-Rise Legging — about CAD $68–$88. The smooth, soft feel makes this a tempting studio-to-errands pair, and the high-rise cut gives plenty of waistband coverage. It can run warm in a hard workout, so save it for yoga, Pilates or a moderate gym day.
Alo Airlift High-Waist Legging — about CAD $128–$148. This sleek, more compressive style works when you want a held-in feel and a smooth finish. The price is a real commitment and the glossy hand-feel is not for everyone. Check the fit in motion before making it your all-purpose pair.
Budget pairs that deserve a look
A lower price does not automatically mean poor coverage. Fabric weight and fit just need extra attention. If you want a dependable workout pair without paying premium-label money, compare these.
Old Navy PowerSoft High-Waisted Leggings — about CAD $45–$70. PowerSoft is a practical everyday choice for walking, gym machines and lighter strength sessions. Fabric feel can vary a little between versions, so read the care label and squat-test your colour, particularly if it is pale or bright.
Gymshark Adapt or Vital Seamless Leggings — about CAD $60–$80. These often appeal to shoppers after a snug fit and sculpted look. Seamless knit can feel supportive, but textured panels may stretch differently across the body. Check the seat and inner thigh instead of assuming darker sections are opaque.
CRZ Yoga Butterluxe Leggings — about CAD $35–$55. The soft, flexible feel is a strong draw for yoga and low-impact sessions, and it undercuts premium studio leggings. Some versions are quite lightweight, though. Test coverage in your chosen colour before wearing them for deep squats under bright gym lights.
Decathlon high-waisted fitness leggings — about CAD $35–$60. Decathlon’s workout basics suit simple, no-fuss training. Check the exact model, since support and fabric weight vary across the range. The trade-off may be fewer fashion details or colours than you would find higher up.
Fabric names are clues, not promises
Nulu, Butter and compression knit tell you something. Nulu-style fabrics tend to feel soft and light, which works nicely for yoga, and Butter-soft knits lean into that brushed, cozy feel. Compression fabrics feel firmer and can suit lifting or high-impact classes, though a tight waistband is not automatically better support.
Comparing lululemon Align and Aritzia TNA? Start with the activity, not the label. Align is known for a light, soft feel, and TNA Butter styles are also positioned as soft studio leggings, with details varying by model. Neither should be judged by fabric name alone. Read the garment composition, check reviews for your intended use and test the exact colour and size you plan to keep.
For bum lifting leggings, look at seam placement, waistband shape and how well the fabric recovers. A back seam or contour detail can create a lifted look, but it will not replace a good fit. If the waistband rolls down when you bend, or the fabric strains across the seat, try another cut or size. Honestly, a comfortable pair that stays in place beats a dramatic seam you adjust all afternoon.
My view: keep the pair that survives the movement test and still feels good by the end of class, whatever the product description promises.

Frequently Asked Questions
How do I know if leggings are squat proof?
Try them on in bright light, face away from a mirror and do a slow squat, a forward fold and a lunge. Check the seat and upper thighs. A quick phone photo from behind helps too.
Can a larger size make leggings less see-through?
Often, yes. Fabric stretched tight across the hips or thighs looks lighter and thinner. The next size up can restore coverage and feel more comfortable.
Are budget leggings ever squat proof?
They can be. Price alone does not decide coverage, but fabric weight and fit matter, so test the exact colour and size you plan to keep.
Is lululemon Align good for heavy lifting?
It is better suited to yoga, walking and stretching. For barbell work or lots of friction, a firmer and more durable knit may suit you better.
