Question 1

Are Fastarry scrunch leggings squat-proof?

Accepted Answer

Yes. Fastarry scrunch leggings use 230gsm+ double-knit seamless fabric that passes the full-stretch opacity test. They stay completely opaque during deep squats, deadlifts, and hip thrusts.

Question 2

What's the difference between seamless and regular leggings?

Accepted Answer

Seamless leggings are knitted as one continuous piece without stitched seams. This eliminates chafing, provides better stretch recovery, and increases durability under tension. Regular leggings use cut-and-sew construction with visible seams that can dig in during deep movements.

Question 3

Do butt-lifting leggings actually work?

Accepted Answer

Yes, through optical contouring rather than compression. Fastarry's V-back scrunch seam follows the natural glute line, creating shadow and shape that enhances your curves without restricting blood flow. The effect is immediate and comfortable for all-day wear.

Question 4

What size should I order if I'm between sizes?

Accepted Answer

For a compression fit ideal for heavy lifting, size down. For a comfort fit best for yoga and casual wear, size up. Fastarry's seamless knit fabric has more give than traditional cut-and-sew leggings, so both options will fit well.

Question 5

How should I wash Fastarry leggings?

Accepted Answer

Machine wash cold, inside out, with no fabric softener. Fabric softener breaks down spandex fibers and reduces elasticity over time. Air dry or tumble dry on low heat. This extends the lifespan of your leggings by 2-3x compared to hot washing.

Question 6

Are Fastarry leggings see-through?

Accepted Answer

No. All Fastarry leggings use double-layer knit construction at 230gsm+ fabric weight, ensuring full opacity even at maximum stretch. Every style passes our squat-proof opacity test before production.

Question 7

What fabric are Fastarry leggings made of?

Accepted Answer

Fastarry leggings are made from a premium blend of 75% Nylon and 25% Spandex. This combination provides a buttery-soft feel, 4-way stretch with full recovery, moisture-wicking properties, and quick-dry performance.

Question 8

Can I wear scrunch leggings for yoga?

Accepted Answer

Absolutely. The seamless construction and 4-way stretch make Fastarry scrunch leggings ideal for yoga, including hot yoga. The high-rise waistband stays in place during forward folds and inversions without digging in.

Question 9

Do Fastarry leggings roll down at the waist?

Accepted Answer

No. Fastarry leggings feature a wide, high-rise waistband with integrated silicone grip that stays in place during squats, deadlifts, and high-intensity movements. The seamless waistband also eliminates muffin-top compression.

Question 10

Does Fastarry ship internationally?

Accepted Answer

Yes. Fastarry ships worldwide with support for multiple currencies including USD, GBP, EUR, CAD, and AUD. Standard and express shipping options are available depending on your location.
