The layer that reduces returns.

Fit and sizing

The question of fit

In activewear the purchase decision is one thing: will it fit, and will it hold? This is the layer that reduces returns and the one the current site does not have in any usable form — and you are already paying for a returns platform.

  • Model reference: “the model is 1.7X m and wears size M” [CONFIRM the height and size of each model, per photograph]
  • Between two sizes: the recommendation changes per line — a Compress and a Soft do not behave the same. [CONFIRM the recommendation for each line]
  • See-through. It is the most-asked question about light-coloured leggings, and answering it honestly is a trust asset, not a risk. Each line needs its own opacity note. [CONFIRM line by line]
  • Rise, per style [CONFIRM]
No measurement has been invented. The table below has the right structure — bust, waist, hip and inseam in centimetres — and it is empty on purpose. Sizing information is a required CDC disclosure as well as a UX feature: the customer has to be able to know what they are buying. [CONFIRM the real measurements]

The lines

Five fabrics, five promises

This is the brand’s most defensible asset and today it sits at the third level of a mega-menu, behind four simultaneous discount tiers. Here it is the primary shopping interface. A brand that engineered five fabrics and can explain the difference is not competing on price with anyone.

No technical specification has been invented. Compression, opacity, stretch, breathability and weight are exactly the rows this table needs — and every cell is open, because a compression figure invented to fill a grid is a performance claim.

Shipping and returns

Said plainly, above the footer

This is a conversion section, not a legal one. Clarity here reduces cart abandonment directly.

Free shipping over R$ 600,00

This threshold is yours and it is a genuine, non-eroding incentive. One thing is missing: is it calculated before or after discounts? [CONFIRM]

Right of regret — 7 days (CDC art. 49)

A purchase made away from the premises gives the customer seven calendar days from receipt to cancel, for any reason, with a full refund of everything paid — outbound shipping included. It is not a courtesy, it is law, and it has to be stated in plain language on the product page and at checkout, not only inside a policy page.

Legal warranty — 30 and 90 days (CDC art. 26)

Thirty days for non-durable goods and ninety for durable ones, against defects. It is separate from the goodwill exchange policy, and the goodwill policy must not be presented as if it were the legal minimum.

Size exchanges

The window, the tags-and-unworn condition, and who pays return postage in each scenario (defect, regret, size exchange) [CONFIRM]. The flow runs on Troque Commerce [CONFIRM how it works in practice].

Delivery times

By region, carrier, tracking and what happens on a failed delivery [CONFIRM].

Gift wrapping — R$ 8,00

FAQ

What people ask before buying

Which line should I choose?

It depends what you are going to do. Compress to train with everything held in place, Soft to stretch as if you were wearing nothing, Dry to sweat, Fresh+ to give everything in any activity, and Pump to lift the body and the look. All five lines are theirs, and the comparison table above exists precisely for this.

How do the sizes run?

Size run, measurements in centimetres and a between-sizes recommendation [CONFIRM]. The measurement table is built and empty on purpose — no measurement has been invented.

Are the light colours see-through?

That is the most-asked question about light-coloured leggings, and the honest answer is worth more than the flattering one. Opacity changes by line and by colour. [CONFIRM line by line] — nothing has been asserted here.

How long does delivery take?

Times by region, carrier and tracking [CONFIRM]. What is certain is free shipping over R$ 600,00, which they publish — what is missing is whether that is calculated before or after discounts.

Can I exchange for another size?

Yes, with a window, a garment-condition requirement and a return-postage rule [CONFIRM]. And, separately from that, there is the 7-day right of regret (CDC art. 49), which applies for any reason and refunds the outbound shipping too.

Do you ship outside Brazil?

The site’s country selector lists about forty countries. If those orders are actually fulfilled, the site has to state international delivery times, who pays import duty and whether returns from abroad are possible. [CONFIRM]

Do you accept Pix?

The payment methods published in their footer today are American Express, Diners Club, Discover, Elo, Hypercard, JCB, Mastercard and Visa. Pix does not appear. In Brazil, in 2026, that is unusual enough to be worth asking directly. [CONFIRM whether Pix is accepted at checkout and simply not shown in the icons]

How does The 4am Zone work?

The programme exists and has its own page. What it includes, what it costs and how to join [CONFIRM]. If it is paid or recurring, its billing terms and the right of regret have to be there.

Can I try things on in the stores?

There is a store in Florianópolis and one in Porto Alegre. Addresses and hours [CONFIRM]; both store WhatsApp numbers are correctly formed and do connect.

Which size am I?
