How We Test: Chaze Fit's Product Testing Methodology

Last Updated: August 2026 | Author: Ankit Mange, Founder, Chaze Fit

Every specific number in a Chaze Fit product description - a GSM weight, a wash count, an hour count for cold retention, a force reading for a seam pull test - comes from a documented test, conducted the way described on this page. This page exists so anyone can see exactly how those numbers were generated, rather than taking them on faith.

Who Does The Testing

Primary Tester

Ankit Mange, founder of Chaze Fit, conducts and personally documents the majority of product testing. He lives and trains in Mumbai, and the bulk of testing happens across three Mumbai gyms with different climate profiles: one fully air-conditioned (22°C), one semi-air-conditioned (26°C), and one non-air-conditioned (28-36°C depending on season). This spread matters because most Indian gym-goers train in the second or third category, not the first, and most product testing published by larger brands is conducted only in the first.

When A Panel Is Used Instead

For products where a single body type cannot represent the range of people who will wear the product, testing uses a structured panel instead of individual testing alone. The sports crop top specification, for example, was set using a 12-woman panel across three Mumbai gyms over 60 days, because opacity-under-stretch and fit behaviour vary meaningfully by body type in a way one person's testing can't fully capture. Panel size and composition are stated in the relevant product guide whenever a panel is used.

What Equipment Is Used

How A Specification Gets Set

The process is the same across every product category:

1. Identify the failure. Testing starts from a specific, observed failure - a vest turning see-through, a bottle going warm, a bag tearing at the eyelet - not from a spec sheet.
2. Test a range, not one option. Multiple GSM weights, materials, or construction methods are tested side by side under identical conditions, never just the option that was eventually chosen.
3. Test in real Indian conditions, not lab-only conditions. Where relevant, testing happens in actual non-AC gyms, on actual Indian travel routes, and during actual monsoon humidity - not exclusively in a controlled lab environment.
4. Record the comparison, not just the winner. Product guides show the data for every option tested, including the ones that failed, so the reasoning behind the final specification is visible.
5. Publish the numbers. Wash counts, hour counts, force readings, and temperature readings are stated as specific figures in the relevant product guide, not summarised as "tested extensively."

What This Testing Is - And What It Isn't

This is important to state plainly: Chaze Fit's testing is in-house, founder- and panel-led testing conducted under real-world Indian conditions. It is not third-party laboratory certification, and none of the figures in Chaze Fit's product guides carry an external certification body's name. Where a claim could be confused with an industry-standard certified rating (for example, UPF ratings on arm sleeves), the relevant product guide states this distinction directly rather than letting the two blur together.

The value of this testing is that it's specific, comparative, and conducted in the actual conditions Indian gym-goers train in - not that it replaces formal certification. For products where a certified rating exists and is used (for example, a stated UPF 50+ figure), that rating's source is the fabric manufacturer's certification, and Chaze Fit's own testing covers how that rating performs in practice - for example, under stretch - which is usually not something the base certification addresses.

Where To See This Applied

Every product guide in the Chaze Fit Journal and category guide (gym vests, sweatpants, water bottles, and every other product line) includes a "What We Tested" and "What We Found" section built using this methodology. If a number appears in a Chaze Fit product description, the test behind it is documented in the corresponding guide.

Frequently Asked Questions

How does Chaze Fit test its products?

Every specification is set through comparative testing against alternative GSM weights, materials, or constructions, conducted in real Indian gym, travel, and climate conditions.

Who conducts Chaze Fit's product testing?

Ankit Mange, founder of Chaze Fit, conducts and documents the primary testing personally, supplemented by structured panels for products needing a wider range of body types.

What equipment does Chaze Fit use for testing?

A digital probe thermometer, pinless moisture meter, force gauge, lux-calibrated fluorescent light rig, standardised abrasive pad, and digital scale.

Are Chaze Fit's testing claims independently verified?

No. All testing is conducted in-house by Chaze Fit and is not third-party certified.
