Launching an activewear line without a complete tech pack is one of the fastest ways to burn through your production budget. Fit issues, fabric mismatches, and construction errors discovered after cutting can delay launches by weeks and destroy margins. This is why brands searching for a reliable activewear tech pack checklist manufacturer need a partner who understands both design intent and factory-floor reality.
At CI Aliada SAS, a full package apparel manufacturer based in Bogota, Colombia, we review hundreds of tech packs every year. The brands that succeed are the ones who arrive with detailed, production-ready documentation. This article breaks down exactly what belongs in an activewear tech pack, so your next production run starts smooth and finishes on spec.
Activewear is technically demanding. Four-way stretch fabrics, compression zones, moisture-wicking finishes, and flatlock seams all require precision that basic apparel doesn't. A generic tech pack template used for t-shirts or dresses will not capture the details a leggings or sports bra factory needs to build your garment correctly the first time.
Any experienced activewear tech pack checklist manufacturer will tell you that missing information forces the factory to make assumptions. Those assumptions rarely match your brand vision, and by the time samples arrive, you've lost a full development cycle. A complete tech pack eliminates guesswork and keeps communication clear between your design team and the production line.
Include flat CAD sketches showing every seam line, panel, and construction detail. For activewear specifically, mark:
This is one of the most frequently overlooked sections, yet it directly impacts fit, compression, and durability. Your tech pack should specify:
Without a defined fabric weight, a manufacturer may substitute a similar-looking fabric that behaves completely differently on the body. This is a common cause of returns in the activewear category.
Seams affect comfort, chafing resistance, and garment lifespan more than any other construction element in activewear. Your checklist should specify seam type for every panel:
Indicate stitch density (stitches per inch) and thread type — polyester thread with stretch recovery is standard for activewear to prevent seam popping during high-intensity movement.
Gussets are essential for range of motion in leggings, shorts, and bike shorts, yet they're one of the most poorly documented elements in amateur tech packs. Your gusset section should include:
A properly specified gusset prevents crotch blowouts, one of the top quality complaints in activewear manufacturing. Any competent activewear tech pack checklist manufacturer will flag missing gusset details before cutting begins, but it's far more efficient when this is defined upfront.
Provide a point-of-measure (POM) chart with tolerances (usually ±0.5 cm to ±1 cm for activewear) covering:
List all trims with supplier references or attach swatches: elastic type and width, drawcords, zippers (preferably #3 or #5 for lightweight activewear), woven or heat-transfer labels, and care labels compliant with your target export markets.
Include your grading increments between sizes so the factory's pattern team can build an accurate size run without back-and-forth clarification emails.
