How to Create a Hoodie Tech Pack with AI
Step-by-step guide to creating a complete hoodie tech pack with AI — from fabric specs to hood construction, kangaroo pocket details, and graded sizing.
Why hoodies need detailed tech packs
Hoodies are one of the most common garments in streetwear, athleisure, and casual wear — but their construction complexity is often underestimated. Hood shape, kangaroo pocket dimensions, drawcord routing, ribbing tension, and shoulder construction all require precise specification to avoid costly sample revisions.
A complete hoodie tech pack covers hood panel construction, pocket bag dimensions, cuff and hem rib specs, drawcord type and length, and eyelet placement — details that generic templates often miss.
Step 1: Define your hoodie type
Start by specifying the hoodie subcategory. A pullover hoodie has different construction requirements than a zip-up. An oversized streetwear hoodie needs different measurements than a fitted athletic hoodie.
- Pullover vs full-zip vs half-zip
- Fit: oversized, boxy, relaxed, regular, slim
- Hood style: single-layer, double-layer, lined, crossover
- Pocket: kangaroo, split kangaroo, side-seam, none
- Weight class: lightweight (180-220 gsm), midweight (240-280 gsm), heavyweight (300-400 gsm)
Step 2: Generate the tech pack with AI
Describe your hoodie with all construction details and generate the tech pack. The AI produces category-appropriate specifications — a heavyweight cotton hoodie automatically gets different seam allowances and stitch types than a lightweight performance hoodie.
Review the generated BOM for correct fabric weight, thread type, drawcord material, eyelet finish, and rib composition. Check measurements against your fit intent — oversized hoodies need wider body measurements and longer sleeves than standard sizing.
Step 3: Verify hood construction details
The hood is the most complex part of a hoodie tech pack. Verify panel count (2-panel vs 3-panel), seam placement, topstitch details, and drawcord channel construction.
Check that the hood opening measurement matches the neckline circumference with appropriate ease. A common tech pack error is hood opening that is too tight or too loose for the neckline.
Step 4: Check pocket and trim specifications
For kangaroo pockets, verify pocket bag depth, entry angle, bartack placement, and whether the pocket is single-layer or lined. For zip hoodies, verify zipper type (YKK 5VS is standard for heavyweight), slider style, and tape color.
Ribbing specs should include rib knit type (1x1, 2x1, 2x2), composition, weight, and finished width for cuffs and hem.
Step 5: Export and review
Export the tech pack as PDF and review the flat sketches against your construction specs. Verify that hood shape, pocket placement, and seam lines match your intent. Use the AI chat to make any final adjustments before sending to your manufacturer.
