Tech Pack Creation for Gymwear

I'm looking for a detailed tech pack for a new line of gymwear. The tech pack should include:

- Leggings - invisible style scrunch, nothing tacky or blatantly obvious. Pockets version and no pocket version.
- Sports Bras - flattering styles that show off the abdomen and chest, think the crossover bra designs, halter neck, designs that hug and lift
- T-shirts - oversized unisex streetwear style but a nice softer texture
- Hoodies - oversized and fleecey unisex

Ideal Skills and Experience:
- Experience in creating technical packs for apparel
- Knowledge of gymwear design and construction
- Proficiency in specification sheets, flat sketches, and material details
- Strong attention to detail and accuracy

Please provide samples of previous tech packs created.
