A tech pack is also known as a specification sheet. Tech packs contain detailed information about your garment design like the size measurements, care label instructions, art-work placement, fabric specifications, packing instructions etc. Factories use your tech pack to quote price and make samples. 

I like to think of a tech pack as a contract between fashion designer and garment manufacturer. If you live in New York and are having your garments produced in Ho Chi Minh City, then you will need to communicate your design ideas over a language and culture divide. All the details of your garment need to be communicated, understood, discussed and brought to life by a team of people from a different culture who speaks a different language. Tech packs facilitate this process by putting all the design details on paper in numbers and images to prevent misunderstandings. When problems happen you can easily know who was at fault by referencing the tech packs. You have an idea in your mind. You need to communicate your idea to a Vietnamese merchandiser. The Vietnamese merchandiser cannot read your mind. This is why you absolutely must write down your ideas in technical terms in a tech pack. Otherwise gross misunderstandings are guaranteed which wastes time and money. Next is an example of: What is a garment tech pack or spec sheet?

Why is it necessary to use a garment tech pack or spec sheet?

A good sewing factory will quote price quickly and make a sample quickly. To do this they need the detailed information that is in your tech pack. If the factory has to guess what the details are and they guess wrong then they are losing time and time is money. Factories like to work with fashion brands who know exactly what they want and can communicate it clearly one time so that the factory’s team can get the price quote and sample right the first time. A well done tech pack shows the factory that the designer knows what they want and gives the sewing factory confidence that there will not be any significant changes. Change is the enemy for both sides. Know what a garment tech pack is or spec sheet and use it to communicate all the details of your garment efficiently.
