Tech Pack Review - Outdoor Clothing Garments

Im currently developing an outdoor clothing brand. Im at the stage where ive trademarked my brand, developed some initial garment designs and am now producing Tech Packs to be sent to prospective clothing manufacturers. Im new to the industry so I need a clothing designer ideally with relevant experience working with outdoor clothing to review the tech packs ive produced with particular emphasis on;
- Sizing - Are the measurments enough to construct the garment and if not some advice on suitable measurments required for my desired fit. Also is the sizing structure to industry standard?
- Materials- Are the materials blend ideal for purpose ( can be discussed further)
- General terminology - Does the document read as would be expected from a manufacturers perspective?
- General Comments - Would you expect to be able to produce the garment with the pack on information - if not, whats missing?
- Labelling - Is the label information compliant with UK legislation
- Any general advice in terms of clothing manufacturers both domestically / internationally. Sourcing platforms are saturated with clothing manufacturers and it would be good to get a steer in cutting the wheat from the chaff.

A detailed review in the style of a marked up PDF of Techpacks produced with comments + a document highligting general comments / advice.

Thanks
