UNDERSTAND IT VISUALLY
Fit it over the intended layers.
Review the garment over a shirt, knit or midlayer as intended. Pattern ease and insulation compression affect the fit discussion.
Record the fitting layers and review movement.
Define the layer beneath the jacket
State whether the garment is designed over a shirt, knitwear or a midlayer. Ask users to try the jacket with the intended layers so sleeve, shoulder, chest and hem ease can be judged realistically.
Fit changes the insulation system
Fit influences compression, air space, mobility and how the garment closes around openings. These effects interact with fill distribution, baffles, shell and weather.
Turn fit into review points
Use a fit model or representative wearer, approved size chart, movement checks and clear comments. Record which sample size and layers were used. Do not infer a universal temperature rating from a fit description.
Questions buyers ask
Is a looser jacket always warmer?
No. Fit, layering, openings, fill and use all interact. Evaluate the intended fit and clothing system.
Which motions should be checked?
Use motions relevant to the product, such as reaching, sitting, lifting arms and layering over the planned midlayer.
