How to Measure

Bust / Chest

Measure around the fullest part of your bust or chest, keeping the measuring tape level and comfortably snug.

Waist

Measure around your natural waistline without pulling the tape too tightly.

Hip

Measure around the fullest part of your hips while standing naturally with your feet together.

For the most accurate results, use a flexible measuring tape and compare your measurements with the relevant size chart.

Choosing Your Jacket Size

When selecting a down jacket, consider your preferred fit and whether you plan to wear additional layers underneath.

For a closer fit: Choose the size that best matches your body measurements and the product's fit description.
For a relaxed fit: Consider sizing up if you prefer extra room.
For layering: Allow enough room for sweaters or other winter clothing underneath.

If you are between two sizes, check the product-specific size chart and fit description before deciding. Choosing a larger size may provide additional room, but the best choice depends on the jacket's design and cut.

Important Size Information

The measurements in these charts are general body measurement references, not the actual measurements of the jackets.

FEI YI outerwear may feature regular, relaxed, oversized, or slim fits depending on the style. Actual sizing and fit may vary by product.

US numeric size conversions are approximate and are not guaranteed to match every brand's sizing standards. Please refer to the measurements and size recommendations on the individual product page when available.
