Setup and First Use
Before wearing your new Calvin Klein Cotton Classics Boxer Briefs for the first time, it is recommended to wash them according to the care instructions provided in the 'Care and Maintenance' section. This initial wash helps to remove any manufacturing residues, ensures optimal comfort, and prepares the fabric for regular use.

Operating (Wearing and Fit)
The Calvin Klein Cotton Classics Boxer Briefs are designed with a signature fit for maximum comfort. They feature a full rise, with the waistband sitting comfortably above the hip, and a longer leg line that extends low on the thigh. This design provides ample coverage and helps prevent the briefs from riding up during activity.

Each pair includes a functional fly and a contoured pouch for supportive comfort. The soft, flexible logo waistband is engineered to stay securely in place without excessive compression, retaining its shape even after repeated wear and washes. For the best fit, consult the size guide below and choose the appropriate size based on your waist measurement.

Care and Maintenance
Proper care is essential to maintain the quality, fit, and longevity of your Calvin Klein Cotton Classics Boxer Briefs. Please follow these guidelines:
- Washing: Machine wash cold with similar colors. Using cold water helps preserve fabric integrity and color.
- Drying: Tumble dry on low heat. For optimal results and to extend the life of the garment, hang drying is highly recommended. Avoid high heat, which can damage the elastic and fabric.
- Bleaching: Do not use bleach or any harsh detergents, as these can degrade the cotton fibers and affect color.
- Ironing: Do not iron. The cotton fabric is designed to be low-maintenance and ironing is not necessary.
- Dry Cleaning: Do not dry clean.

Troubleshooting Common Issues
- Shrinkage: As these boxer briefs are made from 100% cotton, slight shrinkage may occur after the first wash. To minimize this, always wash in cold water and consider hang drying instead of tumble drying. If you are between sizes or at the upper limit of a size, choosing the next size up may provide a more consistent fit after washing.
- Elastic Band Loosening: The flexible waistband is designed for durability and to retain its shape. If the elastic band appears to lose its stretch prematurely, ensure that the care instructions, particularly avoiding high heat during drying, are strictly followed. Excessive heat can degrade elastic fibers over time.
- Color Fading or Staining: To prevent colors from fading or potentially staining other garments, especially during initial washes, it is advisable to wash dark-colored briefs separately from lighter items.
