Black Diamond® Size Chart

Fit guidance for apparel, gloves, harnesses, helmets, packs, climbing shoes, and approach shoes.

Use this Black Diamond® Size Chart to compare common fit ranges before choosing your size. Measurements are shown in inches and centimeters where available. For apparel and body-fit gear, sizing refers to body measurements, not garment dimensions.

Product fit can vary by style, intended use, layering, and personal preference. Always review the product detail page before ordering, especially for technical gear such as harnesses, helmets, packs, climbing shoes, and gloves.

Gloves & Mittens

For glove and mitten sizing, measure from the crease at the base of your wrist on the palm side to the tip of your middle finger.

Footwear Size Charts

Footwear fit depends on the activity. Climbing shoes are usually worn snug-to-tight for connection and precision, while approach shoes are typically chosen closer to everyday footwear fit.

How to Choose Your Size

Start With the Product Type

Choose the table that matches the product you are buying. Black Diamond® apparel, gloves, harnesses, helmets, packs, and footwear use different measurement points.

Match the Important Measurement

For technical gear, the most important measurement is the one that affects safe fit and comfort: waist and leg for harnesses, head circumference for helmets, torso and waist for packs, and hand length for gloves.

Think About Layering

If you plan to wear base layers, liners, heavy socks, or insulated layers, allow room for that extra bulk. A closer fit may feel cleaner, while extra room may feel better for cold-weather layering.

Check the Product Page

Some Black Diamond® products include style-specific fit notes, size ranges, or product measurements. Use this page as a guide, then confirm the details on the item you are considering.

Measuring Tips

  • Use a soft measuring tape and keep it level without pulling it too tight.
  • Chest: measure around the chest or bust just under the arms and across the shoulder blades.
  • Arm length: measure from the center back of the neck, across the shoulder, and down the arm to the wrist.
  • Waist: measure around the narrowest part of the waist.
  • Hip: measure around the widest point of the hips.
  • Helmet: measure around the largest part of the head, about one inch above the eyebrows.
  • Pack torso length: measure between the top of the hip bones and the C7 vertebra at the base of the neck.

Fit Notes

Slim fit is designed to sit closer to the body. Regular fit offers a classic fit with comfortable ease. Relaxed fit is more generous through the body and can allow more room for layering.

For adult Momentum climbing shoes, fit is based on the shape and dimensions of the last rather than a roomy street-shoe fit. A snug-to-tight climbing shoe fit can improve connection with the rock, while a less aggressive fit may feel better for longer sessions.

Between Sizes

If you are between sizes in apparel or gloves, size down for a closer fit or size up for extra room and layering. If you are between sizes in a harness, helmet, or pack, make sure the key measurement stays comfortably inside the listed range after adjustment.

For footwear, consider how you use the shoe. Choose a more precise fit for climbing performance and a more comfortable fit for longer approaches or all-day wear.
