The Heavy-duty belt is 11cm (4.25" ) wide, compared to the slightly narrower Kinesis standard-weight Black Belt which is 9cm (3.5") wide, providing more support for the heavier loads.

• Twice as thick as the standard-weight Kinesis Black Belts (20mm foam compared to 6mm).
• Commonly used with the Heavy-duty Pack Frame
• Heavy-duty belts are made from bi-laminate foam for a more comfort with heavy loads (closed cell or stiffer foam on the outside and softer open-cell foam on the inside).
• Conically cut (curved like a banana), providing a good fit for both women and men.
• Inside surface of our belt utilizes SuperKnit, a soft breathable foam-backed knit fabric. The outer surface is made of 500-denier DuPont Cordura® Plus nylon fabric.
• Kinesis belts fit over streetwear, including your pants belt.
• All belts include a pair of B501 50mm (2") sliders which helps keep the belt buckle from loosening.
• Belts are cut with extra webbing for use over winter apparel.

Sizing
Order the same size as your pants waistband. Kinesis belts are sized to fit over normal streetware, including a regular pants belt.
Our description, for a large belt, says "Optimum fit for 34-38 waist, (fits up to 50")," which means that the padded portion of the belt will wrap around the majority of your waist if you are in the 34 to 38-inch range. Since we provide an extra webbing "tail" the belt will fit a larger waists -- the padding just won't surround your waist. Also, this long tail enables the belts to be used effectively over winter apparel.

Always get the largest belt you can fit into, as it will provide you with more attachment points, however if you are borderline between two sizes, get the smaller size as the belts can go larger, but they cannot cinch Down much past the recommended size.

For women — keep in mind the measurements are for your natural waist or narrow point above your hips. This is much higher than where most women wear their pants these days. If you plan to wear your Kinesis belt lower on your waist or hips, measure that area accordingly. (It may mean going up a size.)

Special Note for those traveling to the Arctic: Quality buckles are made from either Nylon or acetal (Delrin®). We use a Nylon/Acetal combination for our belts because at normal temperatures it is stronger & more impact resistant than 100% acetal. Nylon, however, may not be suitable for high humidity (white water rafting, kayaking or canoeing) or extreme subzero (-20ºF or less) temperatures. Special order belts with substitute acetal buckles are available at no additional cost.
