The Heavy-duty belt are 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.

• It is twice as thick as the standard-weight Black (20mm foam compared to 6mm).

• It is 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).



Belt Choices (Regular or Heavy-duty?)
90% of our customers purchase the the standard “black” belt for everyday use (B107, B108 etc. series). Most photojournalists carry their DSLR around their neck, while nature/traveling shooters like the option of a C-Series holster case to shove it away and protect it from the elements. If you carrying a full-size heavy body (i.e. Nikon D3-series or Canon EOS1d-series) plus fast and bulky 2.8 lenses (70-200/2.8) on your waist, then consider the heavier belt--it will provide more support. If you doing a multi-hour walking or hiking, the heavier belt will also be more comfortable and because of the extra padding it tends to stay up better or stick to your waist without suspenders. Of course the trade off is if you are in a hot and/or humid climate, then the heavier belt may prove to be uncomfortable (although the fabric is breathable, the thick bulky foam insulates). Please note that with a fully-loaded belt, the regular-weight “Black Belt” seems a little floppy when removed, but when worn on the waist it provides good support for most average loads, esp. when you consider that the pouches are padded too.



Backpack Use
I personally prefer the “standard-weight” Black Belt for use with the Journeyman pack (up to about 25 lbs. / 11 kg) because much of the weight is distributed throughout the pack frame and shoulder harnesses. Whenever possible, I adhere to the “less is more” philosophy with gear. Be sure you order the B503 adapter with your Journeyman pack if you using a Black Belt.
On the other hand, if you think you might purchase a Heavy-duty Pack Frame then purchase the Heavy-duty belt (B307, B308 etc. series) instead of the “standard” Black Belt. The heavy-duty model has special pockets for the aluminum staves of the P017 or P019 Heavy-duty Frames. The extra rigidty of the heavy-duty belt is needed for heavier loads typically carried on the pack frame.



Buckle in back or buckle in front? (see photo above)
The durable 50mm (two-inch) quick-release buckle is the same as found on mountaineering packs (i.e. Mountainsmith, Lowe Alpine, Greogory etc.) and is a "dual-adjust" model so the length can be adjusted from either right or left, keeping the buckle centered at all times. A Kinesis belt can be adjusted while it is worn in the fanny or belly position.

When you first put the belt on, place the buckle in the front... and then I slide the belt around so the buckle is in the back. The pouches surround the front and sides of you body, making them more accessible. Wear longer pouches, such as a water bottle pouch or E280 lens pouch on the sides and shorter pouches in the center. This makes it easier to lean or bend over.

A few customers have requested that their Kinesis harness work with the belt buckle in both the front and the back positions. See pig tail accessory below for a custom solution to this problems.

Sizing Notes
Order the same size as your pants waistband. Kinesis belts are sized to fit over normal streetwear, 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.
