Sizing specifications for T3000, T3001, T3002, T3003 – Dive Rite TransPac Harness System

The TransPac harness is available in a wide range of sizes. Please carefully take the actual measurements explained below to make sure you select exactly the right size. As a starting point for most people, consider what size t-shirt you normally wear. If you wear a men’s Large T-shirt, then a Large TransPac is probably the best fit. If you wear a men’s XL T-shirt, then choose an XL TransPac; and so on.

Shoulder Strap: *To ensure proper shoulder strap length, measure from a point at the top of your shoulder to a point at your waist that is immediately below your shoulder, as shown in the diagram below.

Note: Make sure you allow for exposure suit thickness.

Lumbar Support Back pad and Soft Back plate: The Standard lumbar back pad and soft back plate is the size that most often fits average build men with back-of-neck measurements greater than 17 inches. XS/Small size TransPac harnesses come with Short lumbar back pads and soft backplates that are 2-inches shorter than those of larger TransPac harnesses. This is the preferred size for any diver whose back-of-neck to waist measurement is less than 17 inches (a range that includes most women). Dive Rite also offers Tall versions of the XL and XXL TransPac harnesses with long lumber back pads and soft backplates that are 2-inches longer than the standard size. The Tall versions are for divers who are over 75-inches in height.

Cummerbund -- TransPac harnesses come with a padded cummerbund whose length is adjustable across size range that is in proportion to the length of the shoulder strap. The top edge of correctly positioned cummerbund will just cover the navel, not rest on the hips.
