The weight of your camera and heaviest lens should determine the size of the camera strap pad. UPstraps come large, XX, medium and small pad. All UPstrap non-slip shoulder pads are molded directly to the webbing. All attachment hardware is included. Quick releases are available for the large and medium pads but not the small pad.

To determine the most comfortable pad . . . know the combined weight of your camera and heaviest lens.

The LARGE DSLR. . . . .generally best for . . . .a load starting at 4-8 pounds / 1.8 -3.6 kilograms.

The The X-PAD . . generally best for . . . .a load starting at 2-3 pounds.

The MEDIUM SG generally best for . . . .a load starting at 2-4 pounds /.8-1.8 kilograms

The SMALL RF/DC PAD . . . . . generally best for . . . a load starting at 14 oz / .4-1 kilograms

We do our best to provide realistic estimates but the upper shoulder weight comfort limits are user dependent.

The pad size is about comfort. Tensile strength is not an issue . . .if you can carry it the UPstrap can hold it.

To determine the best web for your camera . . . know the strap attachment system your camera uses.

Nylon web is best for cameras with smooth split rings. Kevlar web is best for cameras with abrasive brackets or slots. Most Nikons will have a split ring attachment. Canons will have a slot or bracket attachment.

A quick release option is available to detach the strap pad and the majority of the web. Only the quick release ends remain attached to the camera. There is a wrist loop, handle, bandolier and shoulder harness options for various carry applications.

Both 3/8" nylon and 1/2" kevlar web will fit 99% of all cameras.

Be mindful that the choice of a pad may have more to do with the weight of the lens. There are crossover areas where a mid size pad will do fine for your normal carry lens but a larger pad is a better choice for your camera and heavier lens. This is a judgement call on your part. If your not sure which way to go order both and return the one you don't want.
