SeriousKit Harnesses are available in black or white silicone and are compatible with our full range of hand-pump cylinders and SPTs. Our harnesses can also be used with Venus 2000 or Trembler Receivers.

Ensure the perfect fit:

Sizing: Standard – up to 40″/100cm   Large – over 40″/100cm

SeriousKit users: At checkout use the ‘Order Notes’ section to let us know what SPTs\Hand-pump cylinders you will be using, including their internal diameter. There is some variation in the external diameter of our tubes from one model to the next and although the harness material is stretchy so it is possible to use each harness with a variety of tubes, we want to be sure you will get the right fit.

Venus 2000\Tremblr users: Use the ‘Order Notes’ section on the checkout page to let us know the external diameter of the receiver/s you are using.
