Do I have to buy the sizing kit?
No you don't have to purchase the sizing kit. We strongly encourage using a full sizing kit whenever possible because correct sizing is extremely important to how the Grip functions. Proper fit affects both comfort and security, especially the glans ring sizing. Many sizing problems come from users choosing sizes larger than they actually need.
You do not have to purchase the official HZD sizing kit in order to determine your sizing. If you have access to a 3D printer, all of the sizing kit STL files are available for free through our MakerWorld page:
https://makerworld.com/en/@hzdgrip
The downloadable files include:
- Glans sizing rings
- Shaft sizing tubes
- Shaft length measurement tools
If you would prefer an easier way to measure, we offer a complete sizing kit that includes professionally printed rings, tubes, and a shaft length tool ready to use out of the box.
The official sizing kit also includes a $10 coupon code (https://headzonedefense.com/products/sizing-kit) that can be applied toward your future HZD order, helping offset much of the cost of the kit itself.
International Sizing Kits & Community Printers
We also have community members in several countries who locally print and sell sizing kits to help reduce international shipping costs and delays.
You can find the current list of community printers here:

These community-run options can make obtaining a sizing kit significantly easier for international customers.
