FAQ
What types of products does GuardReady sell?
GuardReady offers equipment and accessories for fencing, kendo, iaido, HEMA, safe sparring, and general swordsmanship training. Our selection includes practice weapons, protective gear, uniforms, replacement components, equipment bags, maintenance supplies, conditioning tools, and club training equipment.
How do I choose the correct size for protective gear or apparel?
Sizing can vary between products and manufacturers. Review the measurements and sizing information shown on the individual product page before ordering. If you are between sizes, compare your measurements carefully and consider how much room you need for additional protective layers.
Is this equipment suitable for beginners?
Many products are suitable for beginners, but suitability depends on the discipline, age, experience level, and intended training activity. Beginners should follow the recommendations of a qualified instructor or club before purchasing weapons or protective equipment.
Can fencing, kendo, iaido, and HEMA equipment be used interchangeably?
Generally, no. Each discipline has different equipment standards, techniques, and protective requirements. Only use a product for the activity stated in its description, and confirm compatibility with your instructor, club, competition organizer, or governing body.
Is your equipment approved for competitions?
Competition requirements vary by discipline, organization, country, and event. A product should not be assumed to be competition-approved unless this is clearly stated in its description. Always confirm current equipment requirements with the relevant event organizer or governing body before purchasing.
Does protective equipment eliminate the risk of injury?
No. Protective equipment may help reduce certain risks, but it cannot prevent every injury. Inspect all equipment before each use, train under appropriate supervision, follow established safety rules, and replace any item that is damaged, worn, altered, or no longer fits correctly.
Are the training swords and weapons sharp?
Products are sold according to the specifications stated on their individual product pages. Some items may be blunt, padded, synthetic, wooden, or designed only for controlled practice. Always read the complete description and never assume that an item is harmless. Handle and store all training weapons responsibly.
How long does shipping take?
Order processing and delivery times vary depending on the product, destination, carrier, and availability. Tracking information is normally provided after shipment. Please review our Shipping & Delivery page for current details and allow additional time during holidays, severe weather, or carrier disruptions.
Can I return or exchange an item?
Eligible items may be returned in accordance with our Return & Refund Policy. Items should generally be unused, unmodified, and returned with their original packaging and components. Contact us before sending anything back, as unauthorized returns may not be accepted.
