Made to endure

The majority of materials we use for our commercial production are the same which we use in equipment for the Finnish Defence Forces and other defence and security clients. Our most commonly used fabric in load carrying equipment is extremely wear resistant 1000D Cordura, as per FDF specs, with polyurethane coating on the inside. The webbing and edge tape we use are, again as per FDF specs, strong polyester webbing in various widths and thicknesses for different applications.

Our green and M05 camouflage materials and accessories are by default compliant with strict FDF specs for NIR reflection levels, as should be since these same materials are used in official military equipment.

Fast & Reliable USA Delivery

Vanguard Yard is a trusted outdoor equipment store based in the USA, proudly serving customers nationwide. With our dedicated US warehouses, we ensure fast and reliable delivery on every order, backed by excellent customer service.

Lightning-Fast Delivery & Incredible Power

"I couldn't believe how quickly my new zero-turn mower arrived—having dedicated US warehouses makes a huge difference! The cutting power is incredible, and it was ready to go right off the pallet. Vanguard Yard definitely provided the most competitive price and service out there."

— Mike T.

Ready for Winter & Built to Last

"I ordered a 2-stage snow blower and it arrived at my door in just three days. The heavy-duty build quality is obvious right out of the box, and it chewed through our first big storm effortlessly. I was worried about shipping such a large machine, but Vanguard Yard's domestic freight was seamless. Highly recommend!"

— Mark D.

Premium Quality and a Massive Hit with the Kids!

"We bought a wooden swing set for our backyard and the quality is absolutely exceptional. Real, sturdy wood and commercial-grade hardware. Shipping was surprisingly fast from their US warehouse, and everything arrived exactly as described. Worth every penny for this level of durability."

— Sarah T.

Commercial Grade Power at a Fair Price

"I upgraded to a 3000 PSI pressure washer kit from Vanguard Yard and couldn't be happier. It cleans my driveway and siding just like a professional unit. Fast shipping, great packaging, and the machine has incredible power. This is officially my new go-to store for property maintenance gear."
