What They Have in Common
Both are full-surface mats with no offset hitting panel — you can stand anywhere and swing from anywhere. Neither has a replaceable strip, and neither maker publishes a swing guarantee. Both sit on a single uniform surface designed to take a real or insert tee. The list prices are within $31 of each other.
Where They Differ
Size and Thickness
The SIGPRO 3D 5×5 is 60 × 60 inches. The Fiberbuilt Performance Turf Tee Box 4×4 is 49 × 49 inches. That's 11 inches in each direction — enough that a wider-than-average stance or a step back for a driver is a different experience on the two mats. If you ever share the bay with someone who sets up well behind the hitting line, the extra room matters.
Thickness goes the other way. The Fiberbuilt is 2 inches thick; the SIGPRO is 1.6 inches. That 0.4-inch gap is worth knowing if you're placing a launch monitor on the mat, since the ball sits a little higher on the Fiberbuilt. Check the figure against your monitor's placement requirements before you decide.
Tee Setup
Fiberbuilt's approach is simple: real tees go straight into the all-nylon turf, anywhere on the mat. No inserts, no adapters. The SIGPRO takes the opposite route — four fixed tee-insert holes, and you'll need a tee designed for them (the brand mentions options like the Tomahawk NEO, Bir-Tee, or TeeClaw). Neither is wrong, but they suit different preferences. If you hate hunting for an insert before every range session, the Fiberbuilt's push-anywhere approach wins. If you like a consistent tee location and already have insert-style tees, the SIGPRO works fine.
Outdoor Use and Material
The SIGPRO is rated waterproof and built for commercial high-volume use, with woven turf on a waterproof polyurethane glue over a layer of elastic fibers. It'll live outside. The Fiberbuilt uses UV-resistant all-nylon turf on a modular rubber foundation and is listed for indoor or outdoor use too — Fiberbuilt just doesn't call it waterproof.
Warranty and Weight
Fiberbuilt publishes a 1-year warranty on the turf and a 5-year warranty on the rubber base. The SIGPRO 3D 5×5 comes with no published warranty — The Indoor Golf Shop doesn't list one. The SIGPRO also has no published weight; the Fiberbuilt is 72 lbs. If you're moving the mat around your garage regularly, the SIGPRO is an unknown quantity on that front.
Who Should Buy Which
Get the SIGPRO 3D 5×5 if:
- You want the larger footprint (60 × 60 vs. 49 × 49) for ~$31 more at list
- The mat will live outdoors or in a covered area that sees weather
- You're outfitting a commercial or high-traffic hitting bay
- You already use insert-style tees and prefer a fixed tee position
Get the Fiberbuilt Performance Turf Tee Box 4×4 if:
- Floor space is limited and 49 × 49 covers what you need
- You want a documented warranty — the 5-year coverage on the rubber base is a real differentiator
- You prefer pushing a real tee into the turf anywhere you like, without adapters
- You need to know the weight before buying (72 lbs vs. no published figure for the SIGPRO)
The Bottom Line
Thirty-one dollars at list separates these two, and the SIGPRO 3D 5×5 uses that gap well — more surface, outdoor-rated construction, and commercial-grade build. The trade-off is a thinner profile, no published warranty, and no published weight. The Fiberbuilt Performance Turf Tee Box 4×4 is the one to grab if the warranty matters or space is tight. For most buyers setting up a permanent hitting bay who want room to move, the bigger mat is the right call.
