The details

Everything the short page leaves out.

The numbers, the drawing set, the fit check, the two states, theater mode, the comparison, what it is made of, and how the reservation works. A freestanding golf simulator enclosure that folds flat against the wall in under a minute. List $2,495; the first 25 at the founders price of $2,295; a $100 refundable reservation holds a numbered slot.

Tested with real swings on the July prototype; the factory sample's own strike test and timed folds post to the waitlist first, pass or fail. Every part on the sheet is a real, named, replaceable component. This is equipment, not a tent.

Will it fit?

Check your space in ten seconds.

The bay plays at about 10' wide and folds flat against the wall when you're done. Garage, spare room, office, covered patio: punch in the space you have and see exactly how much of it you get back.

Fits, with a couple tradeoffs
■ folded · flat to the wall■ to play ~11 ft┊ your depth 20 ft
  • Folded, the bay sits flat against the wall: about 20 inches off the wall on the factory sample as shipped; production bases get a U-slot so the frames nest to about 12 inches. The rest of the depth comes back.
  • 8.5 ft ceiling clears the 7.5 ft frame; a 9 ft ceiling gives a driver swing more headroom.

Theater mode · after hours

Lights down.
The screen stays up.

Fold the bay away and the impact screen stays standing on its own frame: a ten-foot projection wall for movie night, the game, or a race. Rival folding sims lace their screens into the panels, so folding kills the screen. Ours doesn't.

Vs. the alternatives

The only one that does all five.

A mounted retractable does give the floor back when it is rolled up. It is fixed to the wall or ceiling where it was installed, which is the real difference. The alternative most people settle for: giving a whole room or the parking spot to a permanent build, or a DIY fold-away wall. See the full comparison, with sources.

On the record

What it's made of, on the record.

Named, specified, published

Every material in the kit is named and specified: the fabric weight, the grommet type, the stitch standard. If a sim enclosure won't tell you what its screen is made of, ask why.

A measured screen

A 10 foot by 7 foot 6 hitting screen, measured on the real build, not a CAD promise. The production screen is in test; the sample hangs my own Carl's.

Ships in cartons

The factory sample arrived in cartons by parcel carrier, no freight truck. Carton count and weights get published from the sample, measured, not estimated.

The first sample, in public

Delivered October 8, built October 10, played October 11. What passed, what did not and what changes before production is posted either way.

Screens are consumable

Impact screens wear. Every brand's does. Ours is a standard, replaceable part, not a reason to buy a new enclosure.

Founder, not a call center

You're buying from the person building it. Founders get a direct line to the build, and if the bay isn't right, we sort it out personally.

Founders Reservation

Reserve a numbered build slot.

The waitlist is the door: free, and it gets the scorecard and the build schedule first. The Founders Reservation is the seat: $100, refundable, one of 25 numbered build slots at the founders price of $2,295 (list $2,495).

before your build ships

The reservation locks the founders price: $2,295 instead of the $2,495 list, and your $100 credits toward the final invoice. First 25 builds only. At unit 26, the price returns to list.

Secure Stripe checkout · opens in a new tab · $100, refundable

Refundable anytime before your build ships. Reply to your confirmation email, or email hello@stowgolf.com, and the full $100 goes back to your card. No restocking fee, no forms, no store credit.

Stock lands in Tempe around early January if the order goes in on schedule. Reservation holders get the dated build schedule first, and your $100 stays refundable the whole way.

Real footage · July prototype · shown at 4xFull speed: 45 seconds, timed on camera, first attempt

Every fold, stow, and impact demonstration on this page is real footage of our own units, the July prototype and the October factory sample, with any speed change labeled on the clip. Concept renders are labeled as renders. We would rather be slower and real than fast and faked.
