Grav Labs is the Austin, Texas glass company behind the original Gravitron, and it has been turning out borosilicate pipes, bubblers and bongs since 2004. What began with a handful of glassblowers who were sick of smoking out of two-liter bottles is now a full catalog of everyday cannabis hardware.
About the brand
David Daily and a crew of glass artists founded Grav in Austin in 2004, with Brandon Miranda as co-founder and glassmaker Micah Evans on the bench. Twenty years and a 20th-birthday capsule later, the team still runs on one idea: design the object people actually reach for, then build it to last.
What they make
The catalog covers the full glass range — bongs and gravity bongs, dab rigs, bubblers, hand pipes and one-hitters, plus bowls, bangers and replacement parts. Grinders, dugouts, papers and cones fill in around it, and there is a merch side too, from tees and posters to a zine.
The Gravitron is the signature piece, the original gravity bong the brand is known for, still sold in medium and large and given its own collection on the shop. Around it sits a rotating top-shelf tier for people who want something heavier than a daily driver.
The specifics
Borosilicate is the main material across the glass line, and pieces are spec'd down to the detail: joint sizes in 10mm and 14mm, male and female fittings, bowl capacity, height and width listed on every product page. Colorways run clear, amber, pink, lake green, smoke and light cobalt.
The newest line steps off the glass shelf entirely. Grav Cannabis Spirit is a non-alcoholic spirit distilled from single-strain fresh flower and water, carrying hemp-derived delta-9 THC, CBD and full-spectrum terpenes. Labeled potencies run from 2mg to 50mg per serving, and it is not sold into Alaska, California, Idaho or Oregon.
Culture
The collab shelf tells you where Grav's head is at: DGK and LRG on tees and a Hustle Trees bubbler, artist work from Savina Monet, a shirt and a zine with cartoonist Box Brown, a Flower Is Female poster. Skate, streetwear and print, rather than a corporate co-branding exercise.
That posture is written into the company's stated values too — come as you are, be a rebel, humble swagger — and framed openly as a stand against the corporatization of both Austin and weed. Standing discounts for teachers, medical workers, military and first responders back it up better than a slogan would.
The High Rise take
Grav is the safe recommendation that also happens to be the right one. A pocket bubbler at $45 with a listed joint size and a 3.25-inch stem is a piece you can hand a beginner without apology, and the top-shelf and collab pieces leave a collector somewhere to go.
Where to get it
Grav sells direct through its own shop with free shipping over $50 and a rewards program, and runs a wholesale lane for shops that want to carry the glass. Support is reachable by phone and email, and breakage is handled under a published shipping and replacements policy.
