The Weber 7139 is the OEM cover Weber currently ships for Spirit 300 series (pre-2025) and Spirit 400 four-burner grills. It is what you buy when you own a current-model Weber Spirit and want a tailored sleeve that looks like it belongs on the grill rather than a baggy universal cover. Bob Vila's 2026 review highlights the same Weber Premium line as the pick for Spirit owners, and notes that the polyester construction with woven UV inhibitors holds up notably better than the rubberized fabric Weber used on its older Genesis-era covers (which AmazingRibs Pitmaster Club members repeatedly flagged for cracking after two seasons).
Full review
Fit and Sizing
The 7139 measures 52 inches wide, 27 inches deep, and 42 inches tall out of the carton, which is the size Weber set specifically for the Spirit 300 three-burner with side-mounted controls (model years 2016 through 2024), the new Spirit 4-burner (2025 and later), and the pre-2016 Spirit 2-burner. If you own one of those grills the cover slips on like a sleeve and the seams line up exactly with the cart edges, with no sag and no overhang at the wheels.
Compatibility is also the cover's biggest limit. The 7139 does not fit the Genesis II 300 series (that is the 7130 in Weber's lineup) and does not fit the new 2025 Spirit if it has front-mounted controls, because the depth dimension changed. Weber's compatibility article (consumer-care.weber.com) is unusually clear about this, so check your grill's serial-plate model number before ordering.
Material and Weather Resistance
The 7139 is 100% polyester with UV inhibitors woven directly into the fabric rather than sprayed on as a coating that wears off. Weber's product page describes the cover as breathable and water-resistant. In practice the breathability is real, which is why Weber owners do not see the heavy condensation buildup that PVC-coated covers produce when you put them on a still-warm lid.
The water resistance has been described inconsistently in forum reports. Bob Vila tested the Weber Premium line over a year of use and reported it kept the grill dry through tropical storms. Other AmazingRibs forum users described water pooling on the flat top section of the lid through the cover after extended downpours. Best practice: avoid putting the cover on while the grill is still hot (steam wicks through both directions) and shake water off the top before lifting.
UV Resistance and Cold Weather
Polyester with woven UV inhibitors is where the 7139 most clearly out-performs cheaper vinyl and PVC-coated covers. Vinyl covers crack at the seams when temperatures drop below freezing, then admit water into the foam interior of a Weber lid. The 7139's polyester stays pliable into single-digit Fahrenheit temperatures, which is why Weber explicitly markets it for year-round outdoor storage in northern climates.
Long-term color retention is reasonably good for the all-black colorway. Two-season comparisons in the AmazingRibs Pitmaster Club forum showed Weber Premium covers fading less visibly than Char-Broil's basic vinyl cover, which often takes on a chalky surface bloom after a full summer. The trade-off is that black absorbs more heat in direct sun, which can accelerate fabric breakdown at the very top of the cover compared with a lighter-color competing cover.
Tie-Down and Wind Performance
The 7139 uses Velcro fastening straps that wrap around the cart legs rather than the click-close buckles and hem cord that Classic Accessories ships on the Veranda. This is a step down in wind security; the straps work for normal weather but several forum users reported having to retighten the Velcro after big gusts because the hook-and-loop loses grip over time.
The cover is heavier and more tailored than universal alternatives, which helps wind performance independently of the strap system. Because the sleeve hugs the grill cabinet rather than draping loosely, there is less air space for wind to inflate. For owners in wind-prone areas, AmazingRibs commenters frequently recommended adding a bungee cord under the cart as a belt-and-suspenders solution.
Warranty and Long-Term Durability
Weber's three-year limited warranty is the longest of the five covers in this comparison, and Weber consumer support honors it without requiring proof of purchase in most reported cases (forum users routinely cited Weber sending replacement covers based on a serial-plate photo). That is meaningfully better than Classic Accessories' two-year coverage and Char-Griller's case-by-case warranty handling.
Real-world service life from long-form reviews and forum reports is typically three to five years, with the polyester staying intact and the seams holding. The most common failure mode is the Velcro losing grip first, after which the cover still works but needs a bungee cord assist. Bob Vila's contributor reported a Weber Premium cover surviving multiple tropical storms in one year of testing without seam failures.
Where It Falls Short
The 7139 has three real weaknesses. First, fit specificity: it is engineered for Spirit 300/400 only and is useless on any other Weber line (Genesis II, Summit, Q-series) or any non-Weber grill. Second, water resistance is not waterproofing; pooled water on the flat lid section can wick through over several hours of standing exposure, where a fully PVC-coated cover like the UNICOOK would shed it. Third, the Velcro strap system is less secure than the click-close buckles plus hem cord on the Classic Accessories Veranda.
It is also priced higher than universal alternatives at roughly $90 versus $40 to $55 for a Char-Broil or UNICOOK universal cover. The premium is justified for tailored fit and three-year warranty, but if you only need basic weather protection and want to spend $40, this is not the value pick.
Who It's Best For
The 7139 is the obvious pick for owners of a current-model Weber Spirit 300 three-burner (2016 to 2024), the new 2025 Spirit 4-burner, or the pre-2016 Spirit 2-burner with side-mounted controls. The tailored fit, three-year warranty, and polyester cold-weather performance are exactly what those owners want, and the OEM-matched look beats a baggy universal cover by a noticeable margin.
It is not the pick for Genesis II owners (look at the 7130 instead), Summit owners (different cover entirely), or non-Weber owners (the Veranda 73912 wins for universal fit). It is also not the pick if you specifically need a fully waterproof PVC-coated cover for tropical-rain conditions; the UNICOOK Heavy Duty Waterproof is the right pick there even on a Spirit.
Air Vents and Mold Prevention
Weber does not advertise integrated air vents on the 7139, but the polyester fabric is genuinely breathable rather than vapor-sealed, which functions as continuous low-rate ventilation across the whole cover surface. This is the right structural choice for a gas grill that holds residual heat for hours after a cook: a fully sealed PVC cover would trap rising water vapor inside and condense it onto the cooking grates and burner tubes, accelerating rust on cast-iron components.
Multi-season Weber owners in humid Southeast climates have repeatedly reported less interior mildew and surface rust with the polyester 7139 than they saw with older PVC-coated covers. The trade-off is the cover is not as fully waterproof as a PVC alternative, which is what the breathability buys you. If you intend to put the cover on a still-warm grill regularly (within an hour of finishing a cook), the 7139 handles that better than UNICOOK's vinyl-coated alternative.
Value at This Price
At roughly $90 the 7139 is the most expensive cover in this comparison aside from the Kamado Joe, and that price premium has to be justified by the tailored fit, the three-year warranty, and the OEM-matched look. For Spirit owners those three together usually pencil out: the tailored sleeve looks visibly cleaner on the grill than a baggy universal cover, the three-year warranty is the longest available, and Weber consumer support honors it readily without requiring proof of purchase in most reported cases.
Versus universal alternatives at half the price, the case is closer. The Classic Accessories Veranda 73912 at roughly $55 has heavier fabric construction, padded handles, and a click-close buckle system that arguably beats the 7139's Velcro straps. The UNICOOK Heavy Duty at $44 is more fully waterproof. The Weber 7139 wins on tailored fit and warranty length but loses on fabric weight and waterproofing. Spirit owners who prioritize aesthetics and OEM warranty coverage should buy the 7139; Spirit owners who prioritize fabric weight or waterproofing should consider the alternatives.

How it compares
Tighter, more tailored fit than the universal Classic Accessories Veranda 73912 if you own a current-model Weber Spirit, but useless on any other brand. Better cold-weather performance than the UNICOOK Heavy Duty universal because polyester stays pliable below freezing while the UNICOOK's vinyl coating gets stiff. Three-year warranty is the longest of the five covers in this comparison.
Who this is for
