The Eclipse Fresno is the proven-blackout specialist, laboratory-tested to block 98-99.9% of sunlight via patented Thermaback construction. Bob Vila praised the Eclipse line for blocking 'nearly all sunlight, even in the middle of the day,' and reviewers note no light bleed from the edges, no chemical smell, and roughly 40% noise reduction. It is sold as single panels with a rod-pocket header, but for a thick, durable, near-total blackout panel at around $40, it is excellent.

Real-World Light Blocking
The Eclipse Fresno is built on Eclipse's patented Thermaback (Thermaweave) technology, and it is laboratory-tested to block between 98% and 99.9% of sunlight and harmful UV rays. That figure is backed up by hands-on reviews: Bob Vila, testing the Eclipse line, reported it 'blocked out nearly all sunlight, even in the middle of the day,' the toughest scenario for any blackout curtain.
Reviewers also emphasize what the spec sheet does not capture, the absence of light leak. One noted the Fresno has 'no light bleeds from the edges,' which is often where cheaper blackout curtains fail. Combined with the near-total fabric blocking, the Fresno delivers a genuinely dark room, landing just behind the flashlight-test-winning NICETOWN and the Reviewed-topping Amazon Basics.
Construction and Materials
The Fresno is 100% polyester built with Eclipse's triple-weave Thermaback construction, the dense, layered weave that does the light-blocking and insulating work. Reviewers describe the fabric as 'thick and very durable with strong stitching,' and note there is 'no chemical or plastic smell,' a common complaint with cheaper coated blackout curtains that the Fresno avoids.
It uses a rod-pocket and back-tab header rather than grommets, which gives a clean, gathered look and lets the panel sit flat against the window for better edge coverage. The trade-off is convenience: rod-pocket panels are slightly more fiddly to open and close daily than the gliding grommets on the NICETOWN and Amazon Basics.
Thermal and Noise Benefits
The Thermaback construction is engineered as much for insulation as for light. It 'offers thermal benefits while providing an insulated barrier against summer heat and winter chill to balance room temperature and save on energy bills,' which makes the Fresno a strong choice for drafty or sun-baked windows.
On noise, the Fresno is laboratory-tested to reduce ambient sound by around 40%, and reviewers confirm it is 'capable of blocking out road noise and nature sounds.' The dense triple-weave that blocks light also absorbs sound, so the Fresno delivers the full blackout-thermal-noise trifecta in one panel.
Durability and Everyday Use
Durability is a recurring theme in Fresno reviews. The fabric is thick and the stitching is strong, and one reviewer summarized being '100% satisfied' after the curtains held up to use. For a budget panel, it feels built to last rather than disposable.
Day to day, the Fresno is sold as a single panel, so you will need two (or more) to cover a standard window, a detail to factor into the price. Once hung, the rod-pocket header keeps the panel flat against the wall, which actually helps with edge light leak compared with grommet panels that bow slightly away from the window.
How It Compares to Alternatives
The Fresno's 98-99.9% light blocking puts it in the top tier of this list, just behind the NICETOWN Contemporary Lined Blackout (which won CNN's flashlight test) and the Amazon Basics Room Darkening Blackout (which topped Reviewed.com), and on par with the Best Home Fashion Premium Blackout's 99%. All four are genuine blackout performers; the Fresno's edge is its lab-validated near-total blocking and its no-light-bleed edges.
Its main differentiator versus the top two is the header. The Fresno uses a rod-pocket/back-tab design rather than the grab-and-go grommets on the NICETOWN and Amazon Basics, which trades daily convenience for flatter, better edge coverage. And it vastly outperforms the room-darkening Sun Zero Barrow, which only reduces light. The Fresno is the pick for buyers who prioritize proven, near-total blocking over header convenience.
Where It Falls Short
The Fresno is sold as single panels, so the advertised price covers one panel and you will typically need at least two to cover a window, effectively doubling the cost versus the two-panel sets from NICETOWN and Amazon Basics. Factor that into the comparison.
The rod-pocket and back-tab header, while good for edge coverage, is less convenient than grommets for opening and closing the curtains every day, and the stiff theater-grade fabric drapes less softly than lighter curtains. As always, lighter colors block less light than the darker options, so choose a dark colorway for maximum blackout.
Who It's Best For
The Eclipse Fresno is the right pick for shoppers who want a thick, durable, near-total blackout panel with strong thermal and noise benefits and no light bleed at the edges, and who do not mind a rod-pocket header or buying single panels. It is especially good for drafty or noisy windows where the insulation and sound reduction earn their keep.
It is a weaker fit for those who want grab-and-go grommets and two-panel value (the Amazon Basics Room Darkening Blackout), the flashlight-test-validated darkest option (the NICETOWN Contemporary Lined Blackout), or decorative styling (the Best Home Fashion Premium Blackout).
Strengths
- +Laboratory-tested to block 98-99.9% of sunlight and UV rays, with patented Thermaback/Thermaweave construction
- +Bob Vila named the Eclipse Microfiber line 'Best Lightweight,' blocking 'nearly all sunlight, even in the middle of the day'
- +Reduces noise by around 40% and insulates against summer heat and winter chill
- +No chemical or plastic smell, with reviewers reporting no light bleed from the edges
- +Thick, durable fabric with strong stitching at a budget price
Watch-outs
- −Sold as single panels, so you need two (or more) to cover a typical window
- −Rod-pocket/back-tab header is less convenient than grommets for daily opening
- −Lighter colors block less light than the darker options
- −Stiffer 'theater-grade' fabric drapes less softly than lighter curtains
How it compares
Its near-total light blocking puts it just behind the NICETOWN Contemporary Lined Blackout and Amazon Basics Room Darkening Blackout, and on par with the Best Home Fashion Premium Blackout. Its rod-pocket/back-tab header is less grab-and-go than the grommets on the NICETOWN Contemporary Lined Blackout and Amazon Basics Room Darkening Blackout, and it blocks far more light than the Sun Zero Barrow.
