Look elsewhere if you…

Buyers who need a different feature set, check the alternatives below.

What You Are Buying

The Easton is a 40 by 63 inch single panel with a grommet top, sold in a wide range of solid colors from black and charcoal through pastels aimed at nurseries and kids' rooms.

It is Sun Zero's entry-level line, positioned below the brand's Nordic and Kendrick panels, which use a heavier fabric and block closer to 99% of light.

The fabric is a tightly woven polyester rather than a laminated Thermaback-style backing.

This is the main reason for the gap between the Easton's 90% blocking and the 98%+ rates from Eclipse's Palisade or Darrell lines.

Performance

Light blocking in a dark colorway: In a charcoal or black panel, the room dims substantially, with a faint gray glow remaining rather than the near-total dark achieved by laminated panels.

This is a real difference at midday but is not noticeable at all for evening or early-morning light.

Light blocking in a light colorway: Pastel and light-toned Easton panels block noticeably less, closer to 80% to 85%.

For a nursery or kids' room where a lighter color is wanted for the room's decor, expect a visible strip of light along the fabric weave even with the panel fully closed.

What It Does Well

The price-to-performance ratio is the whole story here.

The color range is unusually wide for a budget line, covering both neutral tones for a main bedroom and softer pastels for a nursery.

What Falls Short

For a shift worker or anyone needing a genuinely dark room at midday, the Easton alone in a single layer will not fully replicate the darkness of a laminated Thermaback panel.

Doubling up panels closes most of the gap.

40-inch width requires planning.

A single panel does not cover most standard windows on its own.

Who Should Buy It

The Sun Zero Easton is right if: the budget is the primary constraint, the room gets moderate rather than intense direct sun, and a slightly-less-than-perfect blackout is an acceptable tradeoff for the price.

Consider alternatives if: the room faces intense direct sun, or if genuinely complete darkness during daytime hours is a hard requirement, in which case the Eclipse Palisade or Darrell's Thermaback backing is worth the extra cost.

Worth comparing

Answers

Frequently asked questions

Does the Sun Zero Easton really block 90% of light?

In a dark colorway (charcoal or black), yes, roughly in that range based on the woven construction. Lighter colors in the same line block somewhat less, closer to 80% to 85%, since less pigment in the fabric means more light passes through even with the same weave density. For the darkest room, choose the darkest available color.

Is one panel enough to cover a standard window?

Usually not on its own. At 40 inches wide, one Easton panel covers roughly the width of a narrow window when closed, but most standard bedroom windows (36 to 48 inches) need two panels, one per side, to fully overlap the frame and close the side light gaps that let in the most light.

How does the Easton compare to Sun Zero's other lines, like Nordic or Kendrick?

The Easton is Sun Zero's entry-level grommet and rod-pocket line, positioned below the Nordic and Kendrick lines, which use a heavier, more tightly woven fabric and typically block closer to 99% of light. The Easton trades some of that blocking performance for a lower price, which is the right tradeoff for a secondary bedroom, kids' room, or a budget-constrained main bedroom.

Is the Sun Zero Easton machine washable?

Yes, on a cold, gentle cycle, and it is best hung to dry rather than put through a hot dryer, which can degrade the blackout backing over time. Ironing on a low setting is generally fine if needed after washing.
