Sijo's Eucalyptus Bed Blanket is the value pick of the cooling-blanket category and the smartest TENCEL choice for hot sleepers who want a single blanket year-round. The eucalyptus-derived TENCEL lyocell weave is famously breathable — Apartment Therapy testers reported waking up sweat-free — and the cotton blend adds enough body that the blanket layers well over a comforter in winter. Sale pricing brings it under $100, which is exceptional value for an OEKO-TEX certified TENCEL blanket.
Full review
Cooling Performance in Hot Sleep
TENCEL lyocell from eucalyptus is widely considered the gold standard in cooling textiles, and the Sijo Eucalyptus Bed Blanket leans hard on that science. Apartment Therapy's reviewer described waking up "totally sweat-free" after sleeping under the Sijo line on hot summer nights — even the pillowcase from the eucalyptus collection "kept my head and the back of my neck dry overnight." The mechanism is moisture-wicking: TENCEL fibers can absorb up to 50% more moisture than standard cotton before feeling damp, so perspiration moves off the skin into the fabric and evaporates instead of pooling against the body. The Good Trade confirmed the blanket "doesn't get swampy in summer" across multi-week wear-testing.
Sleep Foundation has awarded Sijo's parallel comforter the Best Airflow Comforter trophy, and the bed blanket version uses the same 50/50 TENCEL-cotton weave. Hot sleepers in humid climates will get the most out of the eucalyptus's evaporative cooling — in dry desert air, the wicking advantage shrinks because there is no humidity to evaporate into. The 350 GSM weight is meaningfully heavier than gauze options like Quince's, so this blanket is more of a year-round single-blanket pick than a thin summer-only top layer.
Feel and Drape
The fabric uses a subtle waffle weave that adds texture and trapped airflow. Apartment Therapy's reviewer of the Sijo CLIMA comforter described the eucalyptus surface as "airy and weighted at the same time," with a "luxe, silky smooth exterior" — the bed blanket shares the same finish. The cotton blend gives the blanket more substantial drape than a pure-TENCEL knit would have, so it conforms to the body and stays in place during sleep instead of sliding off. Sijo offers the blanket in muted neutral colorways (Fog gray, Cream, Pearl) that fit modern interiors but limit decorative variety.
Construction and Materials
Sijo uses 50% TENCEL lyocell sourced from sustainably farmed eucalyptus and 50% cotton, woven at 350 GSM. The TENCEL lyocell process is closed-loop — the solvent used to dissolve cellulose into filament fiber is captured and reused at 99%+ efficiency — which makes it materially more eco-friendly than the open-loop viscose process used for bamboo cellulose. The blanket carries OEKO-TEX Standard 100 certification (consumer-health-safe) and FSC certification (responsible forestry on the eucalyptus side). For sustainability-minded buyers, this is the strongest credential set in the category.
Care and Durability
The biggest practical advantage Sijo's blanket has over competing TENCEL options like the Buffy Breeze (which is dry-clean only) is that it is machine washable. Cold water, gentle cycle, low tumble dry — the same care routine as standard cotton bedding. No fabric softeners, no bleach, no high heat. TENCEL is more wash-fragile than bamboo viscose so following the cold-water instruction matters, but owner reviews on Sijo's site indicate the blanket holds up to weekly washing without significant pilling or shrinkage.
Sizing and Coverage
Three sizes — Twin/Twin XL (66" x 90"), Full/Queen (90" x 90"), and King/Cal King (106" x 90"). The 90-inch length is shorter than Cozy Earth's 100-inch blankets, so tall sleepers or anyone who likes the blanket to tuck under their feet should account for the difference. The King size at 106 inches wide is generous and will drape past a standard king mattress edge by a few inches on each side. There is no oversized or California-king-specific option.
What Reviewers Loved
Apartment Therapy's hot-sleeper reviewer rated the broader Sijo Eucalyptus line as her all-time favorite for summer cooling, specifically calling out the lack of night sweats. The Good Trade described it as the rare comforter that "offers plenty of warmth during the winters without getting swampy in summer" — true year-round versatility. Tom's Guide's review of the matching mattress protector confirmed the line delivers "a cool, comfortable and noiseless sleep all night long." Sleep Foundation's earlier Best Airflow Comforter award for the Sijo line gives the brand credibility that newer eucalyptus competitors haven't earned yet.
Where It Falls Short
Color and size options are limited — three colorways, three sizes — so buyers wanting a specific accent shade will need to look at Brooklinen or Cozy Earth. The 350 GSM weight is meaningfully heavier than gauze blankets like Quince's, which makes it less suitable as a thin summer-only top layer over a comforter. In peak summer humidity (95°F+), some owner reviews note even the eucalyptus weave can feel warm if the room isn't AC'd. The blanket is brand-direct only — no Amazon listing — so there's no Prime shipping, and the trial period (30 days) is shorter than the Cozy Earth (100 nights) and Brooklinen (365 nights) competitors.
Who It's Best For
Hot sleepers in humid climates who want the cooling power of TENCEL eucalyptus without the dry-clean requirement of Buffy or the $359 price of Cozy Earth. The 50/50 eucalyptus-cotton blend is the right pick for buyers who want a single blanket that works alone in summer and layers under a comforter in winter. Sustainability-minded shoppers will appreciate the closed-loop TENCEL process and the FSC certification. Skip this blanket if you want a thin gauze top layer (go Quince instead) or you prioritize a frigid first-touch sensation from a PCM cover (Slumber Cloud).
How It Compares to Alternatives
Within the eucalyptus TENCEL category, Sijo's main competitor is the Buffy Breeze (which is technically a comforter, not a blanket — heavier construction, dry-clean only). Buffy is more of a year-round single-comforter solution; Sijo's Bed Blanket is more versatile as a layering piece. At roughly $115 list and $92 on sale, Sijo undercuts Buffy on price by 30-40% for what is functionally the same eucalyptus moisture-wicking technology.
Against the broader cooling-blanket market, Sijo's eucalyptus + cotton blend sits between Cozy Earth's pure-bamboo luxury at $359 and Quince's pure-cotton gauze at $80. It's the rare cooling blanket that delivers premium-tier cooling performance at upper-mid pricing while keeping the practical advantage of machine washability. Sleep Foundation's Best Airflow Comforter award for the parallel Sijo product confirms the brand's TENCEL implementation is among the best in the category.
Value at This Price
At $115 list (often $92 on sale), Sijo's Bed Blanket is roughly one-third the price of Cozy Earth's Bamboo Blanket while delivering arguably better moisture-wicking from the TENCEL lyocell fiber. The 30-day trial and 60-day return window are shorter than Cozy Earth (100 nights) or Brooklinen (365 days), so buyers have less time to evaluate, but the lower price point makes the buyer's risk lower in absolute dollar terms.
Sustainable-bedding shoppers get extra value here: closed-loop TENCEL production plus OEKO-TEX and FSC certifications combined add up to one of the stronger sustainability profiles in the category. Sijo's direct-to-consumer model keeps prices below comparable boutique brands like Coyuchi and Boll & Branch. The value case is strongest for hot sleepers who want premium-tier cooling without paying premium-tier prices, and don't need an oversized king or extensive color options. Sijo runs Memorial Day and Black Friday sales that typically discount the bed blanket 20-25%, bringing the queen size under $90.
Long-Term Durability
TENCEL lyocell holds up to repeated washing better than bamboo viscose or pure cotton — the closed-loop fiber process produces a stronger filament with less surface fraying. Owner reviews on Sijo's site indicate the bed blanket maintains its waffle-weave texture and dimensions through 50+ wash cycles without significant pilling. The 50/50 cotton blend does add some shrinkage risk over time; following Sijo's cold-water gentle-cycle care instructions is important. The blanket carries standard manufacturer defect coverage but no extended warranty against pilling or texture degradation, so buyers should expect a 3-5 year functional lifespan with weekly use, comparable to most mid-tier bedding.

Watch-outs
- −Available in fewer colors and sizes (3 sizes total) than premium bamboo competitors
- −The 350 GSM weight is heavier than gauze blankets, so it can feel warm in peak August humidity
- −Brand-direct only — no Amazon listing for the blanket, so no Prime shipping
How it compares
More breathable and lighter than the Cozy Earth Bamboo Blanket at one-third the price, but with less luxurious drape and a shorter trial period. Better cooling than the Luxome Lightweight Blanket because eucalyptus TENCEL outperforms standard bamboo viscose on moisture-wicking tests. Heavier and more substantial than the Quince Organic Airy Gauze Blanket, so it works as a standalone year-round blanket where the gauze quilt is mostly a summer-only layer.
