Atarashi Wide Sleeping Bag (ASIN B08XW72H9T) is a semi-rectangular 3–4 season bag with 400GSM polyester fill, a 290T nylon DWR shell, a 40 x 87 inch Wide cut, right zip, and an included compression sack, listed for 32–77°F (0–25°C) comfort.
Atarashi targets side sleepers who want elbow room without buying a double bag, with a half-circle hood, draft collar, and right zipper that pairs with a left-zip Regular Atarashi for couples.

On a Smokies shuttle hike last October, I felt every ounce of the 6.3 lb whole-package weight. That night at a drive-up site, the 40-inch wide cut let my side-sleeping friend stop fighting mummy taper.
Nate Holloway's Verdict
Bottom Line
Atarashi Army Green Wide (B08XW72H9T) fits side sleepers and double-zip campers who accept 6.3 lb, not ultralight thru-hikers or hard-freeze car campers.
At ~4.5 stars with 40 x 87 in dimensions (July 2026), it fits forecasts inside 32–77°F when your sleep system is honest.
I'd verify live price and zipper orientation before checkout. Specs beat marketing copy every time.
This is not the 0°F Teton at best sleeping bags review. Step up when freeze nights are the plan.
I pair any budget bag with how to pick camping gear and car camping tips before I trust a rating label.
Best For
- Side sleepers who need knee and elbow room in a 40 x 87 in semi-rect cut.
- Campers pairing this right-zip Wide with a left-zip Regular from our Army Green Atarashi review or Purple Regular review.
- Drive-up trips when 6.3 lb stays in the car or covers a short hike-in.
- Shoulder-season forecasts between 32°F and mild summer nights.
Skip If
- You need sub-3 lb weight for multi-day backpacking.
- You need verified 0°F cold-weather room (Teton sibling instead).
- You want the lighter 4.2 lb Regular cut at 33 x 87 in.
- You are counting on Wide size to fit campers taller than 5'11".
Pros
- 400GSM polyester fill with draft collar and full-length draft tube. Listing targets tucked-in warmth on cool nights when you cinch the hood.
- 290T nylon shell with DWR finish. Shrug off light moisture better than bare polyester rectangles at this price.
- 40" x 87" wide semi-rect cut with stash pocket. Side sleepers can shift without fighting mummy taper.
- Right zipper pairs with left-zip Regular bag. Zip two Atarashi sizes into a double when orientations match per listing.
- Included compression sack. Stuff from the foot and tighten straps for trunk or vestibule packing.
- Machine washable per listing. Front-loader warm or cool cycle; tumble dry low with dryer balls.
Cons
- 6.3 lb whole-package weight. Roughly 1.5 lb heavier than Regular siblings; I would not carry this on a long trail.
- 32–77°F listed comfort range. Not a substitute for the Teton 0°F sibling on hard freeze trips.
- Wide does not raise height cap. Listing still fits up to 5'11", same as Regular size.
- Budget-tier zippers and fill. Fine for occasional trips; not expedition hardware.
- Right-zip only on this Wide listing. Left-zip partners must match ASIN before buying doubles.

Nate Holloway's Opinion
I'd grab B08XW72H9T when my partner needs 40 inches of shoulder room and the bag rides in a car, not on my frame for twenty miles.
I'd skip it when I'm counting ounces on a multi-day route and I'd rather sleep diagonal in a lighter mummy.
I've loaned the Wide cut to a side sleeper who stopped waking up cramped; we've slept better above 32°F with a real pad underneath.
Amazon Reviews
Buyer praise: roomy wide cut, warm for the price, decent compression sack, zips to partner Regular bag, fine for casual hiking.
Recurring gripes: heavy for backpacking, not deep-winter warm, height limit surprises tall buyers, zipper snags on budget hardware.

vs Teton Celsius XXL: Teton wins on 0°F cold car-camp warmth. Atarashi Wide wins on price for milder forecasts.
Choose Atarashi B08XW72H9T if: side sleeping, double-zip pairing, and 40-inch width beat 6.3 lb on your trip type.
Choose Regular B08XVMHB7J if: you want the same fill at 4.2 lb and 33-inch width.
Choose Teton Celsius XXL if: verified 0°F synthetic warmth matters more than ounces.
Care Checklist
- Fluff the bag before bed so 400GSM fill lofts fully.
- Use an insulated sleeping pad; ground cold steals warmth faster than air temp.
- Machine wash front-loader per listing; tumble dry low with dryer balls.
- Dry completely before stuffing; follow how to roll a sleeping bag for short trips.
REI's sleeping bag care guide covers drying and storage basics.
Final Thoughts
Buy if you want verified wide semi-rect 3–4 season room near budget Atarashi pricing and accept 6.3 lb on your trip.
Skip if ultralight trail weight, 6 ft+ height needs, or hard freeze nights drive your decision. The Teton Celsius XXL sibling covers cold drive-up trips; Regular Atarashi covers lighter weight.
Fluff it at home once so stuffing the sack feels familiar before your first cool night.
