From backpacking trips to car camping excursions, the Boost 650 provides the dreamy comfort you need to sleep well outdoors. With an innovative design that allows you to adjust its shape and add warmth when needed, the Boost is one of the most comfortable and versatile sleeping bags ever made. The semi-rectangular shape gives you considerably more internal space than a mummy bag—you’ll feel unrestricted and free to sleep in whatever position you want all night long. But more space demands more body heat to warm it up and cold isn’t comfortable. That’s where WarmZip comes in. Zipping up the WarmZip center zipper transforms the shape of the Boost 650 from a semi-rectangular bag to a thermally efficient mummy bag. It pulls the 650-fill down around your body and reduces the amount of space your body needs to heat. WarmZip gives you the power to add up to 10F/6C to the Boost’s temperature rating. Standard Therm-a-Rest features like a puffy draft collar, a draft tube along the entry zipper line and a cinchable hood round out the Boost’s bliss-inducing comfort. The Boost 650 was built to backpack—we dialed in the materials and design to make it light, packable and high-performing in variable backcountry conditions. Zoned Insulation places the 650-fill hydrophobic down in key warmth-retention areas (on top, around your core and shoulders) and reduces it where it’s less efficient (on the bottom), allowing the Boost to create more warmth with less down. The shell and liner are made of 100%-recycled nylon that was handpicked for its light weight and super-soft feel. The PFAS-free DWR coating and the hydrophobic down keep the Boost warm and comfy even in wet weather.

  • Boost 650: Ultra-comfy three-season backpacking sleeping bag with adjustable shape and warmth
  • Customizable Comfort: Enjoy the spacious freedom of the semi-rectangular bag or the cozy warmth of a mummy bag
  • WarmZip™ Tech: Patent-pending center zipper design zips up to reduce the bag’s internal space and tuck insulation around the sleeper to boost warmth 
  • Multi-Use Arm Holes: Reach the WarmZip, read a book, play cards or simply ventilate — do it all while tucked into your sleeping bag for elevated livability
  • Plush & Puffy: 650-fill RDS-certified hydrophobic down is allocated to key areas with Zoned Insulation for refined heat efficiency and maximum coziness
  • Eco-Conscious Materials: Shell and liner are made of GRS-certified 100% recycled, soft-to-the-touch nylon and coated with PFAS-free water repellent

Beware of poor quality issues!
Color: Orange - 3.15Inch, Color: Orange - 3.15Inch
Got limited use out of ball, seemed to have quite a strong motor and was going to be a good buy. But upon going to recharge it for the first time, discovered the USB port was completely loose/not attached. Will steer clear of this brand going forward.

The Ball Never Gets Boring
Color: ‌Tangerine - 3.15Inch
My dog was immediately curious about this ball, and that curiosity turned into a surprisingly long play session. The movement keeps things unpredictable enough that it holds attention longer than a standard toy. I liked that it encouraged activity without requiring me to constantly throw something across the room. The textured surface also seemed easy for my dog to grab and carry around. One thing I noticed is that hard floors allow the ball to move around much more dramatically than carpet. It feels sturdy enough to handle enthusiastic play and occasional chewing. The bright color makes it easy to spot when it inevitably ends up under furniture. Charging was simple and didn’t become a hassle.

Tough build for rowdy play sessions
Color: ‌Tangerine - 3.15Inch
I picked up this motorized E-TPU dog ball last Thursday to keep my German Shepherd occupied during my afternoon video conferences in Folsom. The product quality is evident in the spongy, high-density foam construction, which provides a satisfying grip for his jaws without sustaining a single tear or puncture. The built-in motion sensor is highly responsive, sending the ball into an unpredictable frenzy of hops and spins whenever it gets nudged. It offers excellent value for money because the structural integrity holds up perfectly against aggressive chewing that would normally shred standard rubber toys in minutes. For a parent or professional needing a functional, autonomous distraction to burn off their pet's excess energy indoors, this rugged smart toy delivers a very reliable and quiet performance.

My dog really likes it
Color: ‌Tangerine - 3.15Inch
My golden retriever has a lot of energy, especially on rainy days when we can’t stay outside for long. This rolling ball has been a fun way to keep him entertained indoors. The movement is unpredictable enough to keep him interested, and he’ll follow it around the living room until he’s ready for a nap. The material has held up well to daily play, and it’s easy to recharge when needed. Watching him chase it around has honestly been entertaining for the whole family. Great toy for keeping active dogs busy. What I like most is that it gives him something to do without needing constant attention from us. The ball rolls on its own, changes direction, and keeps him engaged much longer than some of his other toys. A nice option for dogs that need extra stimulation during the day.

Keeps my puppy happy!!
Color: Orange - 3.15Inch
My 8 month old puppy loves this ball!! He is so happy when we charge it up for him!! It's great because it keeps him busy for a few minutes and it tires him out. This is our second one so we always have one ready to go for him.
