Every curve and millimeter of the CryoFlex 54 eliminates the weak points of disposable molded plastic sleds.
High-molecular-weight 1.1mm dark blue polymer flexes smoothly over frozen moguls instead of turning brittle and shattering like rigid tubs.
Coils into a neat 4.5" × 18" cylinder secured with its elastic strap—pack four sleds inside one tote bag with 85% of your trunk wide open.
Two smooth-beveled 4.2" oval handle cutouts let gloved hands curl the scalloped front nose upward at 35° to plane cleanly over snow.
91% lighter than a 10 lb plastic toboggan or steel runner sled, so kids happily carry their own sled right back up the hill all afternoon.
Rigid injection-molded tubs lock up and fracture on frozen boot ruts. Our solid 1.1mm cold-flex polymer bends a full 180 degrees in sub-zero air without stress-whitening or splitting.
Slip winter mittens through the two smooth front oval cutouts and pull gently back. The scalloped front edge arches into a 35-degree ski tip that rides atop snow instead of plowing.
With zero fold creases, zero rivets, and zero sunken side rails creating drag, the continuous semi-glossy dark blue underside delivers blistering downhill glide for kids and 230 lb adults alike.

Every snapped sled starts at a rivet hole, rope grommet, or brittle side rail. CryoFlex 54 is stamped from one solid cold-flex sheet with smooth-radius oval grips tested under 150 lbs of static load.
Foldable foam boards have permanent accordion creases that drag like speed brakes. Rolling into a smooth cylinder keeps our semi-glossy dark blue base unbroken from nose to tail.
Keep a family set permanently tucked in your spare-tire trunk well all winter so you never miss spontaneous fresh powder at the park.

Slip off the storage strap at the top of the hill, give the tail one quick reverse-flex, and place one snow boot onto the back edge to hold the mat flat on the snow.
Sit centered with your legs extended forward, slip gloved hands through both front oval cutouts, and pull slightly upward to arch the scalloped bow.
Lean smoothly to carve down packed snow, then roll the 0.85 lb mat right under one arm for an effortless walk back up the slope.
I'm 6'4" and 230 lbs, and this little mat has held up through two winters. It absolutely flies on packed snow. Honestly, once the hill gets steep, wear a helmet because it picks up serious speed.
Simply the best roll-up mat sled we've used. It's light, quick, easy to carry uphill, and ridiculously fun on packed snow.
Ordering was easy and it arrived quickly. My kids rode it pretty much all day, and the lightweight design meant they could carry it back uphill themselves. Definitely recommend it.
Bought this for the younger kids, but my older teenage boys ended up having a blast too. The smooth blue plastic flexed through some pretty rough rides and still looks great.
It's thin, but that's actually the advantage. The plastic flexes and rolls instead of turning brittle and shattering in freezing weather. Ours has handled repeated use and glides super fast over packed snow.
Great sled. My son and I take turns, and I've also tucked him in front of me for slower runs. We always shattered those rigid little disc sleds after a few trips, but this flexible mat keeps going.
Such a cute, sleek dark blue sled. The rolled design is simple, and the cutout handles have nice smooth edges. Really well made!
I ordered two so each of my teens could ride solo, and they went soaring down the hill. The front oval handles are perfectly placed for pulling the scalloped nose upward and hanging on. They love them!
After several days of riding, the dark blue bottom has a few little scratches from hidden twigs and gravel. That's expected on a sled. Nothing has split or affected the structure, and the flexible sheet still works perfectly.
We switched after the molded handles on our rigid saucer sleds kept snapping in the cold. These grips are oval holes cut directly into the flexible sheet, so they bend along with it instead of cracking off.

Yes. Unlike short kid-sized discs, the full 54-inch by 18-inch rectangular body supports solo riders up to 250 lbs. Our 6'4", 230 lb tester rode it across two winters of packed snow without tearing the oval handle cutouts or cracking the sheet.
Not at all. Each 4.2-inch wide oval grip handle is precision die-cut with smooth, burr-free rounded edges specifically sized to fit insulated adult winter gloves and thick kids' ski mittens comfortably.
No. The 1.1mm high-density cold-flex polymer stays pliable down to -30°F (-34°C). Instead of turning glass-brittle like rigid injection-molded plastic tubs, it flexes smoothly over frozen ruts and moguls.
No—by design, it is a pure single-layer 1.1mm roll-up racing polymer sheet with two integrated die-cut front oval handles and zero ropes or grommets that can snap or tangle. It rolls into a 0.85 lb cylinder you carry under one arm.
Simply slip off the elastic storage band, give the tail one quick 3-second gentle reverse-flex in your hands, step one snow boot onto the back edge to anchor it flat on the snow, sit down, and pull upward on the two front oval cutouts.
Take the CryoFlex 54 down your local hill for 30 days—normal surface scuffs from snow and twigs are expected, and if you aren't thrilled with the speed and space savings, return it for a full refund. Plus, if the polymer sheet or oval handles ever crack or split in freezing weather within 2 full years, we replace it free.
