While there may be a linear relationship between increased tyre size and increased fun, this relationship only holds true when wider tyres are paired with the correct width rims. Having a three-inch tyre mated to a narrow rim makes for a squirmy, poor handling experience, and when youÕre on the hunt for additional fun, these characteristics are undesirable. Lucky for you, the new age of traction, stability, and speed has arrivedÑand its name is the Traverse 38 SL Fattie 650b with a 148 rear.

While our 30-millimeter Traverse SL is already wider than most offerings from others, the benefits of three-inch tyres become more apparent with a proper rim interface. In search for the proper width, our engineers tested various iterations, from 30 to 45 millimetres, to determine where the sweet spot lies. What they ended up with is a 38-millimeter internal rim width that turns the Traverse 38 SL Fatties into descending machines.

A wide internal rim width endows riders with a variety of advantages that are exemplified even more with plus-sized tyres. The extra width allows for more tyre volume, translating into more supple ride qualities, and better support for the tyre, meaning that you'll experience less "burping" when riding tubeless and a drastic increase in traction. After determining the proper rim width for the plus-sized application, we began designing the rim using the same low-weight, high-strength technologies used in the Traverse SL and the Control SL. With this, we started with our Zero Bead Hook design that effectively eliminates the biggest weak spot found in traditional rims, and topped it off by using high-modulus carbon fibre to keep the weight down to a respectable 1650 grams.

Each Traverse 38 SL Fattie is hand-built to our own alloy hubs with DT Swiss Revolution spokes. Inside our hubs, you'll find sealed cartridge bearings all-around, and a quick-engaging 54t DT Swiss star ratchet system in the rear, allowing you to power over rocks and roots without delay. And while machines do a decent job of building wheels, we choose professionally trained humans to build ours, as they catch various flaws that a machine would otherwise miss. You likely noticed that the 24-front/28-rear spoke count seems low for such a burly wheelset, but during testing we discovered that when built with 32 spokes, the wheels were too stiff, resulting in poor ride quality.

To further reduce the overall weight, the wheels also include the Roval tubeless plug system, which sheds an additional 50-grams-per-wheel compared to a rim strip. Finally, with the 110/148 variant, you receive all of the benefits that Boost spacing offers. By increasing the width of the front and rear hub flanges, and in turn, increasing frame and fork clearance and stiffness, you obtain a stiffer, stronger, and more durable system at a minor weight penalty.

If youÕre headed into the plus-sized wheel market, pick yourself up a set of Traverse Fattie SL 38 650Bs and notice for yourself that Fatties donÕt have to feel fat.

Bedsure Wearable Blanket Hoodie for Women – Galaxy Printed Shaggy Sherpa Cozy Hood
I bought this wearable blanket about a year ago as a gift for my wife, but it wasn’t quite her preference. However, my son ended up using it regularly during the winter, and he absolutely loves it. The material feels soft and cozy, the loose-fitting design is comfortable, and it’s easy to wear all day indoors when it’s cold. The galaxy print also adds a fun touch. I would highly recommend this product for middle school or high school–aged kids who want something warm and comfortable to wear inside the house. Considering the quality and price, it’s definitely worth buying. It’s a yes for me 👍

Size: One Size, Style: Shark, Color: Sky Blue
Super soft and comfy. Much bigger than I thought for a "one size" item. It comes down below my knees and is big enough to warm my feet if I'm all curled up. It's so warm and inviting. My cats also want to leave a positive review. They love curling up with me when I'm wearing it. They also love to make biscuits in it.

Blanket Hoodie is a Winter Warmth Go To.
Size: One Size, Style: Mushroom, Color: Olive Green
This is very large and comfy! I am so pleased. A lot of times "one size fits all" does not, but this blanket hoodie is really big and soft, the sleeves are long and bunch but the elastic cuffs are wide and will keep the long sleeves in check. In front are two deep large pockets (not the kangaroo pouch you might think). I will be ordering a couple more to leave in our camper. I highly recommend this blanket hoodie.

One of my favorite impulse buys
Size: One Size, Style: Mushroom, Color: Olive Green
I ADORE this sweater/hoodie/blankie thing! It’s so big and comfy, it’s like wearing a hug. The fleece is super soft, so I’m trying to avoid washing it for as long as possible so it can stay this soft forever. The only drawback is that it will shed on your clothing the first few times you wear it, so beware. The mushrooms are so cute.
