The ThermaGrid Hooded Midlayer is built from a proprietary ThermaGrid grid fleece fabric engineered for high-output warmth. It’s extremely lightweight, highly breathable, and quick to dry, so you can run, skin, or ride hard without feeling weighed down or trapped in your own heat. Instead of stacking multiple tight layers, one ThermaGrid gives you a warm, cozy interior with the performance to keep you comfortable across varying effort levels and conditions.
Designed as a versatile midlayer for running, skiing, and riding, the ThermaGrid Hooded Midlayer sits at the intersection of technical and quiet. It’s advanced enough for serious days in the mountains, light enough for tempo runs, and comfortable enough that you forget you’re wearing something engineered at all, just you and whatever is right in front of you.

ThermaGrid fleece fabric is engineered for serious performance. Warm yet extremely lightweight, highly breathable, and fast-drying under high output. It moves moisture away from the body, traps just the right amount of heat, and reduces layer clutter so you can ride, run, and move through winter in a calm, regulated microclimate.
The minimalist hood adds quiet, contained warmth; easy under a helmet, shell, or beanie.
A front kangaroo pocket offers a safe space for hands or quick warm-ups, while the zippered Napoleon pocket secures small essentials (card, key, gel, or phone) close to the body and out of the way while you move.
Thumb loops help lock sleeves in place under outer layers and add extra coverage when it’s cold, turning the cuff into a simple, integrated hand-warmer.
Cold out? Doesn't matter. Throw this on and get outside. I love the thumb straps that keep the sleeves over my hands so I don't have to wear gloves. My hands inevitably get hot and sweaty and it's easier to pop em out of the straps than shoving gloves in pockets while running.

NorCal Fog Winter Go
Absolutely impressed, period. For the weight to warmth feature, I was amazed. I stand 5'4", I ordered Size Small, love it. It has been blister cold this year going into mid-Winter in NorCal. The fog this year has been bonkers, but the Thermagrid has done the trick to keep me going on my rides and my runs. The Hood feature is an engineered spectacular by these guys at O&S. Chilly starts on my ride, this hood feature easily tucks under the helmet, best part, cold straps and chin straps are also blocked off skin as the hood is covers snugly over ear and up to chin, yet stretchy and covers the neck. Once I have warmed up, hood pulls back and comfortably rests away from the wind resistance. Great product for anyone looking for amazing warm to weight ratio, on their next long cycling ride while being able to roll into the coffee shop without looking all goonie, stroll around in confidence and steeze for sure.

Perfect weight
Great light fleece for cold mornings that didn't get too warm once it warmed during socal winter rides. Would also work well as a snowboarding mid layer.

Awesome
Wearing this hoodie now on cold rides in NY. I layer it with a long sleeve underneath and this does the trick. Awesome layer.
