MarmotIsotherm Insulated Hooded Jacket - Women's

Put the berries down.

As nice as it might sound, hibernating through winter isn't really an option—you haven't eaten near enough salmon and rose hips to make it through the winter. Lucky for you, the Marmot Women's Isotherm Insulated Hooded Jacket offers warmth you don't have to forage for thanks to its synthetic insulation. A great insulating jacket for when you're on the move, the Isotherm is insulated with Polartec Alpha insulation, which is breathable, quick to dry, and it will maintain insulating properties if it happens to get wet. For added protection against the elements, the jacket is fitted with a stretch softshell material throughout the shoulders and sleeves, while its elastic bound cuffs and hood help lock in heat whether you're on belay, warming up at the top of the skintrack, or hunkering down in your cave for another long nap.

I want it to be cold so I can wear this jacket everyday! Its light weight construction makes it easy to layer under or over and it’s SO WARM without being bulky. This is jacket is versatile and easy to pack. It’s a no brainer for any outdoor adventure.

Pretty stoked on this piece. I have to agree with the below, good for just about everything. It's been a valuable addition to the wardrobe, works for layering in the winter, summer camping. Side panels are a breathable, knit stretch, outter fabric is coated with a DWR, slightly water repellent and the synthetic insulation is warm without the bulk. There's a thin , soft interior fabric that feels great but got a little mangled in the washing machine. REMEMBER to zip this guy up before washing. I have a medium, fits great, can fit a few thing layers underneath, and it's long in the sleeves and torso.

Everyday and Activity!

I Love love this jacket- not only is it stylish enough to wear as an everyday jacket it also performs as a technical jacket. I'm never too hot due to it's breathability and the fabric allows the jacket to move with me, I never feel restricted (even while snowboarding using it as an extra layer on cold days under my shell). I get compliments on this jacket all the time- highly suggest you get one! (i like mine a little bigger so I went with MD)
