I took the Super Mica backpacking on Camel's Hump as a windshirt, and as an outer layer during high-intensity hiking. While in my sleeping bag- NOT while hiking- a long piece of seam tape detached from the inner lining all at once. I put it in my pack, planning to use it as evidence to return it.
The next night, while I was very gently (trust me) wiggling out of the jacket in my sleeping bag, the entire back seam from shoulderblade to shoulderblade tore like paper. This was a different seam from the tape incident, and it was right along the seam the entire way.
I've been babying this jacket, never washed it, used only a handful of times. Think, there's only been three rainstorms since August where I've been outside a lot, so less than 10 uses. It really disintegrated.
Replaced by Zappos, no questions asked, with a Patagonia Super Cell jacket, which looks to be higher quality. And honestly, I prefer a bright blue for biking to a black jacket anyways... so it's all for the best. I have not used any other Marmot products, but this definitely steers me away from lightweight gear from them. I wouldn't mind a fleece, those look high-quality, but this jacket was just flimsy.
Weight gain: 5 ounces. This experience puts durability back at a premium for me, given how much I rely on a good shell.
