I love the Sassy 3l. This is the Sasquatch lines answer to the vintersars. And it slays. The Back Door-Tex is as waterproof as it gets. Paired up with a fantastic long cut, and another winning Airblaster design, this jacket gets high marks. I'm talking Colorado Mile High marks. I have worn this jacket on blower days, slush puddle days, and it never lets me down. Keep in mind, this is just a shell, you will want to pair it with some nice thermals or a ninja suit for added warmth on those chilly days on the hill. Recently wore it while hiking James Peak at Powder Mountain and it was perfect. Opened up the vents on the way up to dump heat. Zipped up at 9400 feet to withstand the breeze at the summit. Sinched up the powder skirt on the way down. Nothing but smiles all day!
