Runs true to size. If you're between sizes, order up.
When temperatures drop and winds gust, our S4 Tower Parka will keep you warm while working at heights—without sacrificing breathability. Strategically placed insulation (heavier in the torso area and lighter in the sleeves) means uncompromised mobility. Additionally, the fabric is completely windproof and waterproof. And a clever zippered opening on the back allows for the passage of a safety harness D-ring for working at height.

Field Diary

“Great jacket! Super warm, very easy to move in. I spent 10 hours in -15 degree temps in this jacket last week with no issues. Side zips work great for cross ventilation as well as accessing tools and equipment that you keep in the chest pockets of your bibs. I’ve been wearing this jacket since the early part of November. I’m a fire investigator and normally go through 1 cheap hi-viz jacket a winter. So far this jacket is holding up really well. Very durable and no rips yet!”
