Built light and packable, for quick deployment when weather rolls in, this jacket provides fantastic wind protection, and some backup insurance if that wind is followed with rain. Think of it as an ideal backup plan when you're only pretty sure that today's a nice day to ride.Sportful built the Hot Pack 5 out of Schoeller's excellent Nanosphere fabric a lightweight, windproof layer that's DWR treated, and highly water resistant. In addition to being protective when weather rolls in, it's supremely light, making this jacket easy to pack in your jersey pocket. That task is made easier by an internal stuff sack. Sportful minimized the seams at the front of the jacket, reducing the number of points of entry for water, should you decide to test the limits of its waterproofness.The dual use cuffs offer thumb loops, to keep your wrists warm and protected from strong gusts. A drop tail keeps your backside covered in the event that road spray starts kicking up. A mesh panel at the back helps to evacuate excess heat when you're working hard. And reflective accents make you more visible to drivers, so you stay safer on the roads, especially if dusk sets in earlier than expected. The Sportful Hot Pack 5 Men's Jacket is available in seven sizes, from X Small, to 3X Large, and in the colors Black, White, and Yellow Fluo.
