Perfect for the UK, any warmth you generate is retained in this Thermoball jacket.
For a warm, do it all insulation layer, choose a Thermoball Hoodie from The North Face. Using Primaloft Thermoball insulation, body mapped to key areas to trap heat and also create great breathability, this jacket is not only light to wear but will keep you warm even if you get caught out and get a soaking. It compresses just like down and stows into its own pocket for storage. This jacket has an adjustable hood, zipped pockets and front and departure TNF logo.
We think The North Face Thermoball Hoodie makes a fantastic walking and hiking jacket that works extremely well in cold, windy conditions as well as those grey, drizzly days keeping you dry even when you think you are getting soaked through. This versatile, insulating layer is popular with climbers as it feels light even with the thickness of the 15 denier nylon outer giving it a tougher exterior and has a cinch hem drawcord which keeps out the way of climbing harnesses or the waist belt of a rucksack.
This microlight insulated hiking jacket compresses down into its own pocket which is a great space saver especially when you have a decent amount of other gear to carry and we have found that it is sized big so worth considering what you might wear underneath before ordering.
