Insulating when damp, packable and compressible, and with a water repellent finish the ThermoBall™ Eco Jacket should be part of any hiker's kit - particularly with the fluctuating weather we have in European alpine environments. This slimline jacket stows in its own pocket and features a chest pocket, two hand pockets and elasticated cuffs and hem. To top it all off, both the fabric and the insulation are made entirely from recycled polyester, putting discarded plastic to good use.
