Endeavor Field Insulator Jacket 2020 Review by The Good Ride

The Endeavor Field Insulator Jacket is an extremely warm mid-layer (I also tested this as an outer layer, under bibs)  that is constructed of some very unique materials. The shell is constructed from Dupont Tyvek and the insulation is duck down. This shell material is not very breathable, however, It seems windproof and very durable. At $125 this is a great value for an exceptionally warm mid-layer.
