Expert Insights
The Kelvin Aerolite Jacket is a "Cadillac" product offered by SITKA Gear concerning a synthetic insulation layer. The PrimaLoft Gold insulation with Cross Core technology permits a significantly warmer layering piece without the added bulk, ultimately enabling an outer shell to be worn over it with ease, such as a soft shell jacket or rain wear. This product is extremely versatile and packable, and should strongly be considered by any gear enthusiast or outdoor adventurer.
