Arc'teryx Delta AR Zip

If you’re looking for warmth, comfort and durability in a mid-layer, the Delta AR Zip is an ideal choice. I’ve compared this layer to Mountain Hardwear’s Micro Chill Zip-T and The North Face’s Micro TKA and found that while these garments do perform well, the Delta AR is warmer and more comfortable, primarily due to its functional design features and fabric material. Its long length keeps out the elements, and it’s soft, comfortable high-loft grid fabric traps heat and wick’s moisture very efficiently. Also, a long front zip quickly vents heat and helps regulate body temperature.

When combined with a lined soft shell (i.e. Venta SV Jacket), or GTX hard shell, my ascents of peaks in NYS’s Adirondack and Catskill Mountains are warm and comfortable, even in temperature ranges as low as -10 to 10 degrees. I’m always amazed at its insulating properties. It also packs light and even looks great with jeans. Care is simple; a warm wash followed by a low heat dry cycle gets it clean.

I received my first Delta AR as a gift this past Christmas, but after using it so often peak-bagging and around town, I purchased another to make sure I always have one available to keep me warm and comfortable this cold Winter season.
