The Barfly Microshell Jacket is our lightest waterproof layer at 480 grams (17.25oz). Streamlined for packability, we prioritize simplicity and weather protection to deliver a highly packable, high-performance 3-layer 30k / 30K waterproof / breathable shell that's easy to find room for.

Updates for 2025 include adding a double storm flap over the center front zipper, replacing the chest pocket with two hand pockets, and incorporating four-way abrasion-resistant stretch nylon fabric in high-wear areas on the arms to improve durability.

Combine with the matching Barfly Overpant and insulated Jackaloft or Ectotherm Jacket to create a versatile multi-season layering system that packs down small.
