Women's Acker Rock 3-in-1 Jacket

The Columbia Women's Acker Rock™ 3-in-1 Jacket is a versatile urban lifestyle jacket from Columbia's Heritage Collection, giving you three ways to wear in one piece. The cotton and stretch twill outer shell has a clean, everyday look; the 250g polyester fleece inner zips in via Columbia's Interchange System for added warmth; and both layers can be worn independently — adapting to everything from crisp mornings to warmer afternoons without needing to carry additional layers.

• Columbia Interchange System — the fleece inner layer zips into the outer shell via a compatible zip-in system, creating three distinct wear options: outer shell alone, fleece liner alone, or both combined for maximum warmth.
• Cotton and stretch twill outer shell — a 100% cotton and 98% cotton/2% elastane woven stretch twill construction gives the jacket a clean, heritage-inspired look with enough stretch for comfortable all-day movement; not waterproof but wind-resistant for mild urban conditions.
• 250g MTR filament polyester fleece inner — a mid-weight fleece liner that provides meaningful warmth when worn zipped into the shell, and works as a standalone cosy layer in mild weather.
• Adjustable waist tabs and sleeve cuffs — waist tabs allow the fit to be cinched for a more tailored silhouette; cuff adjustments personalise the sleeve fit and help seal out draughts at the wrist.
• Center front button closure — a clean button front on the outer shell in keeping with the heritage aesthetic of the collection.
• Practical pocket configuration — chest pockets and drop-in hand pockets provide storage for daily essentials without breaking the clean line of the jacket.
• Heritage Collection — part of Columbia's Heritage Collection, inspired by Oregon's natural landscape; refreshed retro styling with built-in everyday utility.
