Arc'teryx Arenite Jacket
The Arc'teryx Arenite Jacket (Model #16234) weighs approximately 410-430 grams in Men's M and uses Cobblecomb fleece for exceptional warmth in a technical midlayer. The 94% polyester and 6% elastane construction creates a durable twill face with a lofted fleece interior that effectively traps heat. The athletic fit stays close to the body while gusseted underarms and articulated patterning provide unrestricted mobility. This is one of Arc'teryx's warmest fleeces, and the fit works perfectly for my frame.
Cobblecomb Fleece Construction
Cobblecomb represents Arc'teryx's proprietary fleece construction that balances warmth with durability. The twill-textured outer face resists pilling and abrasion while allowing shell layers to slide on and off without friction. The brushed fleece interior traps warm air in its loft while wicking moisture away from the body.
The elastane content provides stretch that enhances mobility beyond what standard fleece delivers. The fabric moves with the body during climbing, skiing, and hiking without binding or restricting movement. After nearly a decade of use, my Arenite shows no pilling on the face fabric, confirming the durability claims.
How Does the Arc'teryx Arenite Jacket Fit?
The athletic fit stays relatively close to the body with room for a baselayer and light midlayer underneath. Articulation and anatomic patterning, combined with gusseted underarms, provide exceptional ergonomic performance. When layered under an Arc'teryx shell, the fit and articulation align to create a system that moves with the body.
The tall collar provides wind protection without the bulk of a hood, making this suitable for use under hooded shells. The zipper garage prevents chin irritation during extended wear. Low-profile cuffs fit easily under gloves without bunching.
Arc'teryx's Warmest Essentials Fleece
Arc'teryx designates this as the warmest fleece in their Essentials collection, and the lofted interior confirms this. The Cobblecomb construction traps more warmth than Polartec fleeces at similar weights. Temperatures between 20°F and 40°F work well as a standalone, while colder conditions benefit from shell layering.
The breathable construction prevents overheating during activity despite the substantial warmth. I've worn this during snowboarding warm-ups and chairlift rides without needing to unzip or take it off. The temperature regulation handles variable conditions better than cheaper fleeces that trap heat.
Smooth Twill Face Layers Without Catching
The smooth twill face slides under shell jackets without catching or bunching. The slim profile avoids the bulk that cheaper fleeces create when layered. The articulation aligns with Arc'teryx shell patterns, creating a cohesive system rather than fighting against the outer layer.
Two laminated hand pockets provide secure storage without bulk. The zippered construction keeps contents secure during activity, and the laminated finish adds water resistance at the opening.
Colorways and Design
Colorways include Phoenix, Azul, Sangria, Adriatic Blue, Anaconda, Odysseus, and Black across various seasons. The muted earth tones and subtle branding create a refined aesthetic that works in both outdoor and urban contexts. The embroidered logo provides brand identification without overwhelming the clean design.
Is the Arc'teryx Arenite Jacket Worth $180-220?
The price reflects Arc'teryx's premium positioning and the Cobblecomb fleece's performance. For those prioritizing warmth, durability, and mobility in a technical fleece, the Arenite delivers. The construction quality and material performance justify the cost over alternatives that compromise on one or more dimensions.
For casual use where maximum warmth isn't necessary, more affordable fleeces serve adequately. The Arenite targets serious outdoor use where performance under shells and in variable conditions matters. Check the Arc'teryx website for current availability and colorways.
