{"product_id":"arcteryx-atom-vest-mongoose","title":"Arc'teryx Atom Vest Men's Mongoose","description":"\u003cp\u003eThe Arc'teryx Atom Vest Men's in Mongoose adds \u003cstrong\u003elightweight core warmth\u003c\/strong\u003e while leaving your arms free for walking, climbing and everyday movement. Its sleeveless construction makes sense when a full insulated jacket feels excessive, or when you want a compact layer beneath a waterproof shell. This is \u003cstrong\u003esynthetic insulation for active use\u003c\/strong\u003e, with a close, uncomplicated shape.\u003c\/p\u003e\u003cp\u003eThe shell uses \u003cstrong\u003eFortius Air 20\u003c\/strong\u003e, a woven fabric containing 88% nylon and 12% elastane. That stretch helps the vest move with you when reaching overhead or adjusting a backpack. The lining shares the same nylon and elastane proportions. Rather than relying on a stiff outer fabric, the construction balances a light feel with the flexibility needed for repeated movement.\u003c\/p\u003e\u003cp\u003eInside, \u003cstrong\u003e40 g\/m² Coreloft Stretch insulation\u003c\/strong\u003e provides warmth through the body. The polyester insulation continues to offer warmth when damp, which is useful during changeable outings. \u003cstrong\u003eOcta fleece side panels\u003c\/strong\u003e add stretch and ventilation where heat can build up. Those panels are 100% polyester; they serve a different purpose from the insulated main body and help explain the vest's active layering role.\u003c\/p\u003e\u003cp\u003eArc'teryx describes the cut as \u003cstrong\u003eFitted\u003c\/strong\u003e. It stays close through the torso, allowing the vest to sit under an outer jacket without unnecessary bunching. Try it over the base layer or lightweight fleece you intend to wear, and check that the front zip closes comfortably without pulling across your chest. A closer fit should still leave room for normal breathing and shoulder movement.\u003c\/p\u003e\u003cp\u003eTwo \u003cstrong\u003econcealed zippered hand pockets\u003c\/strong\u003e keep small essentials accessible, while an adjustable hem drawcord helps reduce draughts around your waist. The \u003cstrong\u003eFC0 DWR finish\u003c\/strong\u003e encourages light moisture to bead on the surface. It is a surface treatment, rather than a waterproof membrane: carry a shell when sustained rain is likely. The sleeveless design also leaves your arms dependent on your other layers.\u003c\/p\u003e\u003cp\u003eFor care, follow the sewn-in label: Arc'teryx specifies a \u003cstrong\u003egentle cool wash and gentle low tumble drying\u003c\/strong\u003e, without fabric softener, bleach or ironing. Rinse twice and avoid wringing. Choose this vest when you want adaptable warmth across changing activity levels, rather than a heavily insulated standalone winter layer.
