The Dynafit Alpine Running Vest in Black Out with Fluo Yellow is a 76 gram wind vest with a high visibility yellow accent. It is a garment rather than a hydration pack: a light windproof body with a full zip, worn to cut wind chill on exposed ground while the arms stay bare.

• Black Out with Fluo Yellow: the fluorescent panel is the visibility option in the range, which matters on roads and shared trails at dusk.
• 76 g: it compresses to nothing and lives in a vest pocket.
• Not a pack: there is no cargo volume and no soft flasks are included, only pockets.
• Pockets: one zipped, one for a gel or flask, one for a phone.
• Semi autolock zip: opens fully to dump heat on a climb and stays shut on the way down.
• Polygiene lining: Polygiene treated mesh lining, plus a reflective snow leopard head.
• Sizing: Unisex, S to L.
• Full Zip
• Zip Pocket
• Gel/Flask Pocket
