Wear a moisture-wicking base layer, fleece or grid mid-layer, and a packable wind shell with trail pants. The three-layer system handles temperature swings on trail. Four formulas plus trail-tested footwear and accessory picks for cool-day hikes.
Wear a long-sleeve or light layer in sun, add a cardigan or shirt-jacket for shade. Sixty degrees is single-layer in sun, two-layer in shade. Four formulas plus the shirt-jacket and cardigan picks for indoor-outdoor transitions.
Wear a light jacket or shirt-jacket over a long-sleeve with jeans or chinos. Fifty degrees is the pure layering zone - one layer too thin, two usually right. Four formulas plus the mid-layer pick that decides comfortable from cold.

Seasonal Guides
Wear a waterproof shell over a fleece or wool mid-layer with chinos and waterproof footwear. Sixty-degree rain sounds warm but drops effective temperature into the 40s. Four waterproof-plus-layer formulas plus the rain shell and mid-layer picks.
Occasion Wear
Wear a fitted sweater, slim jeans or dress pants, and dress boots, with a coat that does not bulk the silhouette. The outfit has to read well once the coat comes off. Three formulas for restaurants, bars, and outdoor events plus the slim layers that work under a coat.
Occasion Wear
Wear a breathable tee or light dress with shorts or light pants, plus a packable layer for after sunset. Temperature drops 10-15F once the sun goes down. Pavilion, lawn, and festival formulas plus the shoes that handle grass and hours of standing.

Wear a long-sleeve tech shirt with shorts or light tights - nothing else for most efforts. Fifty is the start-cool-and-warm-up zone where overdressing is the bigger risk. Pace-vs-effort formulas plus the chafe-resistant picks.
Activity Guides
Wear a long-sleeve tech base, light midlayer or vest, tights or split shorts, plus gloves and headwear. Hands and ears need protection at 40F more than your core does. Pace-vs-effort formulas plus the gloves, headwear, and shoe picks.
City Guides
Wear a wool coat or parka over a sweater and thermal base, with insulated boots and wool socks. December in NYC is genuinely cold - warmth is the foundation, not an afterthought. Layering formulas plus coat, boot, and accessory picks for subway-to-street transitions.
Seasonal Guides
Wear a hardshell or insulated rain jacket over a fleece, with waterproof boots and warm socks. Rain at 50F feels like 40F dry - real cold-rain gear is required. Four waterproof-plus-warm-layer formulas plus the hardshell, fleece, and boot picks.
Seasonal Guides
Wear a moisture-wicking tee or breathable linen with shorts or loose pants - and bring a change. Humidity above 70% at 80F stalls your body cooling system, so fabric choice is critical. Four moisture-management formulas plus wicking fabric picks.
