Members Only Packable Windbreaker vs Montane Fortes Lite Hooded Insulated Jacket

Buy the Members Only windbreaker if you want a shell that blocks wind, sheds light rain and stuffs into its own pocket for summer evenings, travel or air-conditioned rooms. Buy the Montane Fortes Lite if you need actual warmth from a jacket that still breathes during hard activity. The windbreaker is a single-layer nylon shell with no insulation; the Montane adds PrimaLoft Gold Active Vent, 60g in the body and 40g in the arms, at 335 g. Owners of the windbreaker rate it 4.7 from 51 ratings and praise the fit, packability and water resistance, but several say it runs small, so size up.

• Choose the Members Only Packable Windbreaker if you want a light, hooded shell that folds to envelope size for wind, drizzle and cool evenings.
• Choose the Montane Fortes Lite if you want a breathable insulated layer for cold-weather hiking, climbing or running.
