The Forte is NEMO's synthetic-fill sleeping bag, with the 20°F Regular Wide variant rated for shoulder-season use. Synthetic insulation handles damp conditions better than down (no loft loss when wet), at the cost of slightly higher pack weight. Spoon shape allows side-sleeping. Recyclable shell and fill under NEMO's Endless Promise program. $229.95 at Backcountry.
