Marmot Trestles Elite Eco 15

Best Backpacking Sleeping Bags

“The lighter, current-production successor to the standard Trestles 15 — and the budget-synthetic pick for this list. HL-ElixR Eco Micro insulation (100% recycled) rated to 15°F drops the regular to ~2 lb 12.5 oz, roughly 13 oz off the old Trestles, with a 3D footbox and included compression sack. Synthetic means it keeps loft when damp; it is still heavier and bulkier than down, so gram-counters on dry trips should look at the down bags above.”

The Brief

A Hooded Mummy, a Quilt, or a Wet-Weather Synthetic?

A fill-power hangtag is the wrong first question. Hooded mummy, quilt, or wet-weather synthetic is the bag. Then shop Gavler's live community ranking.
