Marmot Mad River 30 Sleeping Bag: 30 Degree Down

Mad River 30 delivers lightweight warmth, water-resistant down, and packability for three-season adventures

What Our Gearhead® Experts Are Saying:

"The Mad River 30 is my go-to bag for spring, summer, and fall backpacking trips. The 650-fill ExpeDRY down is warm, lightweight, and dries quickly if conditions get damp. The dual-zipper design lets me vent when I need to, and the draft collar keeps heat in when temperatures drop. Plus, the recycled materials make it a great eco-friendly choice. It’s the perfect balance of warmth, weight, and packability for milder nights on the trail."

We love the versatility of the Marmot Mad River 30 Sleeping Bag—light enough for warm-weather backpacking yet insulated enough to keep us cozy on crisp nights. Packed with 650-fill-power ExpeDRY down, this mummy bag offers the perfect blend of warmth and breathability, while the water-resistant treatment ensures it stays lofty and insulating even in damp conditions. With a lightweight, recycled nylon shell and lining, it’s a sustainable choice for eco-conscious adventurers.

Designed for comfort and efficiency on the trail, the Mad River 30 features a full-length, snag-free zipper for easy entry and exit, plus a secondary zipper for ventilation when temperatures rise. The draft collar helps lock in heat, and the anatomically wrapped footbox gives our feet extra warmth and space to move. Whether we’re camping under the stars in the summer or trekking through mild fall and spring nights, this bag delivers lightweight warmth for every adventure.
