Ranked #2 in Best Backpacking Sleeping Bags

Exped Terra 15

4.2

$109.95as of Jul 1

The Exped Terra 15 Sleeping Bag offers a compelling balance of warmth, weight, and affordability for 3-season backpacking use. REI's Emily Pennington praised its 650-fill down insulation, soft fabric, and practical features like the draft collar and 3D footbox. The bag is designed for middle-of-the-road sleepers and comes in five sizes to accommodate different body types. While it's well-suited for summer and early fall camping, ultralight enthusiasts may find it slightly heavier than their ideal setup. It's best for weekend warriors and backpackers seeking a budget-friendly option without sacrificing comfort.

Strengths

— Soft recycled 20-denier ripstop polyester shell and liner with OEKO-TEX® STANDARD 100 certification
— Adjustable draft collar and hood help retain warmth and prevent heat loss
— 3D footbox design allows better blood flow and keeps toes warm during sleep

Watch-outs

— Stuff sack is described as bulky despite compression
— Unisex sizing may not fit those who run cold well

4.4

$579.99as of Jul 1

However, it's not recommended for users who sleep very cold or for extreme conditions. The bag is ideal for ultralight backpackers seeking a balance between weight and warmth.

How they stack up

Exped Terra 15

The Exped Terra 15 offers a good balance of affordability and comfort, outperforming the Kelty Cosmic Down 20 in warmth and fabric quality, though it's heavier than the Mountain Hardwear Phantom 30. Compared to the Western Mountaineering MegaLite, it's less expensive but lacks the ultralight design and spaciousness.

Mountain Hardwear Phantom 30

Unlike the REI Co-op Trailmade 25, which prioritizes value and sizing inclusivity, the Mountain Hardwear Phantom 30 focuses on exceptional warmth-to-weight ratio with its 850-fill down, making it superior for ultralight backpackers. While the Western Mountaineering MegaLite offers more spaciousness and lighter weight, the Phantom 30 provides a better balance of warmth and packability for moderate conditions.
