Sea to Summit Trek Down Sleeping Bag

The tapered-rectangular shape offers significantly more room in the shoulders, hips, and footbox compared to a mummy bag. It is designed for sleepers who find mummy bags too restrictive and prefer the freedom to move their legs or sleep in various positions.

Yes. The Free-Flow Zip System allows you to unzip the bag completely, letting it lay flat like a quilt. This makes it highly versatile for warmer nights or for use in a van or camper where you might want a traditional blanket feel.

The bag uses Ultra-Dry Down, which is treated to resist moisture and maintain loft in damp conditions. While it is water-resistant, it is still a down product and should be kept dry whenever possible to ensure maximum warmth and longevity.

With a 30-degree Fahrenheit temperature rating, this bag is ideal for cool-to-warm camping conditions. It is well-suited for spring, summer, and early autumn trips, though your personal warmth preference and sleeping pad insulation will also play a role in your comfort.

It packs down to a volume of 8.2 liters, making it relatively compact for a bag of this size and warmth. It is well-suited for overlanding or car camping where space is managed but not as critical as it would be for ultralight backpacking.
