Sea to Summit Ember 35°F Ultralight Down Quilt – Long Size

Sea to Summit Ember 35°F Ultralight Down Quilt

The Ember 35-Degree Ultralight Down Quilt is designed for bike packers, backpackers, hikers, and travelers who want lightweight insulation without the bulk of a traditional bag. It balances warmth, compressibility, and ease of use so you can focus on your route and the night sky. With a long size option that accommodates up to 6'6", this quilt aims to keep you comfortable on two-season adventures while packing down neatly into a compact sack.

Soft, high-loft down and thoughtfully chosen fabrics work together to deliver reliable warmth without restricting movement. The result is a versatile sleeping companion that can adapt to a wide range of conditions and setups, from bivouac to hostel floors, or a base in a remote campsite.

Key materials and warmth

• 850 fill power down insulation (RDS certified) treated with ULTRA-DRY Down to help loft rebound when exposed to moisture.
• Ultralight 10D nylon shell paired with a 7D nylon lining reduces weight and bulk while maintaining durability.

Construction and warmth distribution

• Box-baffle construction stabilizes the insulation for even warmth along the quilt.
• Heat stays inside as you move, thanks to a design that minimizes dead zones and maximizes loft.

Attachment, versatility, and packability

• Snap-on attachment straps secure the quilt to a sleeping pad, keeping it in place as you change positions.
• Base drawcord creates a snug foot pocket; press-studs can join two Embers for an oversized quilt.
• Regular fits up to ~6 feet tall; Long size supports up to 6'6" for taller users.
• Includes Ultra-Sil compression sack; packs down to about 4.9 liters for easy carry.

Sea to Summit backs this quilt with a lifetime guarantee against defects in materials or workmanship, underscoring its role as a trusted companion for travelers who value lightweight gear that performs when it matters.

Whether you’re cycling a remote route, hiking variable weather, or traveling with minimal luggage, the Ember offers a practical balance of warmth, weight, and adaptability. Keep in mind that warmth can vary with climate, clothing, and pad setup; treat this quilt as a possibility for comfort rather than a guaranteed outcome in extreme conditions.
