TETON Sports Evergreen sleeping bag, Night/Olive, 20F Regular — roomy flannel-lined adult camping bag for cold nights

The TETON Sports Evergreen Sleeping Bag is a roomy, flannel-lined all-season adult sleeping bag designed to deliver adaptable warmth and easy packing for cold nights or mild weather.

Built to bridge the gap between a snug mummy bag and a bulky blanket, the Evergreen gives campers a more relaxed fit without sacrificing warmth control or durability. Offered in multiple temperature ratings, its soft flannel interior and tough outer shell make it a practical pick for weekend car-camping, long campsite stays, or layering inside a tent on chilly evenings. The bag also zips together, lays flat like a blanket, and compresses quickly for transport.

How warm will this 20°F-rated Evergreen sleeping bag keep me?

The 20°F model is designed for cool to cold conditions where average adults need moderate insulation. It performs best when used with proper layering and a sleeping pad that insulates from cold ground; individual comfort will vary with clothing, metabolism, and weather.

• 20°F (approx.) rating suitable for cool nights and transitional seasons
• Flannel lining for added next-to-skin comfort and a warmer feel
• Use with a sleeping pad to prevent heat loss to the ground
• Available in multiple temperature options to match trip conditions

How does the Evergreen give a more spacious sleeping experience?

Instead of a tapered mummy cut, this bag uses a roomy rectangular shape that lets you move, stretch, and sleep in different positions. That extra interior space reduces the constriction some campers feel and makes the Evergreen easier to layer with blankets or clothing.

• Generous rectangular fit for side or back sleepers
• Room to add clothing layers without bunching insulation
• Compatible zipper design to pair two bags into a double
• Lays flat and doubles as a blanket at milder temperatures

What materials and features help it stand up to outdoor use?

The Evergreen combines a soft flannel lining with a durable outer shell to balance comfort and abrasion resistance. The construction is straightforward and focused on repeatable campsite use: a dependable zipper, reinforced seams, and built-in compression straps for packing.

• Soft flannel interior for comfort and a warmer tactile feel
• Durable exterior fabric that resists everyday campsite wear
• Sturdy zipper and seam work for long-term reliability
• Integrated compression straps make it compact for transport

How versatile is the Evergreen for different trip styles?

The design supports multiple ways to use the bag: zip two together for couples, lay it flat as an extra blanket, or compress and haul for car-camping and short hikes. Temperature rating choices and the ability to layer mean the same model can serve across seasons when paired appropriately.

• Zip-to-join feature lets two bags become a double sleeping system
• Flat-lay option turns the bag into a camp blanket at milder temps
• Compression straps and compact packing for easy transport
• Multiple temperature ratings let you pick the right model for your region

Who is this for: The TETON Sports Evergreen Sleeping Bag is aimed at campers who want more interior room than a mummy bag, a soft flannel feel, and a practical all-season option at a value price. It’s well suited to car campers, campsite families, casual backpackers who prioritize comfort over ultralight weight, and anyone who prefers a flexible sleeping system that can be zipped or layered for changing conditions.
