Evergreen XXL 20°F Sleeping Bag Review: Is It Worth It?

When you're shopping for a sleeping bag, the specs on the tag only tell part of the story. The Evergreen XXL 20°F sleeping bag from TETON Sports promises roomy comfort and reliable warmth for cold-weather campers. But does it deliver? We spent several nights testing it in a variety of conditions to find out.

In this review, we'll break down the Evergreen XXL's design, warmth, comfort, and overall value. Whether you're a tall camper who's tired of cramped bags or a side sleeper who wants extra room to move, we'll help you decide if this is the right sleeping bag for your next adventure.

First Impressions and Build Quality

The Evergreen XXL 20°F arrived well-packed and compressed into its included stuff sack. The outer shell is a soft-touch polyester that feels durable without being stiff or crinkly. The lining is a brushed cotton-poly blend that immediately feels cozy against the skin—no slippery or sweaty sensation. Stitching looks consistent, and the zippers glide smoothly without catching, which is a good sign for long-term durability.

One of the first things you notice is the sheer size. The Evergreen XXL is designed to give you extra space, and it doesn't disappoint. With a shoulder girth of 64 inches and a hip girth of 58 inches, it's noticeably wider than standard bags. This makes it a great option for broad-shouldered campers, side sleepers, or anyone who simply dislikes feeling confined.

• Shell: 190T polyester with water-resistant coating
• Lining: Soft brushed cotton-polyester blend
• Insulation: Polyester hollow fiber fill
• Zipper: Anti-snag, two-way with draft tube

Warmth and Temperature Rating

The Evergreen XXL is rated for 20°F, which makes it a solid three-season bag for most campers. In our tests, we found that the rating is accurate for average sleepers when paired with a good sleeping pad and appropriate base layers. We tested it down to about 25°F and stayed comfortably warm, though we did feel a slight chill at the shoulders if we rolled over and exposed the zipper area.

The key to the warmth is the combination of the insulating fill and the bag's roominess. The hollow-fiber polyester fill traps air effectively, and the extra space allows you to wear thicker layers or add a liner without feeling compressed. However, if you're a cold sleeper or plan to camp in temperatures below 20°F, you might want to consider a bag rated for lower temperatures, such as the Celsius XXL -25°F, which offers more aggressive insulation.

• Temperature rating: 20°F (comfort) / 0°F (limit)
• Insulation: 2 lbs of hollow-fiber polyester
• Draft tube along zipper to prevent heat loss
• Adjustable hood with drawcord for extra warmth

Comfort and Space for Tall Campers

If you're over 6 feet tall, you know the struggle of finding a sleeping bag that actually fits. The Evergreen XXL is 87 inches long, which provides ample room for most tall campers. At 6'2", I had extra space at the footbox and could stretch out fully without feeling the end of the bag. The extra girth also means you can move around and change positions without fighting the fabric.

The bag also features a generous footbox that allows your feet to move naturally and prevents the insulation from being compressed. For side sleepers, the roomy design is a game-changer—you can bend your knees without the bag twisting around you. The hood is well-designed, with a drawcord that cinches down around your face to keep warmth in, but it's not so tight that it feels restrictive.

• Length: 87 inches (fits up to 6'6")
• Shoulder girth: 64 inches
• Foot girth: 58 inches
• Hood with adjustable drawcord

Packability and Weight

Given its size and insulation, the Evergreen XXL is not a backpacking bag. It weighs about 6.5 pounds and compresses to a large stuff sack that measures roughly 20 inches by 12 inches when packed. This is fine for car camping, base camping, or any situation where you don't have to carry it far. If you're planning a backpacking trip, you'd want a lighter, more compressible option like the Talus 2700 Backpack, which is designed for ultralight adventures.

That said, the included compression sack does a decent job of reducing the bulk. The bag fits easily into a large duffel or the trunk of a car. For its intended use—comfortable car camping and cabin trips—the weight is not a dealbreaker, but it's worth noting if you have limited storage space.

• Weight: 6.5 lbs
• Compressed size: 20" x 12"
• Stuff sack included with compression straps
• Best for car camping, not backpacking

Versatility and Additional Features

The Evergreen XXL is designed to be a versatile bag that works in a variety of conditions. The two-way zipper allows you to vent your feet if you get too warm, and the full-length draft tube prevents cold air from seeping in through the zipper. The bag also unzips completely to form a large blanket, which is perfect for warm-weather camping or for sharing with a partner (though you'd need two bags to zip together).

For couples, the Evergreen XXL can be paired with another TETON Sports bag to create a double-wide sleeping system. However, if you're exclusively looking for a double bag, you might consider the Mammoth Double 20°F, which is designed specifically for two sleepers and offers even more room. The Evergreen XXL is best as a single-person bag with extra space.

• Two-way zipper for temperature control
• Unzips fully to use as a blanket
• Can zip with another Evergreen bag to make a double
• Interior pocket for small items

Value for Money and Comparisons

At its price point, the Evergreen XXL 20°F offers excellent value. It's not the cheapest bag on the market, but the quality of materials, the roomy design, and the reliable warmth make it a worthwhile investment for campers who prioritize comfort. Compared to other oversized bags, it holds its own in terms of construction and features.

If you're a cold sleeper or plan to camp in extreme conditions, you might want to look at the Celsius XXL -25°F, which offers more insulation for harsher winters. On the other hand, if you're on a budget and don't need the extra warmth, the standard Celsius XXL 20°F is a more affordable alternative. But for most campers, the Evergreen XXL hits the sweet spot between comfort, warmth, and price.

• Competitive price for the size and features
• Backed by TETON Sports' customer service
• Comes with a stuff sack and storage bag
• Available in multiple colors

The Evergreen XXL 20°F sleeping bag is a solid choice for campers who value space and comfort without sacrificing warmth. Its roomy design is perfect for tall or broad-shouldered individuals, and the 20°F rating handles most three-season conditions. While it's not a backpacking bag, it excels at car camping and basecamp use. If you're in the market for a comfortable, oversized sleeping bag, the Evergreen XXL is definitely worth considering. For those who need even more insulation for extreme cold, the Celsius XXL -25°F is a great alternative. Check out the Evergreen XXL 20°F on TETON Sports' website to see if it fits your camping style.
