Gander Mountain Sleeping Bags | Premium Outdoor Sleep Systems
Our Summit Ridge sleeping bag delivers reliable warmth down to 20°F with polyester synthetic fill that maintains insulation even in damp conditions. The mummy-style hood cinches tight to trap heat around your head and neck, while the full-length draft tube prevents cold air from sneaking through the zipper. We built this bag for three-season campers who need dependable performance without the premium price of down.
The 75D polyester shell sheds light moisture and holds up to trail wear, making it a practical choice for frequent weekend trips. At 3.2 pounds, it packs down to 8 x 16 inches in the included compression sack.
- 20°F comfort rating for spring through fall camping
- Synthetic polyester fill — maintains warmth when wet
- Mummy hood with drawcord for heat retention
- Two-way zipper with full-length draft tube
- Fits users up to 6’2″ tall
Temperature Ratings & Insulation Types
Every Gander Mountain sleeping bag carries an EN-tested temperature rating that tells you the lowest temperature at which an average sleeper will stay comfortable. Our 20°F and 30°F bags use synthetic polyester fill that continues insulating even when damp — critical for humid climates and unpredictable weather. Synthetic bags dry faster than down and cost less, making them the go-to choice for families and casual campers.
For cold-weather expeditions, our 0°F Alpine Pro uses 650-fill-power duck down that delivers superior warmth-to-weight ratio. Down compresses smaller and lasts longer than synthetic alternatives, but it requires dry conditions or a DWR-treated shell to maintain loft. We recommend synthetic bags for wet environments and down for alpine trips where pack weight matters most.
Sizing & Fit Guidelines
Proper fit ensures your sleeping bag performs to its rated temperature. Our adult bags accommodate sleepers up to 6’2″ in the Summit Ridge and Alpine Pro, while the Trailblazer fits heights up to 6′. Taller campers should consider adding six inches to their height when selecting a bag to avoid compressing insulation at the footbox.
The Kids’ Explorer measures 66 inches long — ideal for children between 4’6″ and 5’2″. A properly sized kids’ bag eliminates the excess fabric found in adult bags that creates cold spots around smaller bodies. If your child is approaching 5’6″, transition them to an adult model for better temperature performance.
Care & Storage Instructions
We build our synthetic sleeping bags to withstand machine washing in cold water on a gentle cycle. Use a front-loading washer to avoid agitator damage, and add a synthetic-safe detergent without fabric softeners that can coat fibers and reduce loft. Tumble dry on low heat with tennis balls to break up clumps and restore full insulation.
Down bags require more careful handling. Spot-clean minor stains with a damp cloth, and only machine wash when necessary using down-specific soap. Drying takes longer — plan for 2-3 cycles on low heat, checking frequently to redistribute down by hand. Overdrying damages natural oils that keep down supple.

Sleeping Bag Questions from Campers
For summer camping in most regions, a 30°F to 40°F rated bag handles typical overnight lows comfortably. Our Trailblazer 30°F works well for June through August trips, while the Kids’ Explorer 40°F is ideal for children during warm-weather months. If you camp in higher elevations or expect temperatures below 35°F, step up to the Summit Ridge 20°F for added security.
Remember that temperature ratings assume you’re sleeping in base layers on an insulated pad. Cold sleepers should choose a bag rated 10°F lower than expected nighttime temperatures.
Synthetic insulation in our Summit Ridge and Trailblazer bags performs better in wet conditions and costs less, making it ideal for humid climates, family camping, and budget-conscious buyers. Synthetic bags dry quickly and maintain warmth even when damp.
Down insulation in the Alpine Pro offers superior warmth-to-weight ratio and compresses smaller, perfect for backpacking and cold-weather expeditions where pack space matters. Down lasts longer but requires dry conditions or a DWR-treated shell. Choose synthetic for versatility and value, down for lightweight performance and extreme cold.
Stuff your sleeping bag loosely into its compression sack starting with the footbox — never roll it. Rolling creates permanent creases that damage insulation over time. Push the bag in randomly, allowing air to escape gradually through the opening.
Once the bag is inside, cinch the compression straps evenly in a star pattern to avoid creating stress points. For daily use on multi-day trips, don’t compress fully until you’re ready to pack up camp. This preserves loft and extends the bag’s lifespan.
Our synthetic sleeping bags are machine washable in front-loading washers using cold water on gentle cycle. Use a mild detergent without fabric softeners, and run an extra rinse cycle to remove all soap residue. Tumble dry on low heat with clean tennis balls to break up clumps and restore loft.
The Alpine Pro down bag requires down-specific detergent and more careful handling. Wash only when necessary, and expect 2-3 drying cycles on low heat. Never use top-loading washers with agitators, as they can tear baffles and redistribute insulation unevenly.
Our standard adult bags fit sleepers up to 6’2″, which may feel tight if you’re 6’3″ or taller. We recommend adding six inches to your height when selecting a bag to ensure the footbox doesn’t compress insulation. Compressed insulation at your feet creates cold spots and reduces the bag’s effective temperature rating.
If you fall between sizes, choose the longer option. A slightly longer bag performs better than one that’s too short, since you can cinch the hood and use a pad to fill extra space at the foot.
Yes — even when sleeping on a cot, you need an insulated pad between your body and the sleeping bag’s underside. Air circulation beneath the cot pulls heat away from your back, and the sleeping bag’s compressed insulation under your weight provides minimal protection from cold air.
Pair any of our sleeping bags with an R-3.5 or higher rated pad when using a cot in temperatures below 50°F. The combination of elevation, insulation, and a quality bag creates the most comfortable sleep system for three-season camping.
Never store sleeping bags compressed in their stuff sacks long-term. Constant compression permanently damages insulation and reduces loft. Hang your bag loosely in a closet using the footbox loop, or store it in the large mesh sack included with Premium and Alpine Pro models.
Ensure the storage area has good air circulation and stays dry. Damp storage encourages mildew growth in synthetic bags and destroys down’s natural oils. Check your bag every few months and fluff it by hand to maintain loft.
