01
Coleman Brazos 20°F Sleeping BagBudget
The car camping baseline. Warm, heavy, inexpensive. Correct for everyone who drives to their campsite.
7.7/10
02
Teton Sports Tracker +5°F BagBudget
Best value at this temperature rating. Outperforms its price by a measurable margin. Grant verified against three competitor reviews.
8.0/10
03
Kelty Cosmic 20°F Down BagMid-Range
Down insulation under $120. The packability advantage over synthetic is real and compresses to half the size.
8.3/10
04
Marmot Trestles 15 Sleeping BagMid-Range
Synthetic insulation performs when wet. For Pacific Northwest or shoulder season, this outperforms down bags costing more.
8.5/10
05
REI Co-op Magma 15 Down BagPremium
850-fill down at 1 lb 12 oz is exceptional value for the performance tier. Grant's primary recommendation for 3-season backpacking.
9.0/10
06
NEMO Disco 15 Sleeping BagPremium
The spoon shape eliminates the foot compression problem. Side sleepers specifically: this is the correct bag.
8.7/10
07
Therm-a-Rest Hyperion 20 BagPremium
13 ounces. Grant weighed it. The packing size is genuinely a softball. The price buys a different category of product.
9.1/10
08
11 ounces for a legitimate sleeping bag. Correct for summer backpacking. Wrong choice if your nights drop below 45°F.
8.8/10
09
Feathered Friends Swallow YF 20Premium
950-fill is the highest standard in commercial production. Lifetime warranty means you buy it once. The price is accurate.
9.3/10
10
Hyke & Byke Eolus 15°F BagMid-Range
800-fill down under $150 is the category anomaly. Construction quality trails Kelty slightly. The warmth-to-weight-to-price ratio doesn't.
8.4/10
Frequently Asked Questions
Down vs synthetic: which should I buy?
Down packs smaller and weighs less. Synthetic insulates when wet and costs less. If you camp in reliably dry conditions and backpack, choose down. If you camp in the Pacific Northwest or car camp, synthetic is fine.
What temperature rating do I actually need?
Buy a bag rated 10-15°F colder than your coldest expected night. A 20°F bag for 30°F nights is correct. People consistently underestimate how cold nights get at elevation.
Are sleeping bag liners worth it?
A silk liner adds 5-15°F of warmth and extends bag life significantly. For a $350 down bag, a $60 liner is the correct investment. Grant has one. He has not used it outdoors.
