Kelty vs SYWSKW Sleeping Bag Specs

Temperature Rating

Edge: SYWSKW Large Down Sleeping Bag

The SYWSKW bag boasts a 0°F comfort rating, designed for cold weather and winter camping conditions. It uses 680FP RDS certified duck down to lock in heat effectively. In contrast, the Kelty model is rated for 20°F, making it suitable for three-season camping. While both bags provide warmth, the SYWSKW offers a significantly lower temperature threshold. This makes the SYWSKW a better choice for colder environments, whereas the Kelty is optimized for milder nights.

Capacity and Size

Edge: Kelty Doublewide 20F Sleeping Bag

The Kelty is explicitly built as a 2-person, double-wide sleeping bag. It provides 64 inches of shared shoulder space and measures 84 inches in length, accommodating two adults or a parent and child comfortably. The SYWSKW is a single-person bag with a width of 33.5 inches and a length of 86.6 inches. Although the SYWSKW is longer, it is much narrower. If you need space for two people, the Kelty is the clear winner.

Insulation Material

Edge: Tie

Insulation type affects warmth and weight. The Kelty uses synthetic Cloud Loft insulation, which is compressible, quick-drying, and ultra-soft. Synthetic fill retains warmth even when damp. The SYWSKW uses premium duck down with 680 fill power. Down offers superior warmth-to-weight ratio and compressibility compared to synthetic options. The SYWSKW provides better loft and packability, while the Kelty offers reliable performance in potentially wetter conditions without the premium weight savings of down.

Weight and Portability

Edge: SYWSKW Large Down Sleeping Bag

Weight is critical for backpacking. The SYWSKW bag weighs just 2.6 pounds, making it lightweight and compact. It compresses down to roughly 7 by 12 inches, ideal for hiking where space is limited. The Kelty bag weighs 9 pounds, which is significantly heavier. This weight makes the Kelty unsuitable for long-distance backpacking. It is better suited for car camping where you can carry heavier gear. For mobility, the SYWSKW is far superior.

Included Accessories

Edge: SYWSKW Large Down Sleeping Bag

The SYWSKW model comes with an integrated 80g detachable pillow, adding immediate comfort for overnight trips. It also includes a compression bag and reflective drawcords for safety. The Kelty listing does not mention any included accessories like pillows or stuff sacks. It focuses on the bag itself with features like removable top layers and independent ventilation. The SYWSKW provides a more complete sleep system out of the box with its added pillow.

Frequently asked questions

Which sleeping bag is better for solo backpacking?

The SYWSKW model is the better choice for solo hikers. It weighs only 2.6 pounds and measures 33.5 inches wide, making it easy to carry on long trails. The Kelty option weighs 9 pounds and is designed for two people, which makes it too heavy and bulky for backpacking trips where every ounce matters.

Does the SYWSKW bag include a pillow?

Yes, the SYWSKW Large Down Sleeping Bag comes with an included pillow. This adds convenience for campers who want to minimize the gear they need to pack separately. The Kelty Doublewide does not list an included pillow in its specifications, so you would need to bring your own for shared comfort.

What is the difference in insulation between these two bags?

The Kelty bag uses synthetic insulation, which is durable and performs well in damp conditions. The SYWSKW bag uses 680 fill power down, which offers superior warmth-to-weight ratio. Down is lighter and compresses smaller, while synthetic insulation is generally more affordable and retains heat when wet.

How much shoulder room does the Kelty bag provide?

The Kelty Doublewide provides 64 inches of width, allowing two adults to sleep comfortably side by side. This spacious design is ideal for couples car camping. In contrast, the SYWSKW bag is 33.5 inches wide, which is standard for a single sleeper and may feel restrictive for two people.

Can the SYWSKW sleeping bag handle cold weather?

The SYWSKW bag is rated for cold weather conditions and features 680 fill power down insulation. It is designed to keep you warm in chilly environments. While the Kelty bag is rated for 20°F, the SYWSKW down construction typically offers better heat retention for its weight in cold scenarios.

Which bag is lighter and easier to pack?

The SYWSKW bag is significantly lighter at 2.6 pounds compared to the Kelty bag’s 9 pounds. It is also narrower, measuring 33.5 inches wide, which allows it to compress into a smaller stuff sack. The Kelty bag’s doublewide size and synthetic fill make it much heavier and bulkier to transport.

Is the Kelty bag suitable for two people?

Yes, the Kelty Doublewide is specifically designed for two people. It measures 84 inches in length and 64 inches in width, providing ample space for couples. The SYWSKW bag is a single-person mummy bag, so it is not suitable for sharing unless you are comfortable with tight quarters.
