Who should buy the Peralta 25
The Peralta suits car campers, weekend backpackers and families who want a warm, comfortable bag without a premium price. The roomy rectangular shape also works well for side sleepers.
Warmth and insulation
Near Zero uses Sorona synthetic insulation, with 180 g of fill in the top and 160 g in the bottom for balanced warmth. The comfort rating is 25°F, with a comfort range of 23 to 28°F.
Comfort features
The hooded, rectangular design is 86 x 33 in. A zipper draft tube cuts heat loss, a pillow pouch holds your pillow in place, and snap loops let you attach a liner for extra warmth or cleanliness. YKK zippers keep the zipper smooth.
Packing and weight
At 2.5 lb it is light for a roomy bag. It packs to 14 x 6 in in its case and 10 x 6 in with the compression bag, so it fits easily on a pack or in the car.

Why we like it.
Warm for fall nights
A 25°F comfort rating and a 23 to 28°F comfort range cover cool-weather camping.
Roomy rectangular cut
At 86 x 33 in zipped it gives space to move, and a hood and zipper draft tube hold in heat.
Thoughtful comfort details
A pillow pouch keeps your pillow in place, and snap loops let you attach an optional liner.
Packs small for its warmth
It compresses to 10 x 6 in with the included compression bag.
Great price
At $99.50 it is a low-cost way to get a proper synthetic bag.
A few things to consider.
Rectangular, not mummy
The roomy cut is comfortable but less thermally efficient and a bit heavier than a mummy bag.
Rated for cool, not cold
It suits temperatures around 25°F and up; choose a lower-rated bag for deep winter.
Synthetic fill is bulkier than down
Sorona insulation is durable and warm when damp but packs larger than premium down.
