11 · FAQ
Questions from real buyers, answered with data
Is ALPS OutdoorZ Redwood -25 worth $184.99?
At $184.99 with -25°F rating and 932 reviews, this is a credible extreme cold bag. The price is reasonable for expedition-grade. Skip if you never camp below 0°F.
Can I use this for backpacking?
No. 11 lb makes this impossible for trail carrying. This is a base camp, vehicle, or emergency bag.
What temperature is this actually good for?
-25°F is a survival rating. Expect realistic comfort at 0-5°F. Below that, you need additional insulation.
How does it compare to down?
Polyester fill is heavier and bulkier but insulates when damp. Down is lighter but fails when wet. For cold and potentially damp conditions, polyester is more forgiving.
