Antares HD Three Season Down Sleeping bag

Three Season

Antares HD Three Season Sleeping Bag

Our most versatile unisex down sleeping bag features Nikwax® Hydrophobic Down for improved performance in wet climates.

Now featuring Nikwax® Hydrophobic Down and a ThermaCapture™ lining for advanced, lightweight warmth, the three-season Antares HD can handle just about anything from early spring to late fall. It has also been updated with our new Zoned Insulation, adding a light layer of sewn-through insulation to the bottom of the bag. This helps reduce drafts when joined with your mattress, and frees you to use your bag in a hostel or your friend’s couch–wherever you don’t need a camp mattress. We do recommend outdoor use however. It’s just more fun that way.

Temperature Ratings

Warmth You Can Trust: Considering all the variables that affect how warm you sleep, providing a single number for a sleeping bag rating can be misleading. That’s why we test all of our sleeping bags to the EN (European Norm) 13537 Standard. The following definitions will help you understand this Standard, and how to use it to find the bag that’s right for you.

Comfort Range: This is the temperature range where you can expect the bag to provide reliable warmth for a “standard” man or woman. Below this, the test’s “standard woman” will begin to feel cold.

Transition Range: In this temperature range, a “standard” man will be comfortable.

Risk Range: In this range, a strong sensation of cold has to be expected. There is risk of health damage by hypothermia. The bag should only be used in this range in an emergency, or by those with ample experience in augmenting a bag’s warmth.

Standard Woman: 25 years old, 132 lb (60 kg), 5’2” (157 cm)

Standard Man: 25 years old, 154 lb (70kg) and 5’7” (170 cm)
