Top FAQs – Ascend Sleeping Bags

Q: Are Ascend sleeping bags ISO tested?

A: Yes. Every bag in the Spring 2025 lineup—Tempest, Typhoon, and Tsunami—is tested under the ISO 23537 standard, giving you accurate temperature ratings you can rely on.

Q: What’s the difference between Regular and Long sizes?

A: Regular sizes fit users up to 6' tall. Long sizes are ideal for campers 6'1" to 6'6", offering more room to stretch and stay warm.

Q: How do I care for my sleeping bag?
