How does the egg design help me?
Measuring 225×95cm, the ergonomic egg shape provides generous elbow and knee room, allowing side sleepers to turn without feeling restricted.

Is the sleeping bag packable?
Yes. Despite its spacious dimensions, the down fill compresses effortlessly into the supplied compression sack for convenient travel.

Absolutely. Sleepolix is versatile enough for mountain camping, campervan tours, cabin weekends, or as a premium plush duvet for overnight house guests.

How do I care for the down?
Spot clean where possible or gentle machine wash on a delicate down cycle with down-safe detergent, then tumble dry on low with wool dryer balls.

Does the zipper snag easily?
Not at all. The heavy-duty two-way zipper system includes anti-snag guard webbing for smooth, reliable nighttime opening.

What outer fabric is utilized?
The outer shell features ripstop, water-resistant fabric to shed condensation, light rain, and tent dampness effortlessly.
