One Bag, Endless Adventures. The Most Versatile 3‑Season to Winter Sleep System.
Stop packing multiple bags for different trips. The ATEPA ELEMENTS 600 is the all-in-one sleep solution engineered for the modern adventurer. With a generous extra-wide rectangular shape, a detachable hood, and a versatile design that converts into a quilt, poncho, or double bag, this 600g down-filled system adapts to every scenario. Rated for comfort down to 39.2°F (4°C), it’s the perfect partner for cool-weather backpacking, car camping, or even a cozy night on the couch.
Why the ELEMENTS 600 is the Ultimate Adaptive Sleep System:
✅ EXTRA-WIDE RECTANGULAR COMFORT
Tired of feeling confined? With an extra-wide 35.4-inch girth, this sleeping bag gives you room to stretch, turn, and sleep naturally. The envelope-style design prioritizes comfort over restrictive warmth, making it ideal for side sleepers and anyone who values space.
✅ 3‑IN‑1 VERSATILITY: SLEEPING BAG, QUILT, & PONCHO
One purchase, three pieces of gear:
-
Full Sleeping Bag: Zip up with the detachable hood for maximum warmth.
-
Top Quilt or Blanket: Remove the hood and unzip fully for a spacious, down-filled blanket perfect for milder nights or indoor use.
-
Wearable Poncho/Shawl: Use the blanket as an ultra-warm layer around camp on chilly mornings or evenings.
✅ ZIPS TOGETHER TO CREATE A DOUBLE BAG
Adventure with a partner? Two ELEMENTS 600 bags zip together seamlessly to create a spacious double sleeping bag, perfect for couples' camping trips without the need for a separate, bulky double bag.
✅ HIGH-PERFORMANCE 600G DOWN INSULATION
Filled with 600 grams of 650+ fill power duck down, this bag delivers serious warmth for its weight. The advanced 3D baffle box construction prevents down from shifting, ensuring even insulation and eliminating cold spots across its wide surface.
✅ INTEGRATES WITH YOUR SLEEPING PAD
Included three adjustable straps let you securely attach the bag to your inflatable sleeping pad (up to 25” wide). No more sliding off your pad in the middle of the night—stay locked in place for a stable, comfortable sleep.
