Hotcore | Cooper R-7 Sleeping Bag (+7°C)

When the summer days are long and the nights stay comfortably cool, you don't need a heavy, bulky mummy bag weighing you down. The Hotcore Cooper R-7 is the minimalist’s dream—our smallest and lightest sleeping bag, designed for those perfect +7°C Maritime nights. Whether you’re bike-packing down the South Shore, hostelling through Europe, or just need a compact layer for a backyard sleepover, the Cooper R-7 delivers. It’s packed with clever, "why-didn't-I-think-of-that" features, like a dedicated pillow pocket and tactile cordlocks that you can identify by touch in the middle of the night. Light, versatile, and incredibly packable, it's the bag that proves you don't need a massive pack to have a massive adventure.

• Ultra-Compact Performance: Weighing in at just 2.1 lbs (0.95 kg), this bag compresses down to an extreme compact size, making it the go-to choice for travel and light-and-fast backpacking.
• Integrated Pillow Pocket: A built-in sleeve keeps your pillow secure through the night, or can be stuffed with a soft jacket to create a comfortable headrest on the fly.
• Anatomical Shoulder Drawcord: Allows you to cinch the bag around your shoulders to trap heat in and keep the midnight breeze out, maximizing your comfort on cooler nights.
• Intuitive Nighttime Controls: Uses different shapes and colors for the cordlocks, so you can easily adjust your hood or shoulder cinches by feel without needing to find your headlamp.
• Versatile 2-Way Zipper: Features a reversible, high-visibility slider and a foot-venting option, allowing you to regulate your temperature if the morning sun starts to warm up the tent.
• Sleeping Pad Security: Includes four fabric loops designed to anchor the bag to your sleeping pad (cord not included), ensuring you don’t slide off your mat in the middle of a dream.
• Expandable Design: Can be zipped together with any other Hotcore sleeping bag of the same dimensions to create a double bag for couples.
