Light, breathable and made for warm nights

The Sierra Designs Cloud 35 °F (+2 °C) is designed for those who sleep warm and move freely.
It’s not just a lighter version of the Cloud 20 – it’s a purpose-built summer system that blends technical performance with pure comfort.
No zippers, no drafts, no noise – just the kind of sleep that makes you forget you’re outdoors.

Zipperless design – effortless sleep without limits

Instead of a zipper, the Cloud 35 uses a soft overlapping comfort opening that naturally seals around you.
The contoured hood and anatomical footbox create a balanced thermal shape that allows you to stretch, turn, or curl up as you would in your own bed.

800 Fill DriDown™ insulation – light warmth that lasts

With 800-fill hydrophobic DriDown™ insulation, the Cloud 35 keeps its loft and warmth even when exposed to moisture.
At a comfort rating of +2 °C / 35 °F, it’s perfect for mild nights in the backcountry, vanlife adventures, or warm alpine bivies where every gram matters.

Sustainable materials, built to last

Made with recycled 15D nylon and a PFAS-free DWR finish, it’s soft, breathable, and durable.
Every bag uses RDS-certified down, ensuring the highest standards of animal welfare and product ethics.

Our take – Cloud 35 °F (+2 °C) at Campanions

Some sleeping bags are built for survival; this one’s built for sleeping well.
The Cloud 35° is for those who chase light packs, warm nights, and real rest after long days outdoors.
It’s comfort, simplified – and proof that less weight doesn’t mean less sleep.

💬 Campanions Tip:

The Cloud 35 °F (+2 °C) runs true to size and fits comfortably close for better warmth retention.
Its natural, zipperless shape allows free movement for side sleepers and relaxed sleep positions.

Regular: best for users up to 6 ft (183 cm) – efficient warmth, balanced pack size.
Long: ideal for those up to 6'6" (198 cm), or for anyone who prefers more legroom or extra layers at night.

🌿 Pro tip: If you sleep warm or travel light, go for the Regular.
If you tend to stretch out or like extra comfort space, the Long makes all the difference.
