Down sleeping bag Warmpeace Spacer 300 Oasis

This summer, treat yourself to extra comfort with the Spacer 300 sleeping bag from the Czech brand Warmpeace. Its egg-shaped design (wider and more comfortable than the mummy shape) and lightweight duck down insulation will give you a peaceful sleep wherever you are.

Warmpeace is one of the leading Czech brands for outdoor gear—a small but popular company that produces clothing, sleeping bags, sleeping pads, and hiking accessories. Their products range from practical models with excellent price-to-quality ratios for your monthly adventures, to specialized models designed for expedition use in harsh mountain conditions.

The Spacer 300 summer sleeping bag is an innovative model with a special shape, created for overnight hikes with tent or hut stays during the warmer months of the year. It is suitable for temperatures around 0°C—its comfort rating is -1°C for men and 4°C for women. This insulation performance is made possible by a filling of 300 grams of duck down with a fill power of 700 cuin, which meets the criteria for expedition and high-altitude use. The down is evenly distributed in horizontal baffles.

The Spacer 300 stands out from standard summer sleeping bags in two key ways:

1. Shape: Instead of the classic mummy shape common to most trekking models, it has an egg-like form. That’s where the name “Spacer” comes from—a sleeping bag that offers more interior space and sleeping comfort, giving you a much greater range of movement.

2. Outer fabric: It provides a high level of water resistance, with a water column rating of 1250 mm (breathing of the fabric: RET 3.7 m²Pa/W). In this model, Warmpeace includes a "moisture absorption" rating—i.e., the maximum amount of water the sleeping bag can absorb before it starts to feel wet. The 180 cm version can absorb up to 90 g of water, while the 195 cm version can handle up to 99 g.

The Spacer series features bags with hoods that include dual width adjustment in various zones, so you can fine-tune how snug you want to be during the night. The model also has a small internal pocket for storing anything you may need during the night.

Lightweight (just 730 g for the 180 cm size), compact (comes with a handy compression sack), and exceptionally spacious, the Warmpeace Spacer 300 summer sleeping bag is one of the best options for a comfortable night’s sleep—wherever your adventures take you.
