The SUNMER double sleeping bag is a rectangular two-person design with a claimed 300GSM filling and a stated option to separate it into two single bags. Its dimensions suit buyers prioritising shared space, but the listing gives conflicting weight and temperature information, so check those details before relying on it for cold-weather trips.

What to know before buying

Listing details to confirm

Listing details are contradictory or inconsistent: weight is listed as 2.5 Kilograms in product details but 2.6kg in feature copy, dimensions appear as both 2.2L x 1.5W metres and 220cm x 150cm, and temperature guidance varies between 10°C to 0°C and 10°C to -5°C. The 300GSM filling and all-seasons wording do not establish a standardised temperature rating. Check the selected listing and intended conditions before relying on cold-weather protection. Customer feedback also reports mixed views on usable size and zipper operation, with some finding it roomy and others disputing the king-size description, and reports that the bag feels thin.

Who is it for?

A good fit for

Couples or two campers wanting one shared rectangular sleeping bag.
Buyers who may value separating the bag into two singles, as claimed in the listing.
Caravan or campsite use where the listed weight is less critical than a shared sleeping space.

Less suited to

Buyers needing a dependable, standardised cold-weather temperature rating from the supplied listing.
Hikers who need a confirmed pack weight, since the listing gives two different weights.
Anyone needing assured king-size room or consistently reliable zipper operation based on customer feedback.

Customer feedback describes the bag as comfortable and warm, and reports positive impressions of camping and caravanning use. Other feedback says it can feel thin, while views differ on whether the available space merits the king-size description and on whether the zip works smoothly. These comments matter for a two-person bag intended for outdoor use, but they do not establish a reliable cold-weather rating or settle the listing's size and weight discrepancies.

Frequently asked questions

Can this sleeping bag be used as two singles?

The listing claims it can convert into two single sleeping bags. Confirm the configuration and zips on the selected listing.

What temperatures is it intended for?

The listing gives inconsistent guidance, ranging from 10°C to 0°C in one description and 10°C to -5°C elsewhere. Treat those figures as unconfirmed rather than a dependable rating.

What are the dimensions and weight?

Dimensions are given as 220cm x 150cm in feature copy, while the product details express them as 2.2L x 1.5W metres. Weight is listed as 2.5 Kilograms in details and 2.6kg in the feature text, so verify before purchase.

Is the outer shell waterproof?

The listing describes it as water-resistant in its detailed copy, though the title calls it waterproof. Water resistance should not be taken as confirmed waterproof protection.
