BISINNA 0° Winter Sleeping Bag, Black, 2.3kg Right Zipper — 480gsm Hollow-Fiber, Water-Resistant for Cold-Weather Camping

BISINNA 0 Degree Winter Sleeping Bag is a high-loft, 480gsm hollow-fiber insulated adult sleeping bag built to keep you warm and compact on cold-weather camping, backpacking, and outdoor trips.

Engineered from a water-resistant outer shell and soft 210T pongee lining, this sleeping bag balances warmth, durability, and portability. With a 480 grams per square meter hollow cotton fill and a half-circle hood with adjustable drawstring, it provides more insulating loft than standard summer bags while compressing down into a small sack for travel. The bag also converts to a blanket or zips together with a partner’s bag for versatile campsite comfort.

How warm is this sleeping bag for cold-weather camping?

The BISINNA sleeping bag uses 480gsm hollow-fiber insulation to trap heat and reduce convective loss, giving reliable warmth in lower temperatures. The adjustable hood and snug foot box retain body heat where it matters most, and the water‑resistant shell helps shed light moisture.

• Insulation: 480 g/m² hollow cotton fill for high loft.
• Temperature guidance: suitable down to roughly 23°–50°F depending on individual tolerance and layering.
• Design: half-circle hood with drawstring to minimize heat escape.
• Shell: water-resistant outer fabric to resist dampness.

Can I pack it small and carry it on hikes or backpacking trips?

Yes — the BISINNA compresses into a compact sack and remains light enough for multi-day trips. The included compression sack reduces packed volume, and the 5 lb weight is manageable for most overnight and car-camping adventures.

• Packed dimensions: approximately 41 x 27 cm (16 x 10.6 in) compressed.
• Weight: about 5 pounds for a balance of warmth and portability.
• Carry convenience: comes with a compression sack for easy attachment to packs.
• Care: wipe-clean outer shell; machine-washable for deep cleaning.

How does the zipper and combination feature improve usability?

The sleeping bag uses SBS two-way zippers that allow smooth opening and ventilation control. Two bags—left-zip and right-zip versions—can be zipped together into a double sleeping bag, or you can fully unzip a single bag to use it as a blanket or quilt at camp.

• Two-way SBS zipper for smooth operation and ventilation control.
• Left-zip + right-zip compatibility for creating a double bag.
• Bottom separated zipper lets you release foot ventilation without unzipping fully.
• Fabric-engineered zipper channel reduces snagging and fabric pull-in.

What materials and finishes help with comfort and durability?

High-quality 210T polyester for the shell and 210T pongee for the lining deliver a soft interior and abrasion resistance on the outside. The hollow-fiber filling keeps loft over many uses, and a soft pillow included with the bag adds neck support for better sleep without bringing a separate cushion.

• Outer: 210T polyester water-resistant shell for light moisture protection.
• Lining: 210T pongee for comfortable, breathable skin contact.
• Fill: hollow cotton fiber designed to maintain loft and warmth.
• Extras: soft pillow included for neck support and comfort.

Who is this for? The BISINNA 0 Degree Winter Sleeping Bag suits campers, backpackers, and anyone needing a warm, packable sleep system for cooler seasons. It’s a solid pick for weekend car camping, multi-night hikes where low temperatures are expected, or shared overnight setups when you want to zip two bags together. If you want a durable, easy-care sleeping bag that converts to a blanket and compresses for travel, this model offers a practical balance of insulation, features, and convenience without extra bulk.
