Synthetic Sleeping Bag Fjord Nansen TROMS MID — T Limit −5°C / 1,466 g

Synthetic Sleeping Bag Fjord Nansen TROMS MID

Synthetic sleeping bag Fjord Nansen TROMS MID uses resilient MICROFILL SUPER-THERM microfiber insulation beneath a POLI RIPSTOP shell and a vapour-permeable nylon lining. Its −5°C limit, 1,466 g weight and 178 cm maximum user height describe this left-zip version.

Insulation and Fit

MICROFILL SUPER-THERM is described by the manufacturer as soft and lightweight, with microfiber construction that gives the fill resilience and thermal insulation. The pleasant-to-touch inner fabric allows water vapour through to help maintain the sleeping bag's microclimate. The ergonomic mummy shape reduces the unneeded space that the body must heat. A thermal collar at the shoulders adds insulation around the opening.

Hood, Zipper and Storage Details

• Adjustable contoured hood helps reduce heat loss from the head, with one-hand adjustment.
• Left-side high-quality zipper; a fluorescent pull is easier to locate at night.
• 3 cm ANTI-BITE protection helps prevent fabric snagging in the zipper; an internal thermal strip limits heat loss along it.
• Shoulder-level thermal collar.
• 20 × 20 cm inner pocket for small valuables, with a card for the owner's details.
• Compression sack with snap buckle included for packing.

Temperature Ratings and Testing

The manufacturer states that selected sleeping bags from each collection were tested in a Weiss climate chamber using a 16-element DIANA manikin under PN-EN 13537:2004, and that ratings for the range were calculated from those results. T max is the upper comfort boundary, T comfort is the reference for a standard woman, T limit for a standard man, and T extreme indicates survival conditions with hypothermia risk rather than a normal sleeping temperature.

Storage and Fill Durability

The manufacturer recommends storing the bag unfolded or in a storage bag, not left compressed in its compression sack, to maintain insulation performance. It reports that the MICROFILL SUPER-THERM material and sleeping bag retained thermal properties, thickness and elasticity through a ten-wash test with spinning.

Technical Specifications

The manufacturer says TROMS received a “Good Choice” distinction from PODRÓŻE magazine.
