Winter Sleeping Bag Fjord Nansen STAVOY Envelope with Hood 1°C / 2150g

Sleeping Bag Fjord Nansen STAVOY POLIESTER 1°C Envelope with Hood Sapphire

Sleeping Bag Fjord Nansen STAVOY is an envelope-shaped sleeping bag with a 3D hood designed for cold summer, warm spring, and autumn camping conditions. The model has a T lim rating of 1°C, T comfort 6°C, and T extreme -10°C, with a total weight of 2150 g. The filling is EKO LOFT HOLLOWFIBER synthetic nonwoven insulation, while the outer material is Polyester 210T RIPSTOP and the inner lining is POLICOTTON t/c 96/90 made of vapor-permeable fibers to maintain a stable internal microclimate. The universal size (218 x 85 cm) is suitable for users up to 200 cm tall. Thermal parameters are estimated based on laboratory testing of other Fjord Nansen models in accordance with EN 23537 standards.

EKO LOFT HOLLOWFIBER insulation is made of spirally twisted siliconized polyester fibers that trap air within the structure, providing warmth with relatively low weight. The fiber elasticity maintains loft and thermal efficiency during repeated use. Temperature values are determined using climate chamber testing methods aligned with EN 23537 methodology, reducing the risk of selecting an unsuitable sleeping system. According to the standard, T lim represents the lowest temperature at which a standard man can sleep comfortably, while women and cold-sensitive users should rely on T comfort values.

Features

• ➤ Warm synthetic insulation: EKO LOFT HOLLOWFIBER nonwoven filling made of spirally twisted siliconized polyester fibers.
• ➤ Envelope design with 3D hood: Provides increased freedom of movement and additional head insulation.
• ➤ Durable outer fabric: Polyester 210T RIPSTOP reinforced weave improves mechanical resistance.
• ➤ Thermal zipper baffle: Insulated tube along the zipper reduces heat loss.
• ➤ Technical zipper system: Left two-way zipper with ANTI-BITE protection and Duo drawcord adjustment.
• ➤ Comfort width: Approximately 5 cm wider than standard envelope models for improved sleeping comfort.

This sleeping bag is suitable for camping and family outdoor stays in transitional seasons. During overnight stays near Lake Burtnieks in early autumn, temperatures may drop close to the 6°C comfort level after sunset. When nighttime air approaches the 1°C limit value, the EKO LOFT HOLLOWFIBER insulation supports thermal balance inside the envelope structure. The POLICOTTON vapor-permeable lining helps regulate moisture in cool and humid lakeside conditions.
