Mummy sleeping bag High Peak Ultra Pak 500 ECO – synthetic insulation, dark green/red

The High Peak Ultra Pak 500 ECO is a mummy-style sleeping bag designed for outdoor camping and hiking. With a tapered shape and contoured hood, this sleeping bag focuses on conserving body heat while remaining compact for backpacking. The synthetic ECO insulation provides thermal performance that is suitable for multi-season use, while the two-tone dark green and red shell gives a practical, low-visibility appearance for natural environments.

Advantages

The mummy cut and contoured hood reduce heat loss by minimizing internal air volume and concentrating insulation around the head and torso. Synthetic ECO filling retains insulating properties when damp, dries faster than down, and is easier to maintain. The lightweight construction and packability make the Ultra Pak 500 ECO convenient for hikers who need a balance between thermal efficiency and carry weight. The outer fabric in dark green/red offers a durable, outdoor-oriented finish that resists visible dirt.

Suitable for

• Backpacking and multi-day hiking where compact, lightweight sleep gear is required
• Three-season camping (spring, summer, autumn) in temperate climates
• Campsites, shelters, and bivouac situations where synthetic insulation is preferred

When it may not be suitable

This sleeping bag may not be appropriate for extreme cold conditions or high-altitude expeditions that require specialized cold-weather gear or very low temperature ratings. It is also less suitable for users who prefer the compressibility and warmth-to-weight ratio of premium down fillings.

Key specifications

• Style: Mummy-shaped with contoured hood
• Insulation type: Synthetic ECO fill
• Shell color: Dark green and red two-tone
• Intended use: Backpacking, camping, multi-season
• Packing: Designed for compact storage and transport

How to use

Unroll the sleeping bag on a sleeping pad inside a tent or shelter to provide a flat, insulated surface underneath. Pull the contoured hood over your head and use the zipper to adjust ventilation along the torso; closing the hood and zipper will help retain warmth in cooler conditions. After use, air the sleeping bag thoroughly until dry, then store it loosely in a dry place or in a breathable storage sack to preserve insulation loft and prolong service life.

What to consider before purchase

• Expected temperature range and seasonal requirements for your trips
• Preference for synthetic insulation versus down in terms of wet-weather performance and maintenance
• Pack size and weight constraints for your backpacking setup

Usage recommendations

For best thermal performance, use the High Peak Ultra Pak 500 ECO together with an insulated sleeping pad, dress in a dry base layer, and ventilate slightly to regulate condensation. Regularly clean and dry the bag according to care instructions to maintain insulation loft and longevity.
