The Alpkit SkyeHigh 500 is a lightweight, 3-season down sleeping bag designed for wild campers, backpackers, and thru-hikers who want reliable warmth without breaking the bank. With a comfort rating around 2°C and a lower limit of -3°C, it’s built for spring through autumn use in temperate climates. While it doesn’t compete with ultralight alpine bags on weight or fill power, it offers exceptional value, smart design, and real-world performance that makes it a favourite among UK-based outdoor enthusiasts.
Materials and Construction
The SkyeHigh 500 uses RDS-certified duck down with a fill power of 650+ IDFB, striking a balance between warmth, compressibility, and cost. The outer shell is made from 40D ripstop nylon with a C0 DWR coating, offering water resistance without harmful fluorocarbons. It’s not fully waterproof, but it sheds condensation and light moisture well.
The bag features box-wall horizontal baffles with trapezoidal side baffles, which prevent down migration and cold spots. This construction is more thermally efficient than stitched-through designs and helps maintain loft over time. The inner lining is soft and breathable, and the stitching is clean and durable.
The draft collar and adjustable hood seal in warmth, and the two-way zip allows for ventilation at the feet—ideal for warmer nights or temperature regulation. The zip is smooth and snag-resistant, with a decent baffle to prevent heat loss.

Weight and Packability
Weighing in at approximately 1,050g, the SkyeHigh 500 isn’t ultralight, but it’s competitive for a 3-season down bag in this price range. It packs down to a moderate size, fitting easily into a 30–40L rucksack with room for other essentials. The included nylon compression sack is functional but not waterproof, so a dry bag is recommended for wet conditions.
Compared to premium bags like the Rab Mythic Ultra 180 or Pipedream 400, the SkyeHigh 500 is bulkier and heavier, but it costs significantly less and still delivers solid performance.
Warmth and Temperature Ratings
Alpkit rates the SkyeHigh 500 with a comfort rating of 2°C and a limit of -3°C, making it suitable for most UK wild camping conditions outside of winter. Users report staying warm in temperatures down to freezing, especially when paired with a good mat and layered clothing.
The roomy cut allows for natural movement and layering inside the bag, though it may reduce thermal efficiency slightly compared to tighter alpine designs. Still, the bag lofts well and retains heat effectively, even in damp conditions.
Fit and Comfort
The SkyeHigh 500 is available in Regular and Long lengths, with Left or Right zip options. The cut is comfortably spacious, allowing for a relaxed sleep position and easy movement. It’s ideal for side sleepers or those who dislike the restrictive feel of mummy bags.
The hood cinches down snugly without feeling claustrophobic, and the internal draft collar adds a layer of insulation around the neck. There’s also a small internal pocket for valuables or electronics, which is a nice touch for keeping essentials close.

Durability and Long-Term Use
The materials and construction are built to last. The 40D nylon shell resists abrasion and punctures, and the down fill maintains loft well with proper care. Users report years of reliable use with minimal degradation, provided the bag is stored uncompressed and kept dry.
Alpkit offers a repair service and stands behind its gear with a solid reputation for customer support. The bag is backed by their Alpine Bond, which covers defects and performance issues.
Use Cases and Versatility
The SkyeHigh 500 is ideal for:
- Wild camping in spring, summer, and autumn
- Thru-hiking and backpacking in temperate climates
- Bikepacking and bivvy setups
- Budget-conscious alpine trips in mild conditions

It’s not suitable for deep winter or high-altitude expeditions, but for most UK and European conditions, it’s more than capable.
