Buyer’s Guide

Alps Mountaineering’s Wavelength blanket combines thermal regulation with moisture-wicking technology for outdoor enthusiasts. The key features to consider include material composition, insulation thickness, and moisture management properties.

Material Composition

Look for blankets made from synthetic materials that resist odor and maintain their shape over time. Common fabrics include polyester blends with quick-drying properties. Quality blankets will use reinforced stitching around the edges to prevent unraveling during use.

Insulation Thickness

Choose a blanket with an appropriate weight based on your intended use. Lighter options (200g) are suitable for warm weather or backup insulation, while heavier options (500g) provide adequate warmth for cold conditions. The insulation should compress easily for storage while maintaining its insulating properties.

Moisture Management

Effective moisture-wicking properties prevent the blanket from becoming soggy during use. The fabric should dry quickly after exposure to moisture, whether from dew, rain, or condensation. Check for interior drying loops or ventilation features that enhance evaporation.

Blanks should come with a stuff sack for compact storage and protection. The sack should have a volume rating that matches the blanket’s weight. Consider additional features like exterior loops for attaching to gear or built-in compression straps to reduce storage space.

FAQ

What makes the Alps Mountaineering Wavelength Blanket unique?

Unlike conventional sleeping bags, these blankets utilize a modular design that allows users to select their ideal covering extent. The included Sleep System Kit features a top sheet, bottom sheet, and comfort layer that can be arranged in various configurations, from a ultra-compact mummy-style bag to a more spread-out rectangular shape.

Each blanket weighs just 22 ounces, making them one of the lightest options available. The synthetic insulation resists moisture and maintains warmth even when wet, with a packable design that compresses to the size of a sports bottle for easy packing.

How do you choose the right length for the blanket?

The recommended length selection varies based on personal preference and how you plan to use the blanket. For a more traditional sleeping bag experience, the medium length (5’10” tall, 36” long) works well. Those who prefer more legroom or plan to sleep with pets may opt for the long version (6’2” tall, 42” long).

Each blanket includes one 42” long by 36” wide comfort layer that you can add to either the medium or long top sheets. This flexibility allows you to adjust your coverage without needing to purchase multiple blankets.

Can the blanket be used year-round?

Designed for both summer and winter camping, the blanket performs well in temperatures ranging from 40°F to -4°F (-40°C to -20°C) when used with appropriate layering. The synthetic insulation provides reliable warmth in dry conditions, but users should note that performance decreases in extremely wet or windy environments.

A proper sleeping pad is essential for maintaining warmth and comfort, as is using appropriate layers underneath. The blanket works well in temperatures where other sleeping solutions might become bulky or ineffective.

What is the pack size and shape of the Sleep System Kit?

The full system, including the comfort layer and both top sheets, compresses to a small rectangular shape measuring 13” by 8” by 4”. This makes it easy to pack in a backpack’s main compartment or side pocket, without taking up valuable space in a trekking pole sleeve.

The system is designed to be space-efficient for backpacking trips where weight and volume are crucial factors. The compact size allows the blanket to perform well in environments where traditional sleeping bags may be too bulky.

How does the blanket handle different sleeping positions?

The blanket’s design allows for multiple sleeping positions without bunching up or losing warmth. The top sheet’s rectangular design provides plenty of room for side sleeping, while the bottom sheet’s mummy-style fit prevents cold spots when sleeping on your back.

Users who frequently change positions during the night may need to adjust the blanket’s configuration slightly. The adjustable nature of the system means you can maintain optimal warmth regardless of your preferred sleeping position.

What materials make up the blanket?

The core insulation is made from a synthetic fiber blend that provides consistent warmth without the bulk of traditional down. Both the top and bottom sheets are constructed from 190T polyester, making them lightweight yet durable for outdoor use.

The included comfort layer uses the same synthetic insulation but with a slightly softer feel, allowing for better air circulation while maintaining warmth. All materials are designed to resist compression and maintain their shape over time, even with regular use.
