ROCK FRONT All Season System UL

The All Seasons System is a two-layer sleeping system. The inner layer is the Cube UL Bag, and the outer layer is the Cube UL Quilt, which consists of a down blanket and a sheet for the mat. The elements of the system can be used separately or together. The combination of these products creates a summer, demi-season, and winter sleeping set for temperatures ranging from +10°C to -15°C / from 50°F to 5°F

The All Season System is made from ultra-lightweight nylon and insulated with premium 870+ Fill Power goose down. It combines comfort with the lightness and compactness of lightweight gear.

The Cube UL Quilt is designed for summer adventures and camping when you need to sleep as comfortably as at home. It is a quilt and a sheet for a mat that are zipped together to make a spacious and comfortable sleeping system. It has everything you would have in your own bed: a sheet, a blanket, and a pillow. The updated sheet has a larger pillow compartment, a lighter weight, and color coding for easy reference.

With zips on both sides and drawstrings at the top and bottom, the sleeping system can be ventilated from either side, allowing you to adjust the temperature throughout the night. It is ideal for summer backpacking and camping or for traveling in warm climates.

• The feeling of being in a home bed with a blanket, sheet, and pillow.
• The increased interior space allows you to sleep in a comfortable position.
• The zippers and drawstrings allow you to adjust the temperature in any part of the sleeping system.
• The pillow cover securely keeps the pillow in the right position all night; it won’t slip, and it’s always under your head.
• Pleasant-to-the-touch fabrics make sleeping in the system comfortable even without thermal underwear or a liner.

The Cube UL Bag is designed for the off-season and cool summer nights. It is an anatomically shaped down sleeping bag with an adjustable hood and a protective strip along the zip, which helps to keep you warm.

Its minimalist design and compact size make it ideal for fast&light travel or bike trips that require ease of use and minimal weight and volume.

The optimal length zipper allows you to get in and out of the sleeping bag comfortably. The spacious footbox provides comfort in the foot area. An internal pocket holds a phone, power bank, or other valuables.

For winter adventures, we recommend taking the All Season System as a complete set. You don’t need to buy a separate winter sleeping bag; just put the demi-season sleeping bag inside the summer quilt to get a sleeping set for temperatures from -10°C to -15°C / 14°F / 5°F In this way, you can get the most out of your own equipment. Moreover, the system has significant advantages over a classic winter sleeping bag:

• One sleeping set for traveling all year round. The sleeping system combines four pieces of sleeping equipment. The whole set keeps you warm more efficiently, reducing the weight of your backpack and the cost of equipment.
• With Cube technology, the sleeping system is 20% lighter and has improved thermal properties. Cube-shaped down packs are optimally sized and filled. They retain more air than regular shaped cells, keeping you warm in cold weather. With this design, the insulation is always in the right place.
• The ability to regulate temperature at all levels. You can unzip the inner sleeping bag inside the system, open the outer quilt on the left or right side, or open the bottom of the quilt to ventilate the system in the foot area.
• Two separate layers of insulation ensure reliable heat retention. The down packs of the inner and outer layers overlap each other’s cold zones, providing uniform thermal insulation down to -15°C.
• The sheet maintains the integrity of the entire system. It securely connects your pad, pillow, and inner and outer layers into a single system that won’t slip or twist, even when you’re actively moving during sleep. Also, the sheet allows you to use two mats at the same time—the main one and an additional one—if you don’t have a warm enough winter mat or if you want to use a foam mat to protect your inflatable mat from punctures.
• The inner layer is protected from condensation. During long winter travel, moisture can accumulate inside the sleeping bag. With a two-layer system, condensation is only possible in the outer layer. When camping, a thin outer layer is much easier to dry than a voluminous winter sleeping bag.
