Sleep System Guide

Choosing the Right BaseSleeping Mats

A sleeping mat is the foundation of your sleep system. Your sleeping mat's primary function is to provide a comfortable sleeping surface and insulate you from the cold ground — which can be a whole lot colder than the air around you.

We challenged every aspect of conventional wisdom when we created our award-winning lineup of innovative air and self-inflating mats. Because when it comes to a great night’s sleep you can’t rest on your reputation.

Self-Inflating Sleeping Mats

Perfect for comfort focused campers who are willing to trade a little extra weight for added comfort, our self-inflating sleeping mats are easy to inflate and include plush foam to help you sleep through the night.

Comfort and warmthSleeping Bags

A quality sleeping bag is the heart of your sleep system and has the principal job of protecting you from losing body heat into the surrounding air. When choosing a sleeping bag you should consider the temperature and climate you'll be sleeping in and the desired weight and packability needed.

The type of adventure you're planning to bring your sleeping bag on will vastly change how you prioritise weight, packed size and fill type. If you are going on a thru hike, weight and packed size will be crucial. If you plan on a paddling trip, a synthetic bag that dries more quickly and can still insulate when wet should be your choice.

You may find that a quilt is the right choice so you can pair it with a sleeping bag during extra cold temperatures or use on its own when the nights are warm and you don't need a full sleeping bag.

Warmth, Comfort and CleanlinessSleeping Bag Liners

When assembling your perfect sleep system, a sleeping bag liner forms the next-to-skin layer that adds versatility to the entire system. It can increase comfort, add warmth in cooler temperatures and wick moisture from your skin in warmer, more humid conditions.

Using a liner also significantly reduces the frequency with which you will need to wash your sleeping bag and therefore extend its life. Along with correct storage, this is the single simplest thing you can do to protect the investment you made in a quality sleeping bag. And – not needing to replace an item is the greatest contribution towards sustainability you can make.

Thermal Boosting Sleeping Bag Liners

The Reactor performance liners can add warmth to your sleep system in cool or cold conditions by trapping extra insulating air in the hollow-core fibers and infra red-absorbing pigments within the fabric. The new drawcord footbox available in many liner options also provides an extra layer of versatility allowing you to open or close the footbox to regulate temperature further for the optimal sleep.

Moisture Wicking Sleeping Bag Liners

Our Breeze series of liners helps to wick moisture away from the skin effectively with its Coolmax fibers woven throughout. This wicking process reduces the clammy feeling you may get in warm or humid conditions, especially if you are using a sleeping bag that does not have the soft, breathable lining fabrics and ventilating zippers that are staples in most Sea to Summit sleeping bags.

Free Flow Zip System

Our Free Flow triple-zip design ensures your sleeping bag retains maximum warmth and efficiency when needed and multiple ventilation options when it's not. The half-zip on one side of the bag provides freedom of movement for both arms, additional ventilation and allows the top third of the bag to be folded down as a mini quilt when sleeping in warmer temperatures.

Zip Coupling

Designed to pair side by side, each person sleeps in their own bag enabling each of you to take advantage of your bag's unique insulation zones, hood and footbox features - perfect for cosy adventures for two. Bags with full-length zips on both sides can also be coupled together with other pairing bags.

The QuiltLock™ system uses the snap locks located at the shoulder and foot end of Sea to Summit sleeping bags plus the quilt footbox / quilt straps to secure a quilt to the sleeping bag. This adds thermal performance and versatility to your sleep system: your integrated quilt now works for ultralight summer adventures and turns your three-season bag into a four-season sleep system.

Pillow Lock™ System

The Pillow Lock™ System comprises of self-adhesive hook-and-loop patches which are supplied with all Sea to Summit sleeping mats. Attached to your sleeping mat, these patches secure your pillow and prevent it slipping – yet they will not snag on clothing or other lightweight fabrics.
