The reference standard in sleeping mats - comfort, low weight, durability, 4-season warmth and small packed size. The synthetic microfiber insulation is bonded to the top and bottom for superior efficiency. The warmth to weight ratio of our SynMat is superior to traditional sleeping mats and its 9cm thickness offers outstanding support.

Thermolink

This bonded fibre weighs less and packs down smaller than competing synthetic fills, making our bags lighter and more compact while maintaining comfort and durability. The secret is in the manufacturing process: thousands of hollow fibres are sandwiched between a high-density thermal barrier and a fine, soft, body-conforming radiant retention layer to form one continuous sheet of Thermolink fibre. As it is one continuous layer, there aren’t any gaps for heat to escape, leading to better performance than traditional baffled fills.

Sac sleeping bags are made using lightweight and highly breathable 20-denier Vapour Vent fabric. This strong, compressible and highly breathable fabric uses a tight weave that keeps the insulation in but allows water vapour to escape. This reduces the possibility of clamminess and allows the insulation to loft fully for maximum performance.

Used inside The Nitrous is a collection of 3D, vertical V-baffles filled with 800+ loft DWR down; a full zip allows venting while the box foot prevents cold spots; and there’s a draft tube, three-quarter hood and internal chest drawcord. The Nitrous is also versatile. Other features include Vapour Vent fabric with a water-repellent coating and a zip protector on the YKK zip.

800+ loft DWR-treated duck down is our premium choice – a must for the gram counters. This high-lofting white duck down delivers luxurious warmth at a fine, feathery weight. This down has excellent compactability and loft recovery. Down is the best insulation for lightweight sleeping bags due to its loft, compressibility and durability. However, this golden fibre has a failing: its ability to insulate drastically decreases when it is wet.

Nitrous sleeping bags are made using lightweight and highly breathable 15-denier Vapour Vent fabric. This strong, compressible and highly breathable fabric is ‘downproof by construction’: the tight weave keeps the down in but allows water vapour to escape. This reduces the possibility of clamminess and allows the down to loft fully for maximum performance.

Down is the best insulation for lightweight sleeping bags due to its loft, compressibility and durability. However, this golden fibre has a failing: its ability to insulate drastically decreases when it is wet.

The solution is now here – DWR DOWN. This down has been selected to meet our rigorous standards, with a durable water-repellent (DWR) treatment applied after the cleaning and sorting process.
The benefits of DWR DOWN are:

• It absorbs less water in damp conditions
• It retains higher loft (insulation) in damp conditions
• It dries faster

SynMat HL Winter is designed to be the lightest 4-season sleeping mat on the planet. Tapered design, 20 denier fabric, microfiber insulation and 9 cm  thickness create a balance of features that respect the most weight and bulk conscious winter campers. This mat also offers the warmth needed for cold sleepers in spring and summer conditions. It packs to an extremely small size and it's tapered profile fits into the smallest tents. 

Next-to-skin comfort and anti-slip GripSkin honeycomb-pattern coating. Laminate is air tight and impervious to hydrolysis. 

Clever Pumpsack included: The Schnozzel Pumpbag allows you to inflate the mat instantly while preventing humidity from your breath affecting the insulation. It also doubles as an ultra lightweight compression stuffsack.

Thermolink

This bonded fibre weighs less and packs down smaller than competing synthetic fills, making our bags lighter and more compact while maintaining comfort and durability. The secret is in the manufacturing process: thousands of hollow fibres are sandwiched between a high-density thermal barrier and a fine, soft, body-conforming radiant retention layer to form one continuous sheet of Thermolink fibre. As it is one continuous layer, there aren’t any gaps for heat to escape, leading to better performance than traditional baffled fills.

FEATURES

• Includes an Airstream™ Pump that is integrated into the stuff sack for quick and easy inflation.
• Air Sprung Cells™ conform to your body shape, providing a more even dispersion of pressure across the mattress for a more comfortable nights sleep
• Dual Layer construction uses two independent high resolution layers, giving greater sensitivity by distributing your body weight and shape over more cells. The two layers are offset for more uniform insulation and cushioning.
• Exkin Platinum® is a very lightweight and quiet metallised fabric. Exkin Platinum® thermal technology reflects radiant heat back to the user.
• THERMOLITE® insulation lofts up inside the Air Sprung Cells™ to prevent convective heat loss from your warm body to the cold ground.
• Multi-function valve provides fast inflate, deflate and easy fine-tuning for personalised comfort.
• Extrusion TPU lamination is vastly superior to roll-to-roll lamination, helping to prevent delamination.
• Includes a repair kit for easy puncture repair in the field.

At Sea to Summit we set out to design a mat that was better than what was already available. ‘Better’ is of course a very subjective ambition: while we could have made the lightest, or the most compact mat ever designed, we ultimately went back to why we carry a sleeping mattress into the wild in the first place — to give us a better night’s sleep. We’re really proud to present what we consider to be the most comfortable sleeping mattresses available. Happy sleeping!

FEATURES

• Includes an Airstream™ Pump that is integrated into the stuff sack for quick and easy inflation.
• Air Sprung Cells™ operate in the same way as a pocket spring mattress, as each cell deforms independently the mattress conforms to your body shape which feels softer and more comfortable with more body contact area and even dispersion of pressure.
• The Comfort Light range features dual layer construction in the torso for maximum comfort and insulation, and single layer construction in the head and legs where it’s needed less.
• Exkin Platinum® is a very lightweight, quiet non-woven fabric that has a thin metalised layer applied to the surface. Exkin Platinum® thermal technology reflects radiant heat loss back to the user.
• The THERMOLITE® insulation lofts up inside the Air Sprung Cells™ to prevent convective heat loss from your warm body to the cold ground.
• Multi-function valve integrates an inflate port with a one-way valve to prevent air loss before you seal the valve, a rapid air dump deflate port, and a fine tune button to adjust for comfort, in one compact, low profile unit.
• Extrusion TPU lamination is more durable, consistent and is vastly superior to roll-to-roll lamination, helping to prevent delamination.
