Description

The Ultralight Insulated is a women's insulated mattress from Sea To Summit.

It incorporates a single layer construction to provide a mattress that is ultra light and compact but still provides you with good comfort. It features the Air Sprung Cell™ technology, which offers higher capacity air cells thanks to the TPU baffles that connect the top to the bottom layers fabric. This design allows the two sides of the mattress to be spread further apart creating larger air pockets when inflated while using less fabric.

This is a 3-season mattress, featuring a R-Value of 3.3, that will provide you with a sufficient level of insulation to accompany you throughout the year. This is achieved by using Thermolite insulation in combination with Exkin PlatinumThermolite is present in the cells and will help limit heat loss while Exkin Platinum will reflect your body heat for optimal insulation.

This mattress has a shape specially adapted to the female body for a personalized comfort.

All Sea To Summit mattresses come with a storage bag that has an integrated Air stream pump. There is also a repair kit containing six self-adhesive puncture repair patches and a replacement check valve to ensure long-lasting use of the product.

Technologies :

- Thermolite: Our air-sprung insulated sleeping mattresses use THERMOLITE® insulation, designed to provide excellent lightweight warmth and superior durability. THERMOLITE® insulation lofts up inside the air sprung cells to prevent convective heat transfer from your warm body to the cold floor.

- Exkin Platinum: this is a very light and quiet non-woven fabric with a thin metallic layer applied to the surface. 
Exkin® Platinum Thermal Technology reflects heat back to the user to minimize radiant heat transfer.
