The Camp Plus S.I. is designed to provide maximum comfort for people chasing a versatile all around sleeping mat. Combining robust and durable 75D fabrics with a unique Delta Core technique which allows STS to remove over 40% of foam for a compact do-it-all mat. Built thicker than the original Camp Mat S.I. and using horizontal Delta Coring, the Camp Plus S.I. provides great value, durability and comfort.
The use of a 75D polyester makes for a tougher, more abrasion resistant base, while at 7.5cm thick, the Camp Plus S.I. provides ample cushioning for even the boniest of hips. The high 4.3 R-value also means you can use it all year round. All self-inflating mats feature a unique, multifunction reversible single valve, designed specifically for self-inflating mats. No more fighting re-inflation as you roll up your mat!
Delta Core technology
The Delta Coring technique is a truly innovative approach to reducing the weight and bulk of the polyurethane foam core of our Self-Inflating mattresses. The patent pending coring process removes 40% of the initial volume of the PU foam, retaining enough for optimal support and comfort, while minimising the packed weight and size of the final mattress. Importantly, this coring technique has the additional benefit of keeping the top and bottom surface of the PU foam completely intact. This ensures consistent warmth along the full length of the mattress, avoiding the vertical holes or frame-like gaps that have traditionally allowed warmth to leach downwards. The full foam surface also provides significantly improved bonding of the foam to the shell fabrics of the mattress, thereby greatly reducing the chance of delamination. The shape and size of the Delta CoresTM are adjusted across the different thicknesses of our mattresses to ensure strength and durability, while still giving the user excellent support and self-inflating performance. The horizontal Delta Coring technique is used in our Comfort Light SI, Comfort Plus SI and Comfort Deluxe SI models.
A multi-function valve specifically designed for self-inflating mats
STS have literally put a new twist on the very successful multi-function valve so it specifically addresses the inherent characteristic of self-inflating mats—that is, the problem of the foam trying to re-inflate as you’re packing up. STS have engineered the “one-way” inflation valve to be reversible and used to prevent the mat from drawing air back in. This allows you to roll the mat up as small as possible without fighting re-inflation as you go. This patent-pending valve design has the same slim profile, faster inflation than traditional screw valves, easy pressure fine-tuning and super-fast deflation rate as our air mattresses and pillows.
