Start your adventure feeling fresh and energised with the Sea To Summit Self-Inflating Large Rectangular Sleeping Mat, combining compact comfort and convenience for camping and beginner backpacking. Made with certified recycled 75D polyester fabric and featuring an R-Value of 4.2, this sleeping pad is durable and well-insulated to provide 3 season warmth during your outdoor adventures.

At 4cm thick, it offers lightweight comfort to achieve quality sleep. With a large Rectangular Shape, you can spread out comfortably to find your ideal sleep position.

This is an essential, budget-friendly sleeping mat if you believe a great day in the wild starts with a restful night's sleep. The Body-mapped Air Zone technology features smaller, more tightly packed cut-outs where your weight is heaviest like at your torso for the highest support, and larger, more spaced out cut-outs at lower pressure areas to ensure a lightweight design. You get adjustable firmness at your fingertips with the XPEL Valve allowing you to dial in the feel - you can let a little air out for soft, cloud-like comfort or keep it firm for extra back support. 

Key Features:

  • R-Value of 4.2: Tested for 3 season warmth.
  • Certified Recycled 75D Polyester: Durable base and top material to withstand regular use, while gearing you up with environmentally preferable fabric for eco-conscious camping.
  • Lightweight Comfort With 4cm Thickness: Provides just-right comfort that helps shield you from cold, hard or uneven terrain.
  • Body-mapped Air Zone Technology: Maximises warmth and support under your core while keeping the overall weight down with strategically positioned and shaped cut-outs. 
  • Spacious Rectangular Shape: Accommodates rolling during the night, back sleepers and side sleepers, with room to spread out comfortably so your fingers and toes don’t have to come in contact with cold ground. 
  • Low-profile XPEL Valve: Featuring a one-way inflate port and deflate port for easily adjustable firmness, the XPEL multi-purpose valve provides convenience to get the inflation just right. When deflation is required, flipping the valve over encourages air to escape efficiently without re-entering for space-saving packing. 
  • Includes Side-Loading Stuff Sack: For easy, no-fuss and secure storage that cinches your rolled-up sleeping mat in place during your travels.
Sea To Summit self-inflating sleeping mats feature an open-cell form that draws in air through an easy-to-use valve, expanding without the need for an air pump for fast, hassle-free inflation and easy packability. For personalised comfort, a small degree of additional air may be added through manual inflation.
The shape of your sleeping mat can influence your quality of sleep and overall camping experience - with the right shape for you being based on personal preference or your specific camping adventure. Sea To Summit contoured sleeping mats accommodate various sleep positions - back sleepers, side sleepers and rolling over during the night - providing additional room in the torso while limiting bulk, weight and packed volume. Rectangular sleeping mats provide fuller coverage for campers that prefer to spread out during the night, and don’t mind carrying a little extra weight.
