The Nemo Eclipse All-Season Sleeping Mat Long Wide is an exceptionally engineered, high-performance pad designed to deliver restful sleep across every season, from mild backcountry summers to harsh sub-zero conditions.

Engineered with a plush 4 inches of height, this air-supported sleeping surface uses internal Spaceframe baffles to create structural integrity and eliminate wobble. Within each baffle, two layers of Thermal Mirror insulation are freely suspended to provide impressively quiet warmth across all seasons. The subtle body-mapped contouring prevents sleepers from rolling off the edges at night. Equipped with an impressive 6.2 R-value, it effectively insulates outdoors lovers against frozen terrain, making it an essential choice for both demanding backpacking treks and serious winter camping expeditions.

Despite its thick, stable foundation, the pad maintains a remarkably lightweight profile that packs down compactly into any haul bag. Inflating the pad is quick, efficient, and hygienic thanks to the included Vortex pump sack, which prevents moisture from accumulating inside the air chambers, while the sleek, low-profile Laylow valve allows for fine-tuned micro-adjustments to customized firmness.

Offering an optimal balance of warmth, packability, and luxury comfort in a classic rectangular shape, this insulated mat provides a dependable sleep solution wherever your adventures lead.

Key Features:

• Long Wide Size: 193 x 64cm.
• 4 Inches of Air-Supported Cushioning: Provides generous depth and plush ground clearance to cushion side sleepers and absorb uneven terrain.
• Spaceframe Baffles: Internal structural trusses maintain edge-to-edge pad stability, eliminating springiness and minimising surface motion.
• Thermal Mirror Insulation: Nemo’s proprietary insulation technology, featuring suspended layers of ultra-thin, metallised film anchored within the pad's internal baffle structure, which reflects radiative body heat back toward the sleeper while blocking ground cold from seeping upward.
• Body-Mapped Contouring: Gently cradles your body toward the centre of the mat to ensure you stay comfortably aligned throughout the night.
• High-Performance 6.2 R-Value: Built with dual layers of reflective film insulation to deliver reliable four-season thermal protection on cold, frozen ground.
• Vortex Pump Sack: Included, for rapid, effortless inflation without introducing interior moisture from condensation.
• Micro-Adjustable Laylow Valve: Low-profile zero-profile valve provides effortless air release and micro-adjustable firmness control while lying down.
• Lightweight and Compact Build: Highly packable design tailored for minimal trail weight during extended backpacking journeys.
• Versatile Rectangular Shape: Standard footprint dimensions provide complete body coverage while fitting seamlessly into tent spaces.
