Guides pick the Z Lite SOL because it never fails. It can’t pop, doesn’t absorb water, and offers dependable insulation in any conditions. Lightweight and compact, it’s the perfect backup or supplement to an inflatable pad—and just as useful as a quick seat or emergency bivy mat. For guides, it’s a no-brainer piece of kit that earns its spot every time.

Ultralight Durability with Boosted Warmth

The Therm-a-Rest Z Lite SOL is the classic closed-cell foam pad with a performance upgrade: a reflective ThermaCapture™ surface that boosts warmth by 15%. At just 10–14 oz, it’s the lightest and most compact closed-cell pad available, folding accordion-style for fast setup and easy packing. Bombproof, versatile, and endlessly useful, it’s the pad guides count on season after season.

Our Take

The Z Lite SOL is one of the most versatile pieces of gear in our guides’ kits. It’s indestructible, ultralight, and endlessly useful—whether as a primary pad for fast-and-light trips, a backup under an inflatable, or just a trail seat. It’s the definition of simple, reliable performance.

Guide Tip: Layer the Z Lite SOL under an inflatable pad like the NeoAir XLite NXT to boost warmth and protect against punctures. On glacier climbs, guides also use it as a quick belay seat or to insulate gear from snow.

Guides pick the Z Lite SOL because it never fails. It can’t pop, doesn’t absorb water, and offers dependable insulation in any conditions.

For guides, it’s a no-brainer piece of kit that earns its spot every time.

“When the temperature drops and you need that extra layer of insulation, there's nothing better than a closed-cell foam pad to layer with your inflatable sleeping pad. And when it comes to foam pads, the Z-Lite has been my go-to for years. ”

Our Philosophy

We Simplify Outfitting

Whittaker Mountaineering was born out of the need for RMI to make sure their clients had the appropriate gear to get to the top of Mt. Rainier safely. After decades of trying, reviewing, arguing-over, and recommending gear, we can’t help but know what we’re doing by this point. We know what works, we know what doesn’t, and we use that expertise to stock our store. 

Who are these guys?

Therm-a-Rest

Therm-a-Rest pioneered lightweight camping comfort with the first self-inflating pad and continues to lead with innovative, durable sleep systems. We carry them because their commitment to comfort, repairability, and long-term reliability makes them a trusted standard for mountaineers and backpackers alike.
