Better than Basic Sleeping Mat - Deluxe STS Self Inflating
Discover a new standard of trail comfort with GPWC/AO’s Deluxe STS Self Inflating Sleeping Mat. Lightweight, insulated, and designed for warmth and support—your best night's sleep on the trail is within reach.
In the heart of Victoria’s rugged Grampians region, where sandstone cliffs rise sharply against a vast sky and native eucalyptus forests hum with life, GPWC/AO delivers a vital piece of gear designed to transform overnight wilderness stays: the Deluxe STS Self Inflating Sleeping Mat. Based out of Halls Gap, the gateway town to this famously raw landscape, GPWC/AO understands the demands of backcountry adventurers who need reliable rest amid the wild. The Grampians National Park offers a playground of rocky pinnacles, cascading waterfalls, and rich Aboriginal cultural heritage dating back thousands of years—grueling terrain by day and tranquil starlit campsites by night.
Here, comfort and warmth on the ground are more than luxuries; they’re essentials for recovery after long treks or climbing pursuits. Weighing in at just 780 grams and measuring 3.8cm thick, this lightweight, insulated self-inflating mat from Sea to Summit balances portability with performance. Its R-value of 4.2 means it shields you effectively from the notoriously chilly ground, keeping the cold at bay so sleep isn’t compromised by damp earth or lingering evening chills.
Its compact size packs easily, letting hikers ditch bulky gear in favor of nimble travel. GPWC/AO’s rental option also provides a gateway for curious campers to test the mat’s comfort first-hand—rental fees even apply toward purchase if you fall for it. This try-before-you-buy model aligns perfectly with the practical needs of those who know a good night’s rest can define the quality of a trip.
Serving as both outfitter and gear innovator in Halls Gap, GPWC/AO ties the comfort and convenience of modern equipment directly to the raw, elemental experience of the Grampians. When every ounce matters and every hour of sleep counts, this deluxe mat is a small upgrade with a big impact on your outdoor adventure experience.
