Sea To Summit Traverse TV3 Left Zip Regular - Green

Sea To Summit Traverse TV3 Left Zip Regular - Green: Expedition-Ready Three-Season Synthetic Sleeping Bag for Cold-Weather Backpacking

When the temperature drops and the conditions turn demanding, the Sea to Summit Traverse TV3 Left Zip Regular in Green delivers the thermal performance and versatile ventilation system to keep you comfortable across South Africa's most challenging three-season environments. Stepping up from the TV2 with a colder temperature rating and enhanced insulation volume, the TV3 retains the same Free-Flow triple-zip system — full-length left-side, half-length right-side, and independent footbox zip — while adding the warmth needed to handle the Drakensberg in autumn, the Cedarberg in winter, and alpine conditions where temperatures push well below zero overnight. For serious backpackers, mountaineers, and year-round campers who need a dependable synthetic bag with genuine cold-weather credentials, the Traverse TV3 is the step-up performer in the Traverse lineup.

Key Benefits:

* Free-Flow Triple-Zip System: Full-length YKK #5 left-side zipper, half-length right-side zipper, and an independent footbox zipper provide unmatched ventilation control across a wide temperature range — from sealed expedition warmth in sub-zero conditions through to fully flat comforter configuration on mild nights, with every intermediate ventilation setting accessible on demand
* Higher-Volume WaveLoft THERMOLITE Insulation: Increased insulation fill over the TV2 in Sea to Summit's proprietary WaveLoft construction loops thick THERMOLITE hollow-core fibres together to create extra loft and trap larger air pockets — delivering the colder -9°C Lower Limit rating required for high-altitude and cold-season South African camping conditions
* Roomy Tapered Rectangular Shape: Wider-than-mummy tapered rectangular cut provides freedom of movement for all sleeping positions without excess dead air space that would reduce thermal efficiency — comfortable enough for restless sleepers, thermally efficient enough for genuine cold-weather performance
* Anti-Tangle Baffle Construction: Lining fabrics are stitched directly to the shell throughout the bag, preventing lining shift and tangles during sleep and ensuring consistent insulation distribution across the full body from hood to footbox across every night of use
* Shaped Hood and Draft Collar: Technical shaped hood seals closely around the head to retain warmth at the most critical heat-loss point, with a separate draft collar at the shoulder zone blocking convective heat loss — a combination that makes a measurable temperature difference in genuine cold conditions
* Zip-Compatible Coupling System: The Traverse TV3 is designed to couple with compatible Sea to Summit sleeping bags via the zip coupling feature, creating a connected double bag system for couples or partners sharing a tent in cold conditions who want a warmer, combined sleep system

The Traverse TV3 Regular in Green is rated to -9°C Lower Limit with a comfort rating of -3°C, covering serious cold-weather camping across the full range of South African highland and mountain environments through three seasons. The 30D DWR nylon shell and 20D nylon lining keep the bag moisture-resistant and compressible into its included 70D nylon compression sack — essential for pack-in routes where overnight conditions can shift quickly from mild to cold. For South African adventurers pushing into the mountains year-round, the TV3 provides the warmth margin and ventilation flexibility to sleep well whatever the forecast.
