Ultra-Lightweight Down Performance From Sea to Summit — Brand New, Brand Sample

This Sea to Summit Spark Pro Down 30 Degree Sleeping Bag sits at the top of Sea to Summit's ultralight sleeping bag lineup. The Spark Pro is engineered for backpackers and alpinists who refuse to compromise on warmth-to-weight ratio — delivering genuine 30°F comfort in a package that packs down impressively small and weighs next to nothing. 

Size: Regular
Color: Grey
Condition: Sample - New with Original Tags, Brand Sample
Original Retail: $549

Key Features:

  • Premium Down Fill: High-loft down insulation engineered for maximum warmth-to-weight efficiency in a compact, compressible package
  • 30°F Comfort Rating: Designed for three-season backpacking and shoulder-season alpine use where weight and packability are critical
  • Ultralight Construction: Sea to Summit's Spark Pro series is built for gram-counters who want serious performance without the weight penalty
  • Nano-Dry Down Treatment: Hydrophobic down treatment that maintains loft and warmth even in damp conditions
  • Compression Stuff Sack Included: Packs down to an impressively small volume for its warmth rating, ideal for technical packs with limited space

Ideal For: This is the bag for serious backpackers, fastpackers, and alpine climbers who need a legitimate three-season bag that won't weigh them down. As a brand sample in new condition with original tags, it's never been slept in — you're getting a $549 ultralight sleeping bag at a significant discount. If weight and packability are priorities in your kit, the Sea to Summit Spark Pro is one of the best options on the market, and this is a rare chance to get one at a pre-owned price without any of the wear.
