The RAB Outpost 300 is a two-season, blanket-style sleeping bag designed for camping nights that stay cool but not harsh. Its roomy 220 × 160 cm dimensions make it easy to share or spread out in, and it’s rated for comfort down to +10 °C for women and +5 °C for men.
Inside you’ll find 650 fill power European duck down, which offers a high warmth-to-weight ratio and compresses neatly for packing. Both the shell and lining are made from recycled 30D polyamide, giving you a lightweight yet tough exterior that resists wear and a soft interior that feels good against the skin.
The 650 fill power rating refers to the volume that one ounce of down occupies when fully lofted—higher numbers mean better insulating efficiency. Meanwhile, 30D (denier) polyamide indicates a fine, low-bulk yarn that balances durability with packability, so the bag remains both resilient and easy to stow.
