The hiking weather was perfect, but temps in the mountains plummet at night, so make sure you're prepared with the Haglofs Lupus 8C Synthetic Sleeping Bag. This affordable trekking mummy bag features Tri Fusion insulation for lightweight warmth and plenty of technical features to help you on your adventure. The mummy shape reduces bulk when packed and increases thermal efficiency by hugging your body. Anti snag tape ensures the zipper opens and closes smoothly, and elastic adjustment at the collar lets you get the fit just right. An internal mesh pocket stores items you want to keep warm, such as batteries or fuel canisters, and the pillow pocket keeps your head cushion from shifting around at night.
