Nalgene 32oz Insulated Bottle Sleeve — Survives Sub-Zero, Zip Seal + Carry Loop! $31.17 CAD (42% Off)

Amazon.ca has the Nalgene 32oz insulated bottle sleeve in Teal for CA$31.17 (list CA$53.92, 42% off). Free shipping for Prime members; otherwise free on orders over CA$35.

This isn't the plain neoprene sleeve — it's the insulated version. The zip closure wraps the whole bottle, there's a carry loop, and it fits both wide-mouth and narrow-mouth Nalgenes. Two problems it solves: water turning to slush on a winter hike, and water going warm in a hot car.

4.4 stars over 89 reviews, and the use cases people describe are fairly hardcore: one owner ran it on 10-12 hour hikes at minus 10°F and the water never froze; another left a bottle in a hot parking-lot car and it was still cold hours later.

Being honest, thirty-odd dollars for a sleeve is not cheap — more than the bottle itself. But if your pattern is winter day trips or full days outdoors, it beats buying a second insulated bottle: a 32oz vacuum bottle doesn't exist in this form factor and isn't as easy to drink from.
