In the world of snow fun, there are sleds, there are tea-trays and there are even plastic bin bags (if you are a suicidal sledger, as I was in my teenage years). And then there is this, the Alu sled. Built from aluminum, the shock-absorbent silver slider has plastic runners, a handbrake, and packs up into a sexy little carry case when you're done tobogganing (see below).
The lightweight Alu will carry up to 220 pounds, but will really lighten your wallet, as it will set you back a steep $636. [Sci-Fi Tech]
