GSI Outdoors Microlite 1000 Twist Bottle



Microlite 1000 Twist Bottle

You might not believe the GSI Outdoors Microlite 1000 Twist Bottle is insulated because of how light and thin it was designed, but that doesn't mean it cannot keep your coffee toasty for half a day, or your frozen drinks cold for longer than a day. Although thinner, this bottle's vacuum insulation maintains heat/cold just like the rest of them, and its thinner design holds more liquid for more drinking.
  • Insulated bottle made thinner than most insulated bottles
  • Vacuum insulation maintains 16 hours of heat and 32 hours of cold
  • Stainless steel construction provides purity and durability
  • Screw top cap is easy to open even when everything is frozen
  • Item #GSI007C

Lightweight with some nice features

I've used it several times

This GSI bottle is a nice alternative to some of the better-known insulated steel bottle brands. -it's lighter-weight than hydro flask and yeti, yet it keeps stuff very cold (or hot) just as well. -same highly durable steel as other high quality insulated steel bottles. -bottom is silicone/plastic. anyone who has dropped and dented the bottom of a steel water bottle knows this is a plus. -it's meaningfully less expensive than the better known brands -the cap is attached, which you may like or dislike. I have lost a few caps in my day, so having it attached is helpful. -only downside for me is the mouth of the bottle. it's nice and wide (not as wide as a comparable yeti rambler, similar to hydro flask), but the steel feels narrower/less rounded when you drink out of it.
