What if there was a sleeping bag that offered roomy reliable warmth in a small package that was just as functional on a summer holiday? Well look no further, the Sea To Summit Latitude LtI is a tapered and efficient bag that offers extra room around the chest and feet, and a full length zip so you can open it right out in mild conditions.

A differential cut construction combined with offset baffles and a tapered roomy foot section all at a sub 1kg weight. No warmth trapping features have been left out, draft tube, neck baffle, three dimensional hood and draw-cords complete the Latitude as a fully featured bag.

They’ve even included an internal zippered accessory pocket! Once compressed the Latitude takes up a miniscule 5.5L of volume in your pack and comes with a laundry bag/storage cell for when your adventure is over. So you don’t need multiple bags, the Sea To Summit Latitude LtI is a lightweight bag for all year use.

  • Tapered rectangular shape
  • 60 top / 40 bottom down distribution
  • Roomy chest and foot sections
  • Full length side and foot zip
  • Can be opened to full duvet

Sleeping bag

Found Sea to Summit items on display in an Alaskan shop window (in Seward). That says a lot!
Slept naked in this bag with with the foot box unzipped while ice layed outside the tent at the Igloo Campground in the Denali National Park - Alaska during a cold, wet night on 1st June 2016. Was warm enough!
Due to the thinness of the bag under one`s pressure points however, it is vitally important that a good insulating groundmat be used, or underneath will be by far the coldest part.

Wow! All the way up there in Alaska! Thanks for leaving your review Vaughan, great to hear how S2S Latitude LtI performs in the coldest of conditions.

Bag ratings = Confused!1 answer

LoL! Ready to spend the cash but really not sure which one to go forLt1 or 2 Mainly camping 3 hours or so from Brisbane, mid winter at Girraween or Sundown can mean -5°c. So cold in any ones rating! So, a thinner bag and a good liner for winter or What? Saves on weight for Spring and Autumn Thanks for the advice.

G'day Paul,

I think your spot on with the idea of going for the lighter bag and adding a liner in when it's going to get cold, that's certainly what I'd do. Have a look at the range of Sea to Summit Reacor Liners here. I'd say the lightest option, the Sea to Summit Thermolite Reactor, would be fine to help push the Latitude I down to minus 5.

Comfort rating1 answer

You guys might want to rectify the comfort rating on these bags, for instance the ltI has a comfort rating of +2, the rating of -4 is the lower limit. Perhaps more detailed specs would help eleviate the issue.

Correct you are Ben, thanks for bringing this to our attention. STS highlight the lower limit in their ratings whereas the Comfort Rating is a more realistic figure for most users. We have some old system here at the moment but in the process of updating things which will enable us to display more information on our product page. Thanks for highlighting this, I'll fix up our temperature ratings right away.
