Imagine a sleeping bag that kept you warm in extreme climates but was designed with a balance of features that made it comfortable on a family camping getaway? Well look no further, the Sea To Summit Latitude LtIII is an amazingly warm bag with 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 provide an amazing balance of warmth and comfort. Nothing has been left out in the interest of saving weight, draft tube, neck baffle, three dimensional hood and draw-cords to keep the warmth in, the Latitude is a fully featured bag.

They’ve even included an internal zippered accessory pocket! Once compressed the Latitude takes up just 9.5L of volume in your pack and comes with a laundry bag/storage cell for when your adventure is over. If you’re looking to keep yourself warm on the summit of Kosciusko in the middle of winter, the Sea To Summit Latitude LtIII is the bag for you.

Great Value

I recently brought this sleeping bag and took on the Frenchman's Cap hike in Tasmania, it was absolutely fantastic, light, compact and extremely warm.
Great price and exceptional service from Snowy's.

Did the job well

I bought the Latitude III for my trip to Nepal trekking along the Everest Base Camp trail. I was extremely pleased with the bag, it was warm enough (although we only had temperatures around zero degrees) and roomy enough. Hood pulled around my head fine. Compressed well into its bag. It also comes with a storage bag too. When taken out of its compression bag it fluffs up well. It would have been nice to have a pocket inside as I slept with mobile and camera to try and maintain battery charge in the cold...but this is a minor criticism. Good price, good service from Snowys; no hesitation in recommending this bag.

have enquiries re the following bag Nothing is mentioned re the fabric down and water resistance qualities eg. other bags have a Pertex Endurance shell is brilliant in damp conditions, providing excellent breathability and water resistance at minimum weight. An inner of highly breathable, 15-denier Vapour Vent fabric saves

G'day Thomas, 

I've spoken to Sea to Summit, and they've given me the following information about your queries: 

The Latitude uses a micro-porous coating on a 20 denier nylon to create a waterproof/breathable shell fabric. The specs of the Latitude's fabric (water head and breathability) are very similar to the Pertex Endurance product, though it's marginally heavier to provide better durability. 

Those specs are not published by Sea to Summit as they are constantly working to improve them. Because they work directly with Fabric Mills (rather than just buy fabric in the marketplace) they can keep tinkering and changing the fabric to make it better.

The outer fabric also works extremely well in damp conditions, as well as offering excellent breathability to vent perspiration during use.

I hope this fully answers your question about the Latitude LtIII, let us know if you need any more information.

Latitude 3 or Talus 3?1 answers

Hi there, I have been looking at these 2 sleeping bags and the differences seem fairly minor. Talus compressed volume is 9.15L, Latitude is slightly bigger at 9.6L. Latitude has a bit more room at the hips and feet. Latitude has a foot opening, Talus doesn't. Talus has 3D side walls, Latitude doesn't. Talus weighs 1225g, Latitude weighs 1290g. So my questions: Are there any pros or cons to either bag I am missing? Are 3D side walls much of an advantage? I don't really get what this is. I am 160cm and 63kg female, would you suggest a short sleeping bag? For 2 sleeping bags to be zipped together I assume they would need to be the same size, is this the case, or can short and regular awkwardly zip together somehow? I am a very cold sleeper and intend to use the bag for 3 season hiking and camping so warmth, compressed size, and weight are all important. Thanks!

G'day Jo,

There are some minor differences between the Talus and the Latitude. The Talus has a slightly narrower foot end, at 107cm compared to a little more generous Latitude 118cm, and the Latitude offers a double zipper instead of the single in the Talus.

The rest of the features of the two Sleeping Bags are very comparible.
