What if there was a sleeping bag that offered warmth in extreme climate teamed up with features that made it comfortable on a family camping holiday? Well look no further, the Sea To Summit Latitude LtII 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 provide an amazing balance of warmth and comfort, all at just over 1kg. 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 a miniscule 7.5L of volume in your pack and comes with a laundry bag/storage cell for when your adventure is over. So you don’t need a bag for each season, with the Sea To Summit Latitude LtII you have a sleeping bag for every season.
This is a prelim rating. Not used in anger yet (bad conditions). But the size, weight and features of this bag are very good. Great size and weight for larger person to still be comfortable. Packs into extremely small bag for its size. Weight is very good for bag size. Hard to pack really, but it does. The outer material is quite tough, and no doubt water resistant. The loft in the bag is great, thats where it really impresses. Loft means warmth, and this defies gravity. Great make and design with zips/ size etc. Will review again after angry cold trip away. Great product though. Recommend.
My son is going to Nepal to Anapurna base camp and needs a minus 10 bag. What is the difference between the Latitude II (minus 9) and the Trek III (minus 11)? Would either be equally suitable? Thanks
The Latitude II Has a higher volume of down at 750 compared to 650 for the Trek, and is slightly also lighter, with a smaller packed size compared to the Trek III.
We would actually recommend going for a Latitude LtIII which has a comfort temperature limit of -10 and lower temperature limit of -17.
This is because you want to make sure the lower minimum temperature rating is comfortably lower than the lowest temperature you will potentially experience. It’s better to be cautious when it comes to temperature ratings in very cold conditions, as you can always unzip if you are too warm, but if you're too cold there's not much you can do.
Also, with any down bag we would recommend adding a liner as well, as it’ll extend the life of the bag and also add to warmth and overall comfort. If you have any further questions, please don’t hesitate to give us a call.
Hello, can you please tell me if the Latitude sleeping bag opens out so it can be used as a doona?
The Latitude has a full length zip that meets a foot zip so when you undo both of them you can use it like a doona yes.
The differences between the Latitude and Talus range indeed what you've mentioned, as well as the different comfort temperature rating and lower temperature rating.
The Latitude is designed to be a little more versatile, whereas the Talus is more of a traditional mummy style bag - so if you prefer more room to move around, the Latitude would be your best bet.
I am 184cm and the Regular length is shown as suitable for sleepers up to 183cm. Will that extra 1cm really mean I need the Long (which weighs an extra 110g)?
The Latitude has a tapered foot box, so I think a centimetre won’t matter too much as there is a bit of space to move but it really depends on what you’re going to be comfortable with. If you like a bit more room then maybe size up, but if you prefer a snug bag then the regular might be the better option.
I am a cold sleeper normally, but don't have too much experience with sleeping bag temperature ratings. Any suggestions?
Hi Jason, sleeping bag ratings are more of a guide than a firm rule, it very much depends on the individual. You may find the Lt3 bag too hot on most nights, so I'd recommend the Lt2 for spring and autumn conditions in Victoria. This should see the average person sleeping comfortably down to about -3 °C. You can then scale the comfort of this bag with the addition of sleep liners, thermal clothing and if it's really cold, a hot chocolate before you climb into bed, this will get your metabolism going and generate more heat inside the bag. It's also important to note that you should use an insulated sleeping mat, even the warmest bag will not insulate well if the user is sleeping on a mat that does not insulate against the cold ground. It's not an easy decision, give us a call on 1300 914 007 if you would like to talk to one of our team about this in more detail.
