Gloves or Mittens? All things being equal (fabrics, thickness, and insulation), mittens are warmer than gloves. Mitts trap body heat by keeping your fingers together and reducing evaporative heat loss. In frigid temperatures, a layered mitt system is the best choice for warmth. Layers dry faster than one heavily insulated piece, and let you swap out wet ...

This is simply a question of the increased surface area of gloves which will therefore increase temperature (heat flux) exchange. Similar reason why foxes have bigger ears as closer they are located to the equator, to increase heat flux and in this case lower the body temperature of the fox. In case of your gloves this isn't beneficial for you in case of ...

As other people have mentioned mittens are warmer in almost all circumstances, a large part of this is that your entire hand is keeping the inside warm rather than each finger trying to warm itself individually. Where they fall down is when you need to take your hand out of the mitts, everything from taking photos to having something to eat becomes a chore ...

35° is 35°, whether in your car, in your pack, or in your refrigerator back home. However, handling raw meat otherwise is very different outdoors than at home. Personally, I think bringing raw meat into the wilderness is a bad idea. There are plenty of other foods that give you the same or better nutrition, don't require as careful handling, weigh ...

As with clothes you were wearing while you climbed, the liner boots are damp - if not wet from the days activity. Energy is required to evaporate the moisture - this cools you down, including your feet. You get cold from it very easily. Also as most people will feel cold if they have cold feet, so you will feel cold even if you are actually warm enough. In ...

So at 5C, with 60Kmh winds, that gives you a feeling of about -2C See here. Not zero, If the air temperature gets to 0C then there's a potential for about -9C. You want to be aiming for a laying system so you can adjust your core temperature with movement, if you stop you'll want something to keep you warm. I'm not sure you have anything like that in that ...

How much water you need depends on how big you are, how fit you are, where you are and what you're doing. For example, on Mount Everest, the average person needs to drink 4-5L of water each day just so that their body can function properly. You lose water through your breath, perspiration, urine and bowel movements. If you're a big guy that's out of shape, ...

The standard expedition stove for extreme conditions would be an MSR XGK. You will likely want to bring a pair of them, along with a repair kit, on the assumption that due to the cold or poor quality fuel you'll break a pump or need to make other repairs. Now, you may be thinking "what are all those people doing with canister stoves on ...

This seems a bit low to me, but there are lots of other factors to consider. The main ones are temperature and exertion/walking speed. Different people also definitely need different amounts of water. One of my friends was nicknamed desert-man as he drank approximately 4x as much as everyone else. If you are in the UK or a similarly cool climate, then 100ml ...

The variety used by pipe fitters working the oil fields in the Great White North: You sound like you're working on the oil rigs, which explains why the pointer finger on your gloves keeps blowing out. Ski gloves and climbing gloves aren't going to take the abuse of turning pipe all day, what you need is a sturdy pair of leather gloves with a reinforced ...

Pneumonia is not what you have to be worried about in this situation. It is a serious pathologic condition of the lungs commonly (but not exclusively) cause by viral or bacterial infection. Unless you were previously infected it is not likely to catch anything away from civilization. There is a widespread notion of a relation between being cold and catching ...

Could the use of anti-perspirant give benefit in extreme cold climate where sweating can be a significant problem. TL;DR answer: Unlikely. The issue is the sheer amount of water your body will secrete during physical exercise. It would be impossible for anti persperant to prevent this amount of moisture. To clarify Anti-perspirants work by: ...

Mittens are normally warmer than gloves. On The most expeditions (high mountains or very cold temperature) the most people wear thick down/synthetic mittens, because they're warmer than gloves. The blood flow in one finger is not that much and so it helps if all fingers are on one big mitten. And it's also not possible and practical in use to produce very ...

I found this interesting article on the topic of cold weather and hydration. http://www.unh.edu/news/news_releases/2005/january/sk_050128cold.html In cold weather you lose significant moisture just by breathing the dry air. Even in 100% humidity ( very rare in winter) the cold air can suck moisture from your lungs since it warms up in the lungs and can ...

No, 100 ml per hour is way too little in many circumstances. That would mean only 1 l over a 10 hour hike. Anyone that's been on a 10 hour hike, even not in particularly hot or dry weather, can tell you that's not nearly enough. For hiking in hot desert conditions, 1 l per hour (10 times your suggestion) is more like it. I have done significant hiking in ...

This depends on the actual type of clothing and mostly on the wind speed. The wind evaporates moisture from the body. Since evaporation is a cooling process and absorbs latent heat away from the body, the person feels colder. Skin always has moisture on it. Just like a tree transpires, the human body is constantly having water evaporated from it. Wind ...

I would add that I did Jiri to EBC in Feb 1992 (the coldest time of year?) and found it to be cold (4 season sleeping bag) but manageable. I am just re-reading my diary from the time - and the noticeable thing is that the cold is mentioned quite a lot - but my 'whining about the cold' is ALWAYS related to wind. So make sure you have windproof gear handy to ...

There is a definite danger of hypothermia depending upon the "type" of tent you choose to use. Eskimos live in -70F environments from one day to the next, so it is doable certainly. Native Americans as cited above have tents to provide for living in environments that commonly get to -50F (by keeping a fire burning inside the tent). A TeePee isn't what I ...

I am presuming this is not a hypothetical survival situation and it can be planned for. I used to regularly walked in wet boots for days, often in near (although rarely below) 0 degree temperatures, although pass hopping we could spend most of a day above the snow line with wet boots. A typical week to 10 day trip where I live you will cross a river ...

I would add an extra insulation layer for the morning. A light down or synthetic jacket would help you warm up when you get out of bed. Don't wear cotton pants. Not only will they keep you cold if they get wet, they will never dry, and will be very uncomfortable. When it does not rain, you'd want your fleece to be wind-stopper, or have a windproof jacket ...

When I was in central Alaska, courtesy of Uncle Sam, we wore vapor barrier boots. They are great for extremely low temperatures, but of you are heavily exerting in milder weather* (down to -23C/-10F range), your socks would get downright soggy. Some soldiers did put anti-perspirant on their feet to help with cold and trench foot symptoms. If plastic ...

I just browsed the meta site, and am encouraged to add an answer. I agree with the above answers and comments, especially (1) don't wear cotton pants; (2) carry spare socks and mitts; (3) poly is lighter and warmer than wool when wet; (4) your clothing is on the light side; consider the additions suggested. I'd ADD: a neck gaiter. This is a fleece tube ...

When meteorologists tell you the temperature, likely they mean the temperature more than 1m off the ground in a shaded place (for example in a Stevenson screen). Anything sunlit is likely to be warmer. The ground is likely to be different (warmer or cooler depending what else is going on). You can't assume that just because the weather report for the region ...

Several people have already mentioned getting special gloves that have "flippable" finger tips, but no one has specifically mentioned sensory gloves which can be a little bit different than gloves that just flip their tips. In addition to flip-tips they also have a little hole that you can touch through, so you don't actually have to take your finger tip all ...

If you burry your bottle in snow it should be less likely to freeze. The snow is a great insulator and burying the bottle completely should keep the heat from escaping. Essentially you are making a quinsy for you bottle (but much less effort!).

Keep the bag Warm not your clothes! Both clothes and sleeping bags are insulators, the problem with wearing too many clothes in your sleeping bag is that you will actually insulate yourself independent of the bag, as a result, your bag won't get warm or it will take a long time to warm up. You will eventually have issues with moisture control, as your bag ...

48 hours is very definitively too long for your feet to be wet, even regardless of temperature. https://en.wikipedia.org/wiki/Immersion_foot_syndromes From the CDC article "Injury occurs because wet feet lose heat 25-times faster than dry feet. Therefore, to prevent heat loss, the body constricts blood vessels to shut down circulation in the feet. Skin ...

You're sleeping bag only works if you can get it warm. If you wear too many clothes in your sleeping bag, you're not going to fill the loft of your expensive down mummy with cozy warm body heat. This is what can happen if you're wearing your liners in bed, the bag around your feet doesn't warm up. I think whether or not you get cold toes depends a lot on ...

Most ski gloves will have a waterproof/breathable layer (Gore-Tex or something similar, they should be labelled to say what it is). In my experience new gloves also seem to have a water repellant on the fabric to help water drops fall off before they get to the Gore-Tex. This surface water repellant will wear away and could be refreshed with various spray-on ...

Piece of cake. I was working for St. John's Cathedral Boys' School in the late 70's. The school had a winter program that included week long dog sled expeditions. We had the odd case of frostbite, but nothing serious. On a bet, I slept under a tarp for a year. It wasn't a fancy setup. I started in the fall, and threw a tarp over a large willow bush, ...
