Tips for buying cold weather clothing
1. Look for military surplus that is actually NATO issued and not some knock-off. Surplus items sell at a discount which can save you a considerable amount of money.
2. If a zipper breaks, you're screwed in the field unless you have extra zippers on hand to stitch back in place. Buy extra zippers or the correct length now to replace any that are failing or did fail last season. Try to find buttons because usually they're easier to sew back on and seldom break outright. Check for missing buttons from last season, and consider sewing them with stronger thread and making them more secure.
3. Wear a cap. Most heat loss is through the head. Never go anywhere in your vehicle without a warm cap.
4. Consider buying a balaclava. It can be rolled up like a cap or cover the neck. Either way really helps you versus a standard cap. Try riding a bike in the winter without one. Bet you end up buying one. See: [link to upload.wikimedia.org
5. Buy gloves that are appropriate for the task. If you need to be dextrous then obviously you need a thinner pair. Buy some well insulated ones too. If you're out in lots of snow, then they should repel melting snow. If you're working in very wet snow, they make special rubberized ones for that purpose.
6. Consider buying ski pants if in the snow a lot, and having to kneel down. There's nothing worse than getting your pant wet and then icy and stiff. Every time I go skiing, I see a lot of people suffering from this.
7. Insulated coveralls are really great if you're working outside. It works on the layer concept. You can peal them off if you get too hot. That's important when going in and outside a lot and creating sweat. This prevents chills.
8. The same is true for insulated removable liners to jackets.
9. A thin polar fleece jacket is easy to put on, cheap, and sorta simple to remove. It's not ideal versus a jacket since it exposes flesh as you take it off sometimes. It's far less expensive than a good jacket or coat.
10. Thermal underwear of either silk or otherwise works remarkably well. Silk is a lot less heavier. Wool is better if there's any chance of getting wet. Mostly the latter is vital if working around frozen lakes and the ice breaks or the ice is thawing and you are doing river crossings.
11. Buy a pair of insulated full length boots with good treads. Ankle support is vital for long distances. Obviously if your region has snow then shorter boots are ridiculous. Sometimes people double their socks because their boots are not insulated. This can cause a lot of rubbing on long treks and is not recommended.
12. If buying camouflaged gear, then pick the appropriate pattern based upon the season. Wearing jungle camo in the dead of winter makes you stick out like a sore thumb. Wearing bright colors when crossing through deciduous and evergreen forest in Winter makes you stick out like a sore thumb too.
Most people don't buy the right kind of foul weather gear for Winter use. The reason is they're not used to actually being in it, much less working in it. Imagine being out in it a lot especially if ill prepared for a SHTF scenario.
Every read about Valley Forge during the Revolutionary War in the USA? You don't want to be like those poor miserable soldiers too.
