I agree with dvalliere, you will have to spend some money, you don't have to do it all at once though. That's what off seasons are for... Tight is bad, cotton is bad, wet is bad.. You need moisture wicking clothes and make sure you layer it well. When I was young my dad used to bundle me up with every piece of clothing he could find to "keep me warm" and it never worked. I don't wear very much clothing even hunting on below zero days during late season but the clothes I wear are high quality.. Outer garments such as wool and Berber are Great clothes on the dry days but don't do a ton of good when they get wet.. Invest in less clothes but high quality and you will see a HUGE difference in your comfort level. Also, don't wear all the stuff into your tree, get a cheap backpack or mountain pack and dress light walking into your stand, give yourself plenty of time to get there and get changed into your warm gear once you get to the stand, if you get sweated up going in, it's almost impossible to get warm again once you cool off. Moisture wicking bottom couple layers are VERY important. Also, if your comfortable in your stand, you will be able to sit longer and be more still and it will up your odds on harvesting a animal. The more time your in your tree and doing things right the more success you will have... The scent killer/blocker clothing and clothes wash, dryer sheets, hair wash, under arm deoderant, body and hair lotion all work well and are a huge advantage we have to staying "scent free" use it all, its a system that works well... good luck to you. Remember you don't have to buy it all at once but you will get what you pay for... Shoot straight and good luck
