OMG, STOP! Do NOT Buy- Soooo MISLEADING !- Rynoskin advertises these 'socks' along with all their other clothing products that mosquitos do not bite thru… So, I thought they were made from the same mosquito repellant fabric as all their other clothing items for sale- BUT ‘NOT’… In the Q&A it even says that (which I missed): “They are basically like pantyhose.” Do NOT Waste your money- You can buy some stocking socks panty hose for MUCH CHEAPER… In the Q&A also says: “These socks are chemical free and are only just used as a 'base layer' to protect against bites”… which just means- the more layers of thickness clothing you wear- the harder it is for mosquito stingers to go through yet another layer of clothing- but this is like the thinnest material ever made- so, like it’s not much of a layer at all- Very LITTLE Protection (like NONE) is what I’m saying here- like panty hose... I can't beleive they even say in Q&A that such a thin layer helps prevent bites... Q&A says: “The fabric is made from Nylon and Lycra”. I wish I had known! Now beyond return period before I tried them out- So very sad you must 'read through all the Q&A' jsut to make sure you are buying something you think is within same line/type as all other Rynoskin products... But, the SNUCK this one in- and I got stiffed with the cost of bying some panty hose and 3 mosquito bites on my foot and ankles... before I even realized this does NOTHING to stop mosquito bites !!!Quality is great but the socks fit too tight, I'm a 12 shoe size. They should make a XL size.Excellent sock replacement to keep mosquitoes off your feet. Breathable, doesn't get hot and material can be overlapped with bottoms on.I wore them and did not get bit on the ankles and feet while working in my garden. However, these things are made for 12 yr olds with super skinny calves. They did fit my feet but when I tried to pull them up my leg, I couldn't get them to fit. I had to fold them over which led to bits on my legs although I was wearing joggers. They are one size but don't have any stretch in them to make them work on your calves.Great for people who are highly sensitive to stinging/biting insects. I literally watched mosquitoes crawling along the fabric trying to find an entry point, but couldn't. However, the fabric is incredible breathable and lightweight.I work in a forest. Socks are comfortable and give me a piece of mind. I wear these socks with my Rynoskin leggings/pants.They worked greatThey really work! I went camping and I was saved by these socks!!!!Went camping and was eaten alive from the knees down. Bought these socks and went again the next weekend. No new bites! Great Success!!!Very tight fit. Order next size upRynoskin did not protect against mosquitoes.peace of mind
