These boxers are comfortable, very soft, without being wimpy, and keep your core warm. These are not slippery like many synthetic fabrics which is nice.Pros: Great design, Build quality, Performance

These boxers are true to size, but ride lower than I prefer. I like boxers that ride at the waist, same as my pants for padding and comfort. XL should fit a waist 35-40".Pros: Build quality, Ease of use, Cons: ride low

I can't speak about the durability because I just bought them. The wool is extremely soft and comfortable and keeps you dry. The fit is true. The waistband is comfortable and the length seems to be a bit more than other brands, which is good for me. I would highly recommend them.Pros: Great design, Build quality, Performance, Ease of use, Cons: Cost
Must Have Travel Wear

Super soft, super comfortable and naturally antibacterial. Could travel for a month with two pair and never have that travel funk. The quality is fantastic as with all I/O Bio Gear. You'll likely never wear cotton again.Pros: Build quality, Performance, comfort, Cons: Cost
