Everybody needs underwear and we’ve worn the lot. Great base layer? Check. The perfect long underwear? You betcha. Or maybe, just the best travel underoos or sports bra? Yep, we’ve tested those too. While it may seem inconsequential, wearing the right base can be the difference between a great experience or a cold or chaffing nightmare. After months of living large in underclothes, our experts have the inside line on what works best for each adventure, without bias and without brand allegiance.
