Should a Base Layer Be Tight?
Your base layer should ideally fit snug but not tight. Here's a breakdown of the ideal fit:
- The base layer should skim your curves comfortably without sagging or bagging. This close fit lets the material wick sweat away from your skin effectively.
- Your base layer should allow you to move freely and comfortably. Avoid anything that digs in or feels restrictive.
- Think of your base layer as a second skin, not a compression suit.
- If you're between sizes or prefer a looser fit, consider sizing up in your base layer.
- Different materials may hug your body differently. For example, merino wool naturally has a more forgiving drape than synthetic materials.
By finding the right balance between snug and loose, you'll get the most out of your base layer in comfort and performance.
