A hiking shirt should feel comfortable under your pack and suit the exposure. Fabric marketing matters less than how the actual garment performs for you.
Check fit and friction
Try the shirt with shoulder straps and a loaded pack. Notice seams at shoulders and underarms. Choose movement and coverage you can sustain for a long walk, not only a style that feels good standing still.
Compare care and drying
Read fabric and washing instructions. Test it during a local walk before the holiday. If sun protection is a priority, check the product's stated protection rather than assuming every thin shirt provides the same coverage.
Keep a complete clothing plan
Warm weather does not eliminate the need for suitable spare layers on higher routes. Read the summer clothing guide. Ask Atlas Hikes about the actual terrain and exposure before buying several copies of one supposedly perfect trekking T-shirt.
