Great looking shirts that breathe and move well. The neck opening is fine on me, but for people with larger necks it could be 'too tight'. The weave makes these shirts very comfortable to wear casually, and the material is great for workouts as well. Careful when picking out your color though, as there can be tremendous variations in price depending on which reseller the order originates from. The shirts generally start around $12 when sold by Amazon, and have seen up to $25 for shirts sold by outside retailers and fulfilled by Amazon.
