Compare Vapor Lite tees, singlets, and the fitted shimlet across 2025 and 2026 custom designs, with fit guidance for building a team running kit.
Quick answer
Choose a Vapor Lite tee for everyday training and a looser athletic cut, a Vapor Lite interval singlet for hot-weather speed work, and the fitted shimlet only if you want a tight, race-ready fit. The 2025 and 2026 labels mark design cycles, not fabric changes.
The 2025 vs 2026 difference is the design, not the fabric
Every item in this comparison is made from the same Vapor Lite fabric: ultra-lightweight perforated polyester with mechanical four-way stretch and moisture-wicking performance. The year in the product name refers to the custom design cycle, so your choice should come down to cut and fit, not the date.
That matters for custom running kit design because you can mix a 2025 tee with a 2026 singlet without worrying about mismatched fabric performance. Pick each piece by how you want it to fit.
Tee vs singlet vs shimlet: three different jobs
The men's short sleeve tee uses an athletic cut that fits true to size and works on the run, at a race, or around town. It is the most forgiving option for everyday training and mixed use.
The women's interval singlet is a sleeveless Vapor Lite top with full front and rear perforation, which suits hot sessions and hard intervals. The men's sleeveless fitted singlet is a wideback race-cut top with a compression fit; most members size up, so choose it only if you like fitted tops.
The women's fitted shimlet is the most aggressive cut here: compression-style, tight, slick, and supportive. Most women size up, and the catalog notes it is not for anyone who dislikes a painted-on race kit.
Where the trade-off shows up
Looser cuts buy comfort and versatility but give up some of the locked-in race feel. Compression cuts deliver that race-ready fit but leave less room for layering or casual wear, and sizing up is common.
If your team wants one consistent look, the tee and interval singlet pair easily. If you want a sharp race-day kit, the fitted singlet and shimlet deliver it, but confirm sizes with the size charts before ordering.
Trade-offs by piece
- Men's short sleeve tee: Athletic cut, true to size, and usable on the run, at a race, or around town. Trade-off: less race-specific than a compression singlet.
- Women's interval singlet: Sleeveless Vapor Lite with full front and rear perforation for breathability. Trade-off: a singlet cut offers less coverage than a tee. Use the women's top size chart before ordering.
- Fitted singlet and shimlet: Compression-style race cuts; most members and most women size up. Trade-off: a tight, painted-on feel that is not for everyone. If you dislike fitted tops, choose the tee or interval singlet instead.
