Our verdict
The MIER SprintDry 2-in-1 shorts pack a lot into a $33 pair: a quick-dry outer short, a compression liner with 11% spandex and a built-in phone pocket, plus a hidden pocket for keys and cards. With 10 colors and sizes from XS to 3XL, it is easy to see why they top MIER's best-seller list. If you prefer an airy, unlined short, look at the PaceLite Linerless instead.

Overview
The MIER Men's SprintDry™ 2-in-1 Running Shorts 5" sit at the top of MIER's best-seller list, and the reason is easy to see on paper: for $32.99, you get a quick-dry outer short plus a compression liner with a built-in phone pocket, in 10 colors and sizes up to 3XL.
This review is based on MIER's official product information as of October 2026. Fit and comfort are personal, so we focus on the features, materials, sizing and value, and explain who these shorts suit best.
Design and features
Two shorts in one
A 2-in-1 short combines a loose outer short with a fitted inner compression liner. MIER says the liner is designed to support the thigh muscles, and many runners choose lined shorts to reduce inner-thigh chafing, while the outer short gives you coverage and a regular look for the gym or street.
Pockets for everything
Storage is where these shorts stand out:
- Phone pocket in the liner: your phone sits in the liner against your thigh instead of in a loose outer pocket.
- Two slant side pockets on the outer short.
- A small hidden pocket inside the right side pocket for keys, cash or cards.
The one thing missing is a zippered pocket on the outer short. If you want zips, see the PaceLite Linerless 5".
Fabric and fit
The outer short uses MIER's SprintDry™ quick-dry, moisture-wicking fabric. The liner is a 4-way stretch fabric with 11% spandex, with mesh air vents throughout for breathability. An elastic waistband with an internal drawstring lets you fine-tune the fit, and a side-split hem adds freedom of movement. MIER also lists the fabric as water-resistant with a color fastness rating of 4, and the shorts are machine washable.
A nice style detail: the top of the waistband matches the liner color, giving each colorway a two-tone look.
Sizing and colors
The shorts come in XS to 3XL and 10 color combinations. Use MIER's size chart on the product page. Since compression liners are designed to fit snugly, check the waist and thigh measurements carefully if you are between sizes.
Price and value
At $32.99, the SprintDry 2-in-1 is affordable for a short with this feature set: a compression liner, phone storage and quick-dry fabric. Add MIER's free shipping over $60 (two pairs qualify) and free 30-day returns, and the value is hard to argue with.
Who should buy them?
A great fit if you:
- Run with your phone and hate armbands or bouncing pockets.
- Get chafing with regular shorts and want liner support.
- Want one short for running, the gym and other sports.
Look elsewhere if you:
- Prefer an airy short without a liner. Try the PaceLite Linerless 5" with zip pockets.
- Want a shorter, racing-style cut. See the PaceLite Split 3" in our best MIER running shorts guide.
The bottom line
The MIER SprintDry 2-in-1 Running Shorts 5" deliver a genuinely useful combination of compression liner, phone pocket and quick-dry fabric for about $33. They are an easy recommendation for everyday runners and gym-goers, and free 30-day returns make it simple to check the fit. Read our full MIER brand review for more on shipping and returns.
