Questions and answers
- Which is better for hot weather and workouts?
- The Mack Weldon Airknitx. It is the lighter, more breathable pair with targeted cool zones and fast-drying synthetic fabric. The Saxx is cotton-based and warmer.
- Which is cheaper?
- Per pair, the Saxx. The 3-pack is $34.87 at eBay as of November 3, 2026, about $11.62 a pair. The Airknitx is $21.99 for one pair as of November 1, 2026.
- Does the Mack Weldon have a fly?
- No. It uses a supportive flyless pouch. The Saxx Non-Stop Stretch has a fly opening.
- Which holds its shape longer?
- Both are built to resist bagging. Saxx uses a 9-panel Three-D Fit with flat seams; Mack Weldon uses four-way stretch with a no-roll waistband and stay-put legs. Cotton-blend Saxx may soften faster with heavy washing.
- Is the Saxx worth the extra over the Mack Weldon?
- Only if you want cotton, a fly and the pouch. Otherwise the Airknitx is cheaper per pair and cooler to wear.
- Which is better for hiking and travel?
- The Airknitx dries faster and packs lighter, which suits travel and sweaty days. The Saxx is fine for everyday wear and cooler climates.
