Men's Project One Ultra Compression Shorts | 15-20 mmHg Graduated Compression

Built breathable. Built to last. Built for Hyrox.

Overview

The SA1NT P1 Ultra Compression Shorts introduce 360° stretch waist pockets placed around the entire waistband. Carry gels, supplements and a phone without bounce. Breathable, moisture-wicking, water-resistant fabric is engineered for long-distance and obstacle racing where you need real on-body storage and graduated compression that doesn't compromise.

Will these overheat in summer or during a Hyrox?

No. The P1 Ultra uses a lightweight, water-resistant circular-knit fabric engineered for sweat, rain and splash. Moisture moves away, the fabric stays light and dries fast. Graduated compression supports circulation without trapping heat, so they perform across multi-hour Hyrox heats, ultras and Spartan races.

Key Features

• 360° waist pockets: stretch storage placed around the entire waistband for gels, supplements, keys and a phone
• Breathable, water-resistant, quick-drying fabric: stays lightweight even when soaked with sweat, rain or splash
• Graduated compression: medical-grade pressure profile supports muscle stability, reduces oscillation, accelerates recovery
• Muscle Mapping+ silicon print: targeted silicon detail on the inside of the thighs supports the quadriceps under load
• High-performance circular knit: strong, lightweight, engineered for shape retention through repeated use
• Flatlock seam construction: ergonomically patterned to reduce chafing over ultra distances
• 9-inch (23cm) inseam: longer cut to support a broader range of leg muscle

Built to Last

Engineered to outlast cheap compression. 3-needle flatlock seams resist the abrasion that creates holes in running tights. Dope-dyed yarns lock colour into the fibre core so it won't fade or bleed through repeated washing. The circular-knit fabric holds its graduated compression profile wash after wash. We build for years of use, not a season.

Why It's Worth It

At £99, the SA1NT P1 range sits at a premium price for a reason. 15-20 mmHg medical-grade graduated compression is rare at this point: many cheaper "compression" garments only apply uniform pressure that doesn't help circulation. Combined with dope-dyed durability and Australian engineering, this is built to last years rather than fail in a season. Cost-per-wear, it competes hard with anything in the 2XU, Skins or CEP price bracket.
