Mens Swim Jammers Blaze and Obsidian | Geometric Print

Mens Swim Jammers Blaze and Obsidian

Mens Swim Jammers Blaze and Obsidian, two Swimcore geometric prints in adult men's sizing from XS to 5XL. Blaze is bright yellow with red triangles, Obsidian is black with grey-green and white shards, and both carry the Swimcore logo on the front.

Blaze

Blaze is the one to be seen in: a yellow base covered in red triangles, each filled with fine lines, so it stays bright from the poolside. Our supplier describes the fabric as quick-drying and breathable, resistant to chlorine and UV, and finished with flatlock stitching for comfort.

Obsidian

Obsidian is the darker choice, with angular grey-green and white shards and a dotted texture over a black base. Our supplier describes it as chlorine resistant and fade resistant, with an elastic waistband for a secure hold.

Specification

• Designs: Blaze (yellow and red) and Obsidian (black, grey-green and white)
• Sizes: XS, S, M, L, XL, XXL, 3XL, 4XL and 5XL (adult men's sizing)
• Fit: a snug jammer cut from waist to just above the knee
• Branding: Swimcore logo on the front

The supplier describes the fit as offering compression and flexibility, and the jammer cut leaves your hips and knees a full range of motion for kicking. We do not claim extraordinary elasticity or core stability benefits, as neither has been measured.

Are these sized for adults or juniors?

Adults. Every size from XS to 5XL follows the adult men's measurements, so a slim teenager may fit an XS, but the range is not cut for children.

How do Blaze and Obsidian differ?

Only in the print. Blaze is the bright yellow and red design and Obsidian is the dark black and green one; each pair is a single design. For other printed styles, see our Voltweb and Shatterstrike, and our Hydrostrike and Emberlash.

What size should I order?

Measure your waist and hips and check them against the size chart below. The size we list as XXL is the 2XL row, and the supplier notes a 2 to 3 cm tolerance on its measurements, so if you are between sizes the larger one will be more comfortable.

Are they World Aquatics approved for racing?

No approval is documented, so we cannot say they are World Aquatics approved. They suit training and club swimming; if you want to race in them, check your meet's rules first.

Do you deliver across the UK?

Yes, we deliver across the UK. If an order is delayed, it is because that size has sold out and is being replenished, and that will take no longer than 10 working days.
