Be visible and comfortable. Great jammers especially at this price. The size guide is pretty accurate, the product quality is good. After several swims they have come up like new every time. A great product.

No need to be dull in the pool! Great length & don’t shift whilst swimming

These are fabulous. Good fit, the fabric is lighter as you'd expect in the pictures but opaque when wet.

Love the pattern of these. Always like the race kit. Great fitting shorts, much longer than my normal style swimmies. Feel nice on

Bought another pair as love my Ronny's so that's all the recommendation you need to purchase. But just in case you aren't sold already - being a 3XL means you either have pairs of swimmers that fit or look stylish but SG have nailed both with this range. Off to get a 3rd pair now ...

My second pair of SG jammers, after getting the Ronny pair. Quality material, brilliant fit, and what really does it for me is that the drawstring comes out of two holes rather than one, this means your knot doesn't disappear within the jammers when you try to take them off - so simple, so effective.

Fit well on the leg but do leave a bit of a gap for us builders when sat in the steam room or sauna meaning you have to position yourself carefully - think this could be solved with being able to pull the drawstring slightly tighter

Love them! Brilliant fit. Quality material. Also, very simple design feature: draw strings come out of two separate wholes, meaning it’s much easier to find and untie that knot when you want to take them off again.

Love these swim jammers, so comfy and a great fit. Excellent at my local pool or in my wetsuit at the lake.
