Three steps to cool.
Freeze the pack
Pop the slim gel pack in the freezer for a couple of hours. Two come in the box.
Slot it in
Slide it into the discreet front pocket. It sits flat and stays put — no bulk, no fuss.
Keep it cool
Go about your day. When it warms through, swap in the second pack — or wear them like any other boxer.

Questions, answered.
Does it actually keep you cool?
Yes — a frozen gel pack sits in the discreet front pocket and cools exactly where you feel the heat. Leave it out and it's simply a very good organic-cotton boxer.
How long does the cooling last?
Roughly 30–60 minutes of noticeable cool per pack, depending on the day. Two packs come in the box, so you can swap in a fresh one.
Is the pack comfortable to wear?
It's slim, flexible and sits flat against the front pocket — no bulk. Most people forget it's there.
How do I wash them?
Remove the gel pack, then machine wash cold on a gentle cycle and hang to dry. Flatlock seams and reinforced points are built for it.
How does sizing run?
True to size in M, L and XL — see the size guide on the product page. Between sizes? Size down for a snug fit.
Shipping & returns?
Free UK shipping, sent plastic-free. Unworn items can be returned within 30 days — for hygiene reasons, the gel packs can't be returned.
