Pure Silk Interlock Thermal Long Johns (SIMJ)


Select a Colour

Special offer! Buy any two Silk Interlock from SIMC and SIMJ for only £132. Save £8.00! Your choice of style, size and colour. Discount will be calculated at checkout.

Super soft pure silk interlock makes these long johns special, a little extra silk weight to protect against the elements. With soft elasticated waistband and soft ribbing to the ankles and a fly front. The silk interlock seems to be made of two layers so it’s sometimes called a double knit fabric. Slightly thicker than our regular pure silk jersey, we think you will love this luxe baselayer.

Worn here with our crew neck vest code SIMV.
